iOS App Store · solo developers
See the market before you build the app.
Not search volume. We show competition saturation and review complaints from real data, then check whether a solo developer can actually build it. The goal is to waste less time.
Weekly report
A handful of iOS opportunities, every week.
Where competition is thin, what reviews complain about, the smallest version a solo dev can ship. No ads, real data only.
This is not a search-volume ranking. Apple does not publish App Store search volume. IndieRadar uses public, legal data (iTunes Search API, public App Store reviews) to show how crowded a space is and what users complain about. Read the limits honestly.

Why we built it
I shipped an app, ran ads, and found people were not even searching for it.
I built a photo cleanup app, shipped it, and ran Apple Search Ads. The global photo cleaner keywords lost hard to giant apps, and only the local Korean term got any taps. We built this so other solo developers spend less on that kind of trial and error.
