The best sticky add to cart app is often none at all: check your theme first.
Maestrooo's Prestige, Impact and Focal themes ship with a "Show sticky add to cart" setting that's on by default.
If your theme lacks one, EA Sticky Cart Drawer & Upsell (free plan, 4.8 stars from 217 reviews) and Uplinkly Sticky Cart (free plan, 9 dollars a month for Pro) are the simplest add-ons.
If you already pay for a page builder, 
GemPages has a ready-made sticky add-to-cart element.
How we picked: we read each vendor's docs, pricing pages and app store listings in November 2026, and compared them against the sticky add-to-cart tests in our archive. We have not used these apps ourselves.

The 9 best sticky add to cart apps
1. Your theme's built-in sticky add to cart
Best for: Shopify sites already on a theme that has the setting, which costs nothing extra and adds no app code.
What it does: Maestrooo says Prestige, Impact and Focal offer a sticky add-to-cart feature on product pages, switched on by default.
You turn it off in the theme editor under Products, Default template, Product page section, "Show sticky add to cart".
Many other paid themes include something similar, so check your product page section settings before you install anything.
Key features:
- Built into the theme's product section, styled to match the rest of the page
- One toggle per product template, so you can turn it off on complex products
- No extra script loading on every page
Pros:
- No monthly fee and no app to uninstall later
- Updates with the theme, so it's less likely to break
Cons:
- Few design options compared with a dedicated app
- Not available everywhere: Shopify's free Horizon theme lists a sticky header and quick buy but no sticky add-to-cart bar
- Maestrooo itself says you "might prefer turning off this feature" if your products are complex
Pricing: Included with the theme. On the Shopify Theme Store, Prestige and Impact cost $400 and Focal costs $320, one-time.
Rating: Prestige has 91% positive from 875 reviews, Focal 93% positive from 335, and Impact 85% positive from 200 on the Shopify Theme Store.
In our archive: UN/COMMON added a sticky add-to-cart button to Ursa Major's mobile product pages and got +5.1% revenue per visitor.
A built-in setting gets you the same basic bar for free.

The Pro plan adds cart upsells, a free shipping rewards bar, free gifts and A/B testing.

Pros:
- The sticky bar is on the free plan
- Has the Built for Shopify badge

- If your theme or another app already runs your cart drawer, you'll be paying for features you can't use
Pricing: Free plan; Pro $9.99/month with a 7-day trial, per the Shopify App Store listing.
Rating: 4.8 from 217 reviews on the Shopify App Store.
In our archive: GrowthRock tested a mobile sticky button that opened a slide-up buy drawer and got +5.2% orders.
That pairing of sticky button and drawer is what this app sells.

In our archive: A sticky add-to-cart bar on Aeromotive's desktop product pages lifted revenue per visitor by 69% in a Blend Commerce test.
Blend didn't share sample size or confidence, so treat the size of that number with care.
4. Ultimate Sticky Add to Cart
Best for: Sites that want a Buy Now button that skips the cart, plus full ad-pixel tracking.
What it does: Conversion Bear's app adds a floating add-to-cart button on every product page at any screen size.
It can send shoppers straight to checkout and fires events to the main ad pixels.
Key features:
- "Buy Now" option for direct checkout
- Facebook, Google Analytics, Pinterest, Snapchat and TikTok pixel events
- Custom CSS and JavaScript

Rating: 5.0 from 8 reviews on the Shopify App Store.
In our archive: Clean Commit's sticky mobile add-to-cart button with the price on it lifted add-to-cart by 3.9% for AFTCO. A plain bar is often enough.
6. Vitals
Best for: Sites that would otherwise install several small apps (reviews, bundles, sticky bar, wishlist).
What it does: Vitals bundles more than 40 tools into one app, including a sticky add-to-cart button, product reviews, bundles and upsells, wishlists and visitor recordings. You pay by monthly order volume.
Key features:

It has a Sticky Add-to-Cart element that comes with product, variant, quantity and add-to-cart parts, which you drag onto a page.

