Detailed comparisons
PinkyBloom vs Flo
Flo is the world's most popular period tracker — and the subject of a $56M class action settlement for sharing menstrual data with advertisers. PinkyBloom gives you smarter AI insights with zero-knowledge architecture: your data never leaves your iPhone, period.
PinkyBloom vs Clue
Clue is a well-designed, science-backed period tracker based in Berlin with strong GDPR compliance. But it still stores your data in the cloud and charges $39.99/yr for premium features. PinkyBloom keeps everything on your iPhone with more powerful AI — for free.
PinkyBloom vs Natural Cycles
Natural Cycles is an FDA-cleared contraceptive app that requires daily temperature readings and costs up to $149.99/yr. PinkyBloom delivers smarter cycle intelligence with on-device AI, no hardware requirements, and no subscription — completely free.
PinkyBloom vs Ovia
Ovia Health is owned by Labcorp and shares user data with employers and health plans. Mozilla gave it a 'Privacy Not Included' rating. PinkyBloom's zero-knowledge architecture ensures your reproductive health data stays on your device — never shared with your employer or anyone else.
PinkyBloom vs Stardust
Stardust surged in popularity after Roe v. Wade with privacy promises, but a Privacy International investigation found concerning data practices. PinkyBloom offers provable privacy through on-device architecture — not just promises.
PinkyBloom vs Glow
Glow suffered a data breach that exposed 25 million users and stores data on AWS by default. Its opt-in 'Offline Data Protection' mode acknowledges the problem but doesn't solve it. PinkyBloom is private by default — not as an afterthought.
PinkyBloom vs Period Tracker
Period Tracker by GP Apps is one of the oldest and most downloaded period trackers with 250M+ downloads. But it's a basic logging tool from a different era. PinkyBloom brings on-device AI, voice logging, mood forecasts, and zero-knowledge privacy to replace simple calendar tracking.
