The Best Shopify Apps to Increase Sales, Organised by Job (2026)

The Best Shopify Apps to Increase Sales, Organised by Job (2026)

Search for the best Shopify apps to increase sales and every list hands you the same thing: twenty apps ranked one to twenty, and app number one is usually sold by the company that wrote the list. The ranking tells you which vendor wrote the post, not which app will move your numbers.

That is backwards, because these apps do not compete. An email tool, an upsell widget and a reviews app are not rivals you choose between. They do different jobs, and a store that needs one usually needs three, just not always the three the list is pushing. I run a market research company, so I look at this from the demand side rather than the app-store side, and the honest version of this guide names the job before it names a tool.

So here is every Shopify app worth installing to increase sales, sorted by the job you are hiring it to do, with real 2026 pricing and the trade-off each one asks of you. Two kinds of app that show up on the classic lists earn no place here, and I will say why. And there is one lever no app can pull, which is where most of the wasted money goes, so I will come to that too.

Start here: what can an app actually do?

Before you install anything, get clear on how a Shopify app moves sales at all, because the honest answer rules out half the list straight away.

Your sales are roughly four things multiplied together: how many people arrive, how many of them buy, how much they spend when they do, and how often they come back. An app can touch three of those. It can lift the share of visitors who buy, raise the average order, and bring buyers back for another shop. What it cannot do is conjure traffic from nowhere, and it certainly cannot make someone want a product they do not want. Apps are multipliers. They act on demand that already exists. Point one at a page nobody was going to buy from and it multiplies zero.

That leaves five real jobs you can hire an app for:

The first is capture: turning the visitor who is not ready to buy today into an email or SMS subscriber you can reach tomorrow. Most of your traffic leaves without buying, and without a capture step you never hear from them again.

The second is conversion: giving the browser enough conviction to check out now, through reviews, trust signals and honest on-page nudges.

The third is average order value: getting the buyer who is already buying to add one more thing, through upsells, cross-sells and bundles.

The fourth is recovery: winning back the sale that got as far as the cart or the checkout and then stalled. This is the biggest single pool of nearly-money most stores have.

The fifth is retention: turning a one-time buyer into a repeat one with loyalty and referral mechanics, because the second sale to an existing customer is the cheapest sale you will ever make.

Name your weakest link before you shop. A store buried in traffic that will not convert has a different problem from one that converts well but never sees a second order. The apps below are grouped by those five jobs. Find your gap, then read only that section.

The best Shopify apps to increase sales, by job

If the job is capturing visitors who aren’t ready to buy

The maths here is stark. If your store converts at the ecommerce average, better than nine in ten visitors leave without buying. A capture tool is the difference between losing all of them and keeping a way to reach a slice of them later, which is why this is the first job most stores should fund.

Privy. The workhorse of list growth, and one of the most-reviewed capture apps on the store at a 4.5 rating. Privy runs email and SMS pop-ups, spin-to-win, exit-intent offers and abandoned-cart flows from one app, with templates that get a first pop-up live in an afternoon. Pricing starts at 12 US dollars a month and rises with your pageviews. Best for: stores that want capture and basic follow-up email in a single, cheap tool. Trade-off: it is a capable all-rounder rather than a best-in-class email platform, so a store serious about lifecycle marketing will outgrow the sending side and want Klaviyo or Omnisend alongside it.

Shopify Forms. Free, native, and the sensible default before you pay for anything. Shopify Forms builds email and lead-capture pop-ups and inline forms, hands the data straight to Shopify Email and your automations, and costs nothing. Best for: proving that capture is worth doing before you buy a specialist. Trade-off: it cannot place forms mid-page, has limited targeting and no spin-to-win gimmickry, so conversion on the pop-up itself tends to lag a tuned Privy or OptiMonk setup.

The honest move is to start on Shopify Forms, confirm the emails you collect actually turn into orders, and only then pay for a capture tool with sharper targeting.

If the job is turning browsers into buyers

Once someone is on the page, the question is whether they trust you enough to hand over a card. For a store nobody has heard of, that trust is mostly built by other customers, and the evidence for it is unusually strong. The Spiegel Research Center at Northwestern found that a product page showing five reviews converts, on average, 270% better than the same page with none, and that adding a verified-buyer badge lifts purchase likelihood by a further 15%. Reviews are not decoration. They are the single cheapest conversion lever most stores are leaving switched off.

Judge.me. The best value in reviews on Shopify, full stop. Judge.me holds a 5.0 rating across more than 31,000 reviews, is used by around 500,000 merchants, and its forever-free plan is genuinely useful rather than a trap: unlimited review requests, photo and video reviews, a storefront carousel and Google rich snippets, all at no cost. The paid Awesome plan is 15 US dollars a month for product grouping and more display control. Best for: almost everyone, and especially stores that want serious review functionality without a serious bill. Trade-off: the widgets look a touch more generic out of the box than the premium tools, so you will spend a little time on styling.