- Layout settings in the sidebar
- A/B testing through the GemX add-on
Pros:

In our archive: Dave Diederen's sticky bar that scrolls shoppers back up when a variant or bundle must be picked earned +$32,565/month revenue.
A builder makes that kind of custom behavior easier to set up.
8. PageFly
Best for: Sites already building pages in PageFly.
What it does: PageFly is a Shopify page builder.
It doesn't have a single sticky add-to-cart widget.

- Cart drawer with upsells (beta)
Pros:

- Only applies to PageFly-built pages
Pricing: Free; Builder $24/month; Accelerate $99/month; Enterprise $299/month (Shopify App Store).
PageFly has an affiliate program, so we may earn a commission if you sign up through our links.

If you run SaaS or lead gen pages on WordPress, a sticky CTA bar is the equivalent test.
Which one is right for you
You're on Prestige, Impact, Focal or another theme with the setting
Use the built-in setting. Spend the app budget on an A/B testing tool such as 
Shoplift or 
Intelligems so you can find out whether the bar helps your site.
Your theme has no sticky bar and you want it free
EA Sticky Cart Drawer & Upsell or Uplinkly Sticky Cart.
Both put the bar on their free plan.
You build pages in a page builder
GemPages if you want a ready-made element, PageFly if you're already on it and don't mind setting up a sticky section.
You're replacing a pile of apps
Vitals, but only if you'll use several of its modules.
You run WooCommerce, SaaS or lead gen pages
WPC Sticky Add To Cart for WooCommerce. On a non-store site, a sticky CTA bar built in your theme or landing page builder does the same job.
What to look for in a sticky add to cart app
- Variant handling: the bar should either include a variant picker or scroll shoppers back to choose, so nobody adds the wrong size.
- Separate mobile and desktop settings: results in our archive differ by device, so you want to control each one.
- When it appears: the bar should show only after the main button scrolls out of view.
- Theme fit: it should pick up your fonts and colors and not cover chat widgets, cookie banners or the cart drawer.
- Script weight: fewer scripts are better; a theme setting adds none.
- Price on the bar: showing the price beside the button saves shoppers a scroll.
- Easy to switch off per template: complex products may do better without it.
- Testable: make sure your A/B testing tool can show the bar to one group and hide it from the other.
Real test results: sticky add to cart
Most sticky add-to-cart tests in our archive won, but not all.
Here are the clearest results, including two where more carts didn't turn into more sales.
See all of them on our sticky add-to-cart element page.
@DaveDiederen
Blend CommerceBlend Commerce
Clean CommitClean Commit- Dave Diederen's sticky bar that scrolls back to the main buy box: +17.39% revenue per visitor.
- PerTronix's desktop sticky bar won +25.95% conversion rate, while the mobile version was flat: +10% conversion, not significant (Blend Commerce).
- Clean Commit's sticky bar lifted desktop add-to-cart 45.3%, but sales fell. Another mobile sticky button got +6.8% adds and -7.7% conversion rate.
- Blend Commerce removed the sticky bar and early buy buttons on a Dr Pooper page that needed explaining, and conversion rose 6%. That result reached only 76% significance.
The lesson: a sticky bar makes adding to cart easier.
It doesn't answer a shopper's questions. Test it on your own traffic with one of the Shopify A/B testing apps, and judge it on orders or revenue per visitor, not add-to-cart rate.
Watch out for
- Doubled bars: if your theme already has a sticky bar, a second one from an app stacks on top of it. Turn one off.
- App stacking and page speed: every app adds script. If you already run a cart drawer, upsell and reviews app, pick a sticky option that's built into one of them or into the theme.
- Covering other things: on mobile, bottom bars can cover chat bubbles, cookie banners and express checkout buttons. Check on a real phone.
- Fake urgency: several apps add countdown timers to the bar. A timer that resets on every visit damages trust; only use it for a real deadline.
- Skipping the variant step: a bar that adds the default size without asking leads to wrong orders and returns.
