LunaLock is the period tracker that actually keeps your data private. No cloud sync. No accounts. No data collection. Your period data stays on your device, period. Unlike other period apps that upload your most personal health data to remote servers, LunaLock was built from the ground up with one principle: your data never leaves your phone. FREE FEATURES: - Log period start and end dates with haptic feedback - Smart cycle prediction with confidence ranges (not just averages) - Track 6 common symptoms: cramps, bloating, headache, fatigue, acne, mood swings - Log your daily mood with 6 mood options - Record flow level from spotting to heavy - Calendar view with period and prediction markers - FaceID and PIN lock with emergency shake-to-lock - Auto-lock timer for extra security - Period reminders with customizable advance notice - Onboarding privacy promise - Delete all data anytime - No ads, no accounts, no tracking PRO FEATURES (one-time $3.99 purchase): - Trend charts for cycle length, symptom frequency, and mood patterns - Data export as PDF for doctor visits or JSON for other apps - Home screen widget with countdown and cycle day - 5 beautiful color themes (Luna, Rose, Ocean, Forest, Sunset) - HealthKit write-only integration (optional) - Monthly and annual cycle reports - Emergency shake-to-lock - All future updates included WHY LUNALOCK? Other period apps like Flo and Clue require accounts, collect your data, and use subscriptions. LunaLock is different: - $3.99 once, not $4.99/month forever - Zero data collection - we literally cannot see your data - FaceID lock means even someone borrowing your phone cannot see your period info - Emergency shake-to-lock for when you need instant privacy LunaLock. Your period. Your phone. Nobody else's.

Verdict

The call

LunaLock and Cove are too close to call on the numbers: across 5 compared parameters โ€” price, ads, in-app purchases and device support among them โ€” neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. LunaLock sells 1 one-off in-app purchase and Cove sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
