Short answer
If you work on a Mac and want Apple Search Ads popularity for unlimited keywords, get Astro ($9/mo, billed yearly). If you want to start free, start with Marteso. If App Store Connect itself is the pain, try ASO.dev. If you also need Google Play or download numbers, look at AppTweak or Appfigures.
If you want to see which release moved your ranks, use ASO Mochi, which I make: a daily App Store rank tracker for indie iOS developers, $9/mo with a free plan.

The tools, one by one
Astro
$9/mo, billed yearly ($108) · Mac app (macOS 14+). App Store only.
Astro is a Mac app that pulls keyword popularity straight from Apple Search Ads, scores how hard each keyword is to reach the top 10 for, and tracks unlimited keywords with daily rank updates in the 60+ storefronts where Search Ads runs. It also suggests keywords, pulls rivals' keywords and translates them. There's one plan: $108 a year for one Mac license, with 14 days to ask for a refund. Its demand data is better than ASO Mochi's: Apple's popularity numbers are finer than our autocomplete dots.
- Pick it if
- you work on a Mac, want real Search Ads popularity, and don't mind paying for a year up front.
- Skip it if
- you're on Windows, want to check ranks from any browser, or want to pay month to month.
ASO Mochi
$9/mo, billed monthly · Web. App Store only.
ASO Mochi is a daily App Store rank tracker for indie iOS developers. It checks the top 200 for every keyword each day and marks the days you or a rival shipped an update, so you can see which release moved which keyword. Indie is $9/mo (3 apps, 100 keywords each, a year of history, 10 countries per app), Studio is $19/mo, and the first 100 founders can pay $149 once. It's new, made by one person, App Store only, and your rank history starts the day you add a keyword.
- Pick it if
- you ship often and want to know which update, or which post, moved your ranks.
- Skip it if
- you need Google Play, Search Ads popularity numbers, or download estimates for other apps.
Marteso
Free plan. Pro €18 per app a month. · Web. App Store only.
Marteso is a web ASO tool for indie iOS developers. The free Starter plan tracks 2 apps with 50 keywords each in 5 countries, updated daily, with 3 competitors per app. Pro (€18 per app a month, about 17% less billed yearly) adds 500 tracked keywords, 180+ countries, an AI metadata optimizer, a keyword gap report and metadata change history. Its free plan is more generous than ASO Mochi's.
- Pick it if
- you want to start free, or you have one app and want AI help with metadata.
- Skip it if
- you have several apps on a paid plan, since the price climbs with each one.
ASO.dev

Indie adds keyword and competitor rankings, an ASO check and category ranks, with 30 days of history. Google Play keyword ranks are listed as coming soon.
