AppSupa helps you decide which mobile app to build. Search an app or open a niche to see estimated monthly revenue and downloads for the top apps, read what users complain about in the leaders' reviews, and check keyword demand and difficulty by country. It also offers opportunity scoring, competitor tracking and daily keyword ranks. All revenue and download figures are estimates. Paid subscription with Pro at $29 per month or $290 per year.
AI tools made building an app fast, and that moved the hard part to choosing what to build. I kept seeing developers spend months on apps nobody searched for, while plain utilities with weak, outdated leaders quietly earned good money. The data to spot those gaps existed, but only in enterprise tools priced for big studios. AppSupa puts it in reach of a solo developer, so you can start from an app that already earns and see exactly where its leader is weak.
