Five apps. Each one owns a different moment.
Bundles on the product page, a cart drawer, a shipping bar, one popup, and edits after checkout. Install the one that matches the leak.

Example notifications
The basket gets heavier at five moments.
Each app owns one of them. A second install adds a different moment. It does not repeat the first.
On the product page
Addly
Quantity breaks, frequently bought together, mix and match, and add-ons. Offers can be drawn from real orders. Every paid plan has the same features.
In the cart
Addy
An AI cart drawer with in-cart upsells, volume tiers, gifts, shipping protection, a progress bar and a delivery date. A different drawer per market or tag.
On the way to free shipping
Goalify
A bar and an embeddable widget. Stack a gift, shipping and a discount, set the threshold per country, and test the bar. AI upsells close the gap.
When they hesitate
Monet
One popup, on add to cart, at checkout start, or on exit. Bundles, cross-sells, add-ons, and discounts including BOGO. It does not collect emails.
After they pay
Reviso
Shoppers change the address, the shipping method, variants, quantities and items before fulfilment. A cancel can be met with a discount or a gift.
From the App Store
Three notes from the listings. Ratings and the rest of the reviews sit on Shopify.
We love the app, it definitely increases our monthly revenue.

I really like that I can add upsells, a free shipping bar, delivery estimates and discounts all in one place instead of using multiple apps.

One candle, told as a receipt.
An example, not a case study. The jobs are real. The prices are a story, not a measured lift.

Paste a URL. Get the leak, then the app that owns it.
The audit reads the product page and the cart the way a shopper does. Password-protected stores work. No Shopify admin login. Each miss points at one app, not the whole suite.
Which one first
Pick by the moment. A second app later adds a different moment. It does not repeat the first.

Questions merchants ask
How do I increase average order value on a Shopify store?
Add one offer at each high-intent moment: a bundle or quantity break on the product page, an upsell and a free-shipping goal in the cart, a single targeted popup at add-to-cart or exit, and a post-purchase offer after payment. Start with the moment where your funnel leaks most, measure for two weeks, then add the next.
Which Ninety9 app should I install first?
If shoppers buy one item at a time, start with Addly for bundles and quantity breaks on the product page. If carts are abandoned or small, start with Addy (AI cart drawer) and Goalify (free shipping progress bar). If you want one well-timed offer without touching the theme, start with Monet. If support is drowning in order changes, start with Reviso.
Do the Ninety9 apps work together?
Yes. Each app owns a different moment in the buying journey — product page, cart, checkout intent and post-purchase — so they stack without showing duplicate offers. You can install one and get the full benefit, then add another later.
Are Ninety9 Shopify apps free?
Every app has a free plan or is free to install. Where paid tiers exist they are billed through Shopify, start from a few dollars a month, and step up with your store’s monthly order volume.
Will these apps slow down my Shopify store?
No. Each app is a Shopify theme app extension: it loads asynchronously, stays out of the Largest Contentful Paint path, makes no edits to theme.liquid and uninstalls cleanly. You enable it from Online Store → Themes → Customize → App embeds.
Do I need a developer to set up upsells or a cart drawer on Shopify?
No. Install from the Shopify App Store, switch the app embed on in the theme editor and configure offers in the app. Most merchants are live in under ten minutes, and support replies from a developer, not a script.
How do I find out what is wrong with my Shopify product page?
Run the free CRO Audit for Shopify stores (https://ninety9.dev/cro-audit/). Paste your store or product URL and it checks the product page and cart the way a shopper sees them, ranks what stops the sale, and names the fix. No login and no card required.
Start with one app, free
Every Ninety9 app has a free plan and installs in a couple of minutes. Pick the moment in your funnel that leaks the most and fix it first.
Every app installs from the Shopify App Store. No theme code, no developer needed.