Loox. The visual-first pick, worth the premium if your product sells on how it looks. Loox rates 4.9 across nearly 8,000 reviews and specialises in photo and video reviews shown in polished galleries, with referral and upsell features layered on. A Beginner free plan launched in 2026 covers up to 100 review-request emails and 500 cumulative orders, then the Convert plan is 49.99 US dollars a month and Unlimited is 299.99. Best for: apparel, beauty, homeware and anything where a customer photo does the selling. Trade-off: materially more expensive than Judge.me for what is, for many stores, a similar job.

Hextom: Ultimate Sales Boost. The on-page conviction toolkit, at 4.8 across nearly 10,000 reviews. Hextom bundles more than thirty small nudges into one app: a free-shipping-progress bar, trust badges, stock counters, a get-it-by delivery timer and countdowns, placed across product, cart and checkout pages, and it has a free plan to start. Best for: adding honest urgency and trust signals without stacking five separate widget apps. Trade-off: used heavily and dishonestly, fake scarcity and permanent countdown timers erode the trust the reviews just built, so switch on the signals that are true for your store and leave the rest off.

A note on that last point, because it decides whether this category helps or hurts. A stock counter that says “only 3 left” when there are three hundred is not a growth tactic, it is a reason a returning customer stops believing you. The Spiegel data is a clue here too: purchase likelihood peaks at ratings around 4.2 to 4.5 stars, not a suspicious 5.0, because shoppers read a wall of perfection as fake. Use these tools to tell the truth faster, not to invent one.

If the job is raising average order value

Every extra pound on the average order drops almost straight to your margin, because you have already paid to acquire the customer and the traffic. On a store that is already converting well, this is often the fastest lever left, which is why upsell apps earn their place.

ReConvert. The post-purchase specialist and the default for thank-you-page offers, at 4.9 across more than 4,500 reviews. ReConvert owns the moment right after checkout, when the customer has already bought and their guard is down, with the best thank-you-page editor on Shopify plus one-click upsells and post-purchase funnels. It starts at 4.99 US dollars a month with a small revenue share. Best for: capturing a second, frictionless order in the seconds after the first. Trade-off: the revenue-share model means the app takes a cut as it works, so read the pricing against your volume.

Selleasy. The value cross-sell pick, at 4.9 across more than 2,400 reviews. Selleasy runs frequently-bought-together bundles and in-cart cross-sells across the whole journey, with a free tier up to 50 orders a month, then 8.99 US dollars a month to 500 orders and 16.99 above that. Best for: stores that want Amazon-style “buy it with” offers cheaply. Trade-off: it is a solid, unflashy cross-sell tool rather than a personalisation engine, so recommendations are rules-based unless you turn on its AI features.

Rebuy. The premium, AI-driven option for stores with the volume to justify it. Rebuy rates around 4.8 across roughly 800 reviews and personalises recommendations across cart, checkout and post-purchase using your store’s own data. It starts at 99 US dollars a month and scales with order volume, with higher tiers running into the hundreds. Best for: larger stores where smarter, data-led recommendations beat simple rules and the maths clears the higher fee. Trade-off: it is the expensive end of this category, and some recent reviews question the value at the top tiers, so measure the incremental revenue against the bill rather than assuming it pays for itself.

The discipline that matters across all three: an upsell only helps if it lands after the customer has decided to buy, or offers something that genuinely complements the order. An aggressive upsell shoved in front of an undecided shopper can cost you the original sale, so measure basket size and conversion together, not basket size alone.

If the job is recovering the carts you’re losing

This is the largest pool of nearly-money in most stores, and the numbers are not close. The Baymard Institute, which aggregates roughly fifty separate studies, puts the average documented cart-abandonment rate at 70.22%, a figure that has barely moved from around 70% in over a decade. Seven in ten people who liked your product enough to add it to the cart then left. A recovery flow is how you get some of them back, and it is usually the highest-return app a store can run.

Klaviyo. The category standard for ecommerce email and SMS, rated around 4.5 on the Shopify App Store. Klaviyo has the deepest segmentation and automation in the category, with abandoned-cart, browse-abandonment and post-purchase flows that use your full Shopify data, and it is free up to 250 contacts. Best for: stores ready to run lifecycle marketing properly, where segmentation and flow logic earn their keep. Trade-off: the bill compounds as your list grows, and the platform rewards a store with someone to actually run it, so a solo founder can end up paying for depth they never use.

