AppStills.Free tools for app developers
Small utilities we built for our own launches. They run entirely in your browser — no sign-up, no uploads, no watermarks.
App Store Listing Grader
Paste your App Store or Google Play link — get a screenshot-by-screenshot conversion grade, plus your listing rebuilt in AppStills templates.
Play Feature Graphic Generator
Drop your app icon, get a store-ready 1024×500 feature graphic — brand colors extracted automatically, four styles, JPEG or PNG. Nothing uploads.
App Icon Generator
Upload one 1024×1024 image, download every iOS, Android and favicon size — with the Xcode Contents.json included.
App Store Fee Calculator
Price in → what you keep after Apple and Google's 15/30% cut, the Small Business Program, year-two subscriptions and VAT.
Need a launch video, not a utility? The AppStills promo video maker turns your App Store screenshots into an animated MP4 from 15 ready-made scripts — free to build and preview with an account. See the promo video maker
Icon done. Now the screenshots.
AppStills designs your whole App Store & Google Play screenshot set in real 3D, exports every required store size in one ZIP — and turns the same screens into a promo video. Free to start.
