When I try to type in a question, the letters disappear. I keep trying and they keep disappearing. So I give up.

Questions this record can answer

How was every figure on this page produced?

Each figure is read from public App Store metadata or computed from it, dated to when we read it, and traceable to a stored row. Percentiles, cadence, longevity and sentiment are derived by us; ratings, prices, sizes and dates are taken as the store reports them.

Why can the star average and recent opinion disagree?

The star average is cumulative over the app’s whole life, so recent opinion barely moves it. Any sentiment figure we compute reads only recent review text, which is why it turns first. Treat a divergence as an early indicator, not a verdict.

What can this page not tell you?

Downloads, revenue, active users, subscription pricing inside the app, and anything about security or data handling. None of those are visible in public store metadata, so we do not estimate them.
