SEOWILL Sticky Add To Cart vs Sticky Add To Cart Bar Pro: which sticky cart app fits your Shopify store?

Search the Shopify App Store for "sticky add to cart" and two names keep showing up just below the big cart drawer suites: SEOWILL Sticky Add To Cart and Sticky Add To Cart Bar Pro. Neither one has the thousand-review footprint of the category leaders, and almost nobody has written about how they differ. This page fills that gap. Every price, limit and feature below was checked on the two App Store listings on October 24, 2026, and where a listing stays silent on something, we say so instead of guessing.

Who makes these two apps

SEOWILL Sticky Add To Cart

SEOWILL Sticky Add To Cart is published by CWILL, a developer based in Cary, North Carolina. The app went live on the App Store on November 21, 2019, and for most of its life it was sold under the SEOAnt brand, which is why older tutorials (including the GemPages help center) still call it "SEOAnt Sticky Add To Cart". The listing handle is sticky-cart-and-sticky-add-to-cart-button.

At the time of checking it held a 4.9 rating from 141 reviews, with 95% five-star ratings and two one-star reviews. It carries the Built for Shopify badge. The listing positions it as more than a floating button: it talks about "sticky carts and mini carts", a Quick Buy button, a countdown timer and a cart slider. The admin is available in English, Spanish, Portuguese (Portugal), German and French.

Sticky Add To Cart Bar Pro

Sticky Add To Cart Bar Pro is made by Great Apps Factory, a studio in Ahmedabad, India, that some directories shorten to "The GAF". It is the older of the two: launched June 16, 2017. Its handle is simply sticky-add-to-cart, which tells you how early it arrived in the category.

It shows a 4.9 rating from 42 reviews (41 five-star, one two-star) and also has the Built for Shopify badge. Its pitch is narrow on purpose: a bar that appears when the shopper scrolls past the original button, adapts to the theme automatically, and behaves exactly like the store's own add to cart button. The admin is listed in English only.

Pricing: clicks versus visitors

This is where the two apps part ways most clearly, because they meter usage in different units.

SEOWILL has two plans. The Free plan lists 25 clicks, the automatic one-click install, mobile and desktop responsiveness and 24/7 live chat. The Pro plan costs $7.99 per month, or $71.88 per year (the listing says that saves 25%), and lists unlimited clicks, the sticky add to cart bar, the sticky cart with cart slider and the Quick Buy cart, with a 14-day free trial. The listing does not define what counts as a click or when the counter resets, so treat 25 clicks as a way to test the app rather than a plan to run a store on.

Sticky Add To Cart Bar Pro has four plans, all tied to monthly visitors:

Every paid plan adds "No branding" and every plan includes live support. No free trial is listed, which matters less here because the free tier is usable on a real, small store.

So which one is cheaper? It depends on your traffic. A store under 10,000 monthly visitors pays $3 with Great Apps Factory against $7.99 with SEOWILL. A store above 50,000 visitors pays $10 with Great Apps Factory against $7.99 with SEOWILL, or about $5.99 per month if it takes SEOWILL's annual plan. Both bill in US dollars every 30 days.

Criterion by criterion

The sticky bar itself

Both apps do the core job: keep a buy button on screen once the shopper scrolls. Sticky Add To Cart Bar Pro documents more of the bar's behavior. Its screenshots show a bar at the top and a bar at the bottom of the page, the Free plan lists separate desktop settings and mobile settings, and button animations are included at no cost. The description also stresses that the add to cart action mirrors the default product button, which is reassuring on themes with custom product forms.

SEOWILL's listing describes the bar in broader strokes ("fully customize Sticky Cart to match your store") and does not spell out position options, scroll triggers or animations. That does not mean they are absent, only that you cannot confirm them from the listing. One reviewer from January 2026 mentions customizing colors and display timing, which hints at timing controls, but we would test it during the trial.

Neither listing mentions a variant picker or quantity selector inside the bar. If your catalog depends on shoppers choosing size and color from the sticky bar, install both on a test theme and check before committing.

What sits around the bar

This is SEOWILL's strongest argument. Its Pro plan bundles a cart slider and a Quick Buy cart, and the feature tags on the listing add a countdown timer, a free shipping bar, announcements, promotions and one-click upsell. If you are currently paying for a separate countdown app or a basic shipping bar, SEOWILL can absorb part of that job for $7.99 a month.

Sticky Add To Cart Bar Pro lists cart drawer and sticky cart among its cart display tags, plus announcements, custom rules and skip to checkout, but its description and plans never present a full cart slider or upsell tool. Read it as a focused bar that can send people straight to checkout, not as a cart replacement. If you need a proper slide cart, see how dedicated tools compare in our Kaching Cart Drawer vs Essential Cart Drawer and Sale max vs HS Slide Cart Drawer pages.