Omnisend. The friendlier, better-value alternative for smaller teams, at 4.8 across more than 2,600 reviews. Omnisend covers email, SMS and pop-ups with pre-built ecommerce automations including cart recovery, a genuine free plan for up to 250 contacts and 500 emails a month, and 24/7 live chat on every tier including the free one. Paid plans start at 16 US dollars a month. Best for: small and mid-sized stores that want strong automations without Klaviyo’s complexity or cost curve. Trade-off: the segmentation ceiling is lower than Klaviyo’s, so a large, sophisticated programme will eventually feel the limits.

Whichever you pick, the abandoned-cart flow is the one automation to build first. It targets people who have already told you, by adding to the cart, that they wanted the thing. That is the warmest audience you will ever email, and recovering even a slice of Baymard’s 70% is worth more than most front-of-funnel tactics combined.

If the job is turning one-time buyers into repeat ones

The second sale is the cheapest one you will make, because you have already paid to find the customer. Loyalty and referral apps exist to make that second sale more likely, and they matter most once you have enough repeat traffic for the mechanics to bite.

Smile.io. The easiest loyalty programme to launch, and the most popular by a distance, at 4.9 across around 6,000 reviews and more than 100,000 merchants. Smile.io runs points, VIP tiers and referral rewards with a genuinely usable free plan, then Standard at 79 US dollars a month and Growth at 199 for VIP tiers. Best for: stores that want a working points-and-referrals programme live this week without developer time. Trade-off: the useful tiers sit behind the paid plans, and VIP tiers specifically need the 199 plan, so budget for the step up before the programme feels complete.

LoyaltyLion. The data-led step up for established brands, at 4.6 across more than 500 reviews. LoyaltyLion offers deeper segmentation, retention analytics and integrations aimed at brands running loyalty as a serious channel, starting at 199 US dollars a month for the Classic plan. Best for: larger stores, roughly 2 million US dollars in revenue and up, that will actually use the analytics. Trade-off: the entry price shuts out early-stage stores, and below a few hundred orders a month you are paying for headroom you cannot fill yet.

Retention is the last job to fund, not the first. A loyalty programme is a multiplier on repeat purchases, so if you do not yet have a base of customers coming back, you are paying to reward a trickle. Fix capture, conversion and recovery first, then add loyalty when there is a flow of repeat buyers for it to work on.

The lever no app can pull: your offer

Every app above is a multiplier on demand that already exists. Not one of them creates demand. If shoppers are arriving and not buying, and your reviews are fine and your checkout works, no combination of pop-ups, upsells and countdown timers will fix it, because the problem is not the store. It is the offer: the product, the price, the positioning or the proposition.

This is the most expensive mistake I see growing stores make. Sales are flat, so they install a conversion app. It does nothing, so they add another. Six months later they are paying for eleven apps and the conversion rate has not moved, because the thing that was broken was never on the app store. The honest fix is to stop and ask a harder question: do enough of the right people actually want this, at this price, described this way?

You answer that before you spend, not after. Testing an idea against your target audience up front, whether it is a new product, a pack, an in-context price, a hero claim or an ad, tells you which offers are worth pouring apps and ad budget behind and which are quietly going to lose money however well the store is optimised. That is a different job from anything on this page, and it sits upstream of all of it. If you want the method, start with how to test your audience before you spend and the guide to concept testing platforms.

This is the one place my own company fits the problem on the page, so I will name it plainly and keep it honest. TestFeed lets you put a product, pack, price, claim, name or ad in front of your target shopper and get back a purchase-intent read, the shoppers’ reasons in their own words, and a clear next move, in days rather than weeks. We built it working with challenger brands like Bae Juice and Sol Bevi. It is a pre-spend, directional signal, not a sales forecast and not a guarantee, and it does not judge taste, texture or smell, so it will not tell you whether the product is nice to use. What it does well is triage: killing weak offers cheaply so your app stack and your ad budget only ever amplify the ones worth amplifying. Sort the offer out first, then the apps below have something real to multiply.

The hidden cost of the twenty-app stack

There is a reason I keep pushing you toward three to five apps rather than twenty, and it is not minimalism for its own sake. Every app you install adds code to your storefront, and code slows your pages down.

That speed matters more than most merchants think. Deloitte’s Milliseconds Make Millions study, which analysed mobile data across dozens of retail and travel brands, found that improving load time by just 0.1 seconds lifted retail conversions by 8.4% and average order value by 9.2%. Read that the other way round: the tenth app that adds a fraction of a second to your load can quietly cost you more conversions than it wins. A store carrying twenty apps, half of them barely used, is often slower and worse-converting than the same store running five sharp ones.

There are two other costs the lists ignore. The first is money, obviously, because five apps at 30 to 100 US dollars a month is a real line in a small store’s P&L. The second is maintenance: every app is another thing that can break during a theme update, another support queue, another dashboard nobody checks. Apps have a habit of being installed enthusiastically and then left running long after they stopped earning their fee.

