AppSupa

AppSupa is market research for people who build mobile apps. It shows which App Store and Google Play apps already make money, and which top apps in a niche are weak enough to beat, so you can pick what to build before writing code.

How it works:
1. Search an app you know, or open a niche.
2. See estimated monthly revenue and downloads for the top apps.
3. Read what users complain about in the leaders' reviews.
4. Check keyword demand and difficulty for each country's store.
5. Decide: build it, skip it, or build the better version.

Features: Opportunities (earning apps scored 0-100 on demand and how beatable the leaders are), keyword research per country, review insights, competitor tracking with daily keyword ranks, and niches, trends and language gaps.

Data: 5.9M App Store and Google Play apps, revenue and download estimates for 590K+ of them, 40+ country stores. Figures are estimates, for comparing markets.

For product and growth teams at small app studios, indie iOS and Android developers, solo founders and ASO consultants. $29/month or $290/year, with a 7-day full refund on the first payment.