Customization and code

Both list custom CSS and custom styles. Great Apps Factory also lists custom HTML, which gives developers a bit more room to inject a badge or a short message. SEOWILL lists custom rules and custom CSS. For a merchant who never touches code, both rely on visual settings; for an agency, Great Apps Factory's HTML option is a small plus.

Tracking and integrations

Both apps connect to Google Analytics. SEOWILL goes further on paid social tracking, listing Facebook Pixel, Pinterest and Snapchat in its "works with" section, plus Shopify Admin. Great Apps Factory lists only Shopify Admin there, with Google Analytics mentioned in its highlights. If you run Meta or Pinterest ads and want sticky bar clicks to feed those pixels, SEOWILL documents it and its rival does not.

SEOWILL is also documented by GemPages, whose help center explains that the app works with GemPages pages without a separate widget (version 7 recommended). That matters if your product pages are built with that page builder. We found no equivalent page builder documentation for Sticky Add To Cart Bar Pro.

Languages and multi-currency

Great Apps Factory says the bar automatically supports multiple currencies and languages on the storefront, which suits stores selling across markets. Its admin, however, is English only. SEOWILL offers its admin in five languages but its listing does not make the same storefront multi-currency claim. Different strengths: one is easier to manage for non-English teams, the other states storefront coverage more clearly.

Support and reviews

Both apps have the same 4.9 average, and in both cases support is the top theme in reviews. SEOWILL's reviews from 2025 and 2026 repeatedly praise quick fixes over live chat, and the developer replies to some reviews. The one clearly negative review on its first page (July 2023) describes a billing glitch after an upgrade, which the developer says was fixed.

Great Apps Factory reviewers mention custom features built within hours and fixes on public holidays. Recent reviews from September 2026 show the app is still installed and supported, though no developer replies appear on the first review page. The sample is smaller: 42 reviews against 141.

Three stores, three choices

A new store on a tight budget

A candle shop doing 3,000 visits a month wants a bottom bar on mobile and nothing else. Sticky Add To Cart Bar Pro covers it for free up to 500 visitors and for $3 a month beyond that, with no branding. SEOWILL's 25-click free tier would run out quickly, and $7.99 buys features this store does not need yet. Great Apps Factory is the logical pick.

A mid-size brand running paid social

A supplement brand at 40,000 visits a month runs Meta and Pinterest ads and launches weekly flash sales. SEOWILL makes more sense: the countdown timer supports the flash sales, the pixel integrations are listed, and the cart slider plus Quick Buy cart shorten the path to checkout. At $7.99 (or $71.88 a year) it costs less than Great Apps Factory's $5 Plus plan would cost once you add a separate countdown app.

A high-traffic store with a cart app already installed

An apparel store above 50,000 visits already uses a full cart drawer and a reviews app. It only wants a clean, theme-matched bar that never fights with its existing cart. Both apps work, but Great Apps Factory's narrow scope reduces the risk of overlapping features, while SEOWILL is $2 cheaper per month at unlimited usage. Install both on a duplicate theme, check variant handling and how each interacts with the existing drawer, then decide. Our guide on adding a sticky cart button to Shopify lists what to test.

Switching from one to the other

Neither app stores product data that needs exporting. A sticky bar reads the product page it sits on, so migration is mostly about settings and cleanup.

From Sticky Add To Cart Bar Pro to SEOWILL

1. Note your current colors, button text, position and animation choices.
2. Install SEOWILL and start the 14-day Pro trial so the bar and cart slider are available.
3. Enable the app embed in the theme editor and switch on the widget in the Sticky Cart section, as the GemPages setup guide describes.
4. Disable Sticky Add To Cart Bar Pro before uninstalling, then check a product page on mobile to confirm only one bar shows.
5. If you used custom HTML in the old app, rebuild that message with SEOWILL's announcement or custom CSS options.

From SEOWILL to Sticky Add To Cart Bar Pro

1. List what you used beyond the bar: countdown timer, cart slider, shipping bar, pixels. Great Apps Factory will not replace those, so plan another tool for each one you still need.
2. Install Sticky Add To Cart Bar Pro and pick the plan matching your monthly visitors.
3. Set desktop and mobile settings separately, then choose top or bottom placement.
4. Cancel SEOWILL's subscription in the app, remove its app embed, and test checkout on a live product.

In both directions, test on a duplicate theme first, and run each bar for at least two weeks before judging the effect on add to cart rate. If you are comparing this category with other options, our STKY vs Buy Me page covers two more sticky bar apps, and the VR Urgency Countdown Timer vs Countdown Timer Bar Samita page helps if the countdown is the part you care about most.

What we could not confirm

Small apps have short listings, so a few gaps remain. SEOWILL does not define what a "click" is on its Free plan, and does not list position options or animations. Sticky Add To Cart Bar Pro does not list a free trial, a variant selector or developer replies on its first review page. Neither lists a quantity selector in the bar. These are the points to test yourself before you rely on either app during a big sale.
