}Store consoles only show your own apps. Anything about competitors (their download trajectory, their chart movement after a release) means paid ASO tools with seat licenses. Trends API exposes the same class of signal as JSON: downloads and rankings as time series, plus three live chart feeds.
Download estimates come from AppBrain for Android; iOS coverage is chart position via the App Store Top Free and Top Paid feeds. Both are queryable through the same endpoint with the same key.
Track your app's chart position and category movement over time.
Watch a competitor's download trajectory after each release.
