Monitoring tools for things that only exist in the present tense.

App Store ranks are not published retroactively. Neither are most search results, price lists, or availability tables. If nobody wrote today's number down, today is gone. My Actors write it down, keep the series, and tell you when it moves.

Official endpoints only. No headless browsers pretending to be people, no undocumented internal APIs that vanish on a Tuesday.

Errors travel with their numbers. Where a figure is derived rather than observed, the margin ships alongside it, and alerts only fire when the signal survives that margin. A number without its error is a number that will eventually lie to you.

Silence is treated as a fault. A run that succeeds with an empty dataset is worse than one that fails, because nobody investigates a green check. My Actors fail loudly and write the reason where you will actually see it.

No personal data. Reviewer names, author handles, and profile details are not collected, not stored, and not resold.

• App Store Rank & Rating Watch — daily keyword ranks, and an alert when new ratings turn against you.

More coming. If one of them breaks, open an issue on the Actor — I read them.
