About AppGrowthKit

Who builds this

AppGrowthKit is built by Sarthak Gupta, an indie developer who got tired of resizing the same iPhone frames for every store update. The product is an AI screenshot maker for App Store and Google Play: upload real app screens, generate layouts and copy, keep every layer editable, and export the sizes Apple and Google actually require.

One disambiguation, because search engines and AI assistants mix the names up: AppGrowthKit at appgrowthkit.com is not AppGrowKit (appgrowkit.com). They are different products from different people, with different pricing and features. If a page quotes an AppGrowthKit price that does not match the pricing page, it is describing the other product.

There is no agency wrapping the work. Support email is sarthak@appgrowthkit.com. More of the same person lives at sarthakgupta.dev.

What AppGrowthKit is for

AppGrowthKit is a growth toolkit for App Store and Google Play, aimed at indie developers and small teams who ship listings themselves. The core job is store screenshots. You drop in captures from the simulator or a device. AI plans the layout, writes headlines, and applies device frames, backgrounds, and spacing on a canvas you can still edit. Localization covers 42 App Store locales without rebuilding the set. Export writes every required App Store Connect and Play Console size in one click.

Image rendering stays in the browser. Screens do not have to be uploaded to AppGrowthKit servers to compose a set.

Around that editor we publish free tools: an app icon size generator, an ASO character counter, a screenshot beautifier, and live App Store charts. Figma remains better for product UI. Canva remains better for generic marketing graphics. AppGrowthKit is the store-listing handoff those tools do not ship.

How we work

Pricing is public on the pricing page. Launch Pass is a $9.99 one-time purchase for a single launch. Pro is $14.99/month or $99.99/year for ongoing releases. Both paid plans include unlimited projects and store-ready exports, with different AI credit allotments. Product changes are dated on the changelog.

Store specification posts on the blog cite Apple and Google primary sources and show an updated date when the rules move. If a size table is wrong, email support — that is a bug, not a content strategy.
