How hard is “cycle tracker”?
Real, Apple-confirmed search demand (High). Apple fills the top ten for almost every search, so a full board says nothing yet — we haven't checked how many of these apps are genuinely about it. Until we have, this is neither open nor contested.

Subscribers needed for a target MRR
Type in prices you’ve actually seen on a competitor’s paywall — this repo has no way to scrape subscription tiers, only the App Store’s public data. Monthly and annual plans are normalised so they can be compared honestly.
5% is a commonly-cited starting point for a consumer subscription app — not measured against this niche. Edit it.
Positions come from Apple’s public Search API — the top 25 are stable enough to read as a ranking, and an app missing from this table is outside the first ~190 results rather than absent from search. Ratings and chart ranks are the same numbers Apple shows anyone. Nothing here is a prediction.