So audit ruthlessly. Once a quarter, open your app list and for each one ask whether you can point to the sales it brought in. If you cannot, it is not a growth tool, it is a tax on your load time. Uninstall it. The goal is not the most apps. It is the fewest apps that each do a job you can measure.

The apps other lists get wrong

Two kinds of tool show up on “increase sales” roundups where they do not belong, and knowing why saves you money and page weight.

An analytics suite is not a sales app. Tools like Triple Whale or Polar tell you where your sales come from, and if you are weighing one, the Triple Whale alternatives guide compares them. That is genuinely useful, but it is measurement, not a lever. Knowing your Meta ads underperform does not increase sales any more than a bathroom scale makes you lighter. Buy analytics to decide where to act, then buy the app that acts. Do not confuse the dashboard for the driver.

A store builder or theme is not an app that increases sales. Page builders and premium themes get slipped onto these lists because they touch conversion, but a faster, cleaner theme is table stakes, not a growth tactic, and swapping themes to chase a conversion bump usually costs more in migration pain than it returns. Fix the theme once, properly, then leave it alone and work on the five jobs above.

And a broader warning that applies to this whole category: an app is a tool, not a strategy. The stores that grow are not the ones with the most apps. They are the ones that picked the right offer, then used a small, sharp stack to get the most out of it.

What to install first, by stage

The right stack depends on where your store is, not on what ranked highest. Here is the order I would fund it in.

A new store, still finding its feet. Do not buy a stack yet. Get Judge.me running on its free plan so your first customers build the social proof that lets the next ones trust you, and use free Shopify Forms to start a list. Everything else is premature until you know people want the product. Spend your energy on the offer, and test it before you scale spend behind it.

A growing store with real traffic that converts. Now the apps have something to multiply. Add an email tool, Omnisend or Klaviyo, and build the abandoned-cart flow first, because recovering part of Baymard’s 70% is the biggest quick win available. Then add one average-order-value app, ReConvert or Selleasy, to lift the basket you are already winning. That is four apps, and it will carry most stores a long way.

An established store optimising the margins. Here the premium tools start to pay: Rebuy for personalised recommendations, LoyaltyLion or Smile’s higher tiers for a serious retention programme, sharper capture through Privy. You have the volume to measure each one, so hold every app to that standard and cut the ones that cannot show their working.

Across all three stages the rule holds: add the app when a specific job is your bottleneck, not because a list said it was essential. And keep testing the offer, because the best-optimised store in the world still cannot sell something people do not want.

Frequently asked questions

What is the best Shopify app to increase sales?

There is no single best one; it depends on the job. To capture visitors before they leave, Privy or the free Shopify Forms. To convert browsers, Judge.me for reviews and Hextom for on-page nudges. To raise average order value, ReConvert or Selleasy. To recover carts, Klaviyo or Omnisend. To bring buyers back, Smile.io. Pick by the weakest link in your funnel, not the star rating.

How many Shopify apps do I need to increase sales?

Most stores need three to five, not twenty. One capture tool, one reviews app, one way to raise order value, and one email or SMS tool to recover carts and bring people back covers the jobs that move sales. Every extra app adds page weight and monthly cost, and Deloitte’s research shows even a fraction of a second of extra load time cuts conversions.

What are the best free Shopify apps to increase sales?

Judge.me has a genuinely useful forever-free reviews plan. Shopify Forms is free and native for email capture. Omnisend and Klaviyo both have free email tiers up to 250 contacts. Hextom Ultimate Sales Boost and Selleasy have free plans capped by usage. You can run one app from most jobs at no cost while you prove they earn their keep.

Can Shopify apps actually increase sales?

Yes, but only by amplifying demand that already exists. Apps lift the share of visitors who buy, raise the average order and bring buyers back, so they work when people already want your product. They cannot manufacture traffic or make people want something they don’t. If nobody is buying despite steady traffic, the fix is the offer, not another app.

What Shopify apps increase average order value?

Upsell and cross-sell apps. ReConvert specialises in post-purchase and thank-you-page offers from 4.99 US dollars a month. Selleasy runs frequently-bought-together and in-cart offers with a free tier up to 50 orders a month. Rebuy is the premium AI option from 99 US dollars a month. All three work best on stores already converting well, where a larger basket is the fastest lever left.

The one-line version

Pick the job before the app. Find the weakest link in your funnel, capture, conversion, order value, recovery or retention, install the one app built for that job, and add another only when a second bottleneck earns it. Keep the stack to the few apps you can measure, protect your load speed, and remember that every one of them is a multiplier. Get the offer right first, because no app can sell what people do not want.
