ASOFAST

ASOFAST is a tool for app developers who dread the manual grind of App Store Optimization. Instead of writing titles, subtitles, and descriptions by hand for each market, you paste your app store link, pick your competitors, and let the AI generate a full listing — copy, translations, and localized screenshots — in one go. It supports both Apple's App Store and Google Play, covering up to 87 locales. The output is formatted to fit each store's character limits and ready to copy into your console.

How it works is straightforward: you add your app, select up to five competitors for keyword analysis, import your existing screenshots, choose your target languages (up to 87 at once), and hit generate. The AI writes optimized ASO copy, translates it into native-sounding text for each market, and renders your screenshots with localized captions — without redesigning your layout. You can preview everything before publishing, and nothing goes live until you say so. The tool uses a credit system: one credit generates one language of a listing or one language of screenshots. Credits never expire, and there's no subscription — you buy a pack and use it when you need it.

ASOFAST is built for indie developers and small studios who want to rank higher and convert better in multiple countries without hiring an agency or a designer. It's especially useful if you have apps in niche markets where competitors haven't bothered to localize. The free signup gives you six credits to try (enough for three complete languages), and the paid packs start at €9 for 25 credits. If you manage multiple apps, the Studio pack at €79 for 300 credits offers the best value.
