Simple Cycle. vs Holsi

A period tracker built for women who refuse to send their cycle to the cloud. Local-only. No account. No subscription. Nothing leaves your phone. Ever. Open the app, log your day, close it. Open it again when you need to. The cycle stays here, predictions get smarter as you log, and nobody — not us, not Apple, not your phone carrier, not advertisers — sees a single byte of it. What you get: • Cycle calendar with period dots and a passive fertile-window indicator • Predictions that learn from your own logs — more cycles, sharper predictions • Quick logging — flow, cramps, mood, optional notes • Face ID / Touch ID app lock • One period reminder, one day before — or off • Full CSV export, anytime, no questions What you don't get: • No accounts. No login. Ever. • No iCloud sync. No Apple Health sync. No cross-device anything. • No ads. No analytics. No trackers. • No subscription. No upsells. No "premium tier." • No streaks, badges, or daily check-in nagging. • No symptom mining. No AI "cycle coach." The deal: Free for 7 days. Then $1.99, once — yours forever. No subscription. No price hike. The lowest one-time price on the App Store for a serious period tracker, and the only one that physically cannot leak your data because it's never connected to anything. The fertile-window indicator is estimated from cycle averages and is not a contraceptive — not for family planning. Built by Under5 — apps that respect your time, your privacy, and your wallet.
