Overview
Flo ja Period Calendar Simple Design'i poolt on allalaadimiste arvu järgi kaks kõige populaarsemat menstruatsioonirakendust, mis kunagi loodud. Flo väidab, et tal on 440 miljonit kasutajat; Period Calendar väidab, et tal on 300 miljonit. Koos esindavad nad peaaegu kolme neljandikku miljardist kontost, mis jälgivad reproduktiivtervise andmeid.
Rakendused on lähenemisviisis dramaatiliselt erinevad. Flo on ulatuslik terviseplatvorm, millel on AI vestlusrobot, kogukonna foorumid, ekspertide sisu ja premium tellimused. Period Calendar on lihtne, ilma liigsete funktsioonideta jälgija — logige oma menstruatsioon, vaadake ennustusi, jälgige sümptomeid. Flo sihib kaasatud tervise tarbijat; Period Calendar sihib kasutajat, kes soovib lihtsust üle kõige.
Mida nad jagavad, on privaatsuse lõhe. Flo privaatsus on dokumenteeritud föderaalses kohtus. Period Calendar'i privaatsus on sisse ehitatud selle ärimudelisse — väites, et ei kogu andmeid, samal ajal kui käivitab Google'i reklaamimise SDK-sid, mis koguvad andmeid disaini järgi.
Privacy comparison
Flo's privacy failures are the most documented in the industry. An FTC order in 2021, a class action Flo settled for $8M in 2025, and a California jury verdict against Meta for eavesdropping on Flo users' data. Flo denies wrongdoing, and no court has found that it broke the law.
Period Calendar's privacy situation is different but concerning. The app markets itself with bold "we don't collect or store your data" claims. But it's ad-supported through Google Ads, DoubleClick, and AdMob. Privacy International documented heavy third-party network traffic to Google advertising services despite the local storage claims. Advertising SDKs collect device identifiers, usage patterns, and behavioral data by definition — that's how ad targeting works.
The pattern is the same: both apps say one thing about privacy and do another. Flo's contradiction ran for nearly three years before the press caught it. Period Calendar's contradiction is structural — you cannot simultaneously claim "no data collection" and run ad networks that require data collection to function.
PinkyBloom eliminates the contradiction. No ads means no ad SDKs. No accounts means no identity linkage. Your cycle log is stored on your phone, protected by your phone's own encrypted storage.
Features and intelligence
Flo on funktsioonirikas: 70+ sümptomit, AI vestlusrobot, kogukonna foorumid, raseduse režiim, sisu 120+ meditsiini eksperdilt. See on terviseplatvorm, mitte lihtsalt jälgija.
Period Calendar on funktsiooniliselt lihtne: menstruatsiooni logimine, ovulatsiooni hinnangud, sümptomite jälgimine ja kalendrinägemine. Tasuline versioon eemaldab reklaamid. See on logimisvahend, mis teeb põhiasjad usaldusväärselt.
Kahte võrreldes pakub Flo selgelt rohkem. Kuid Flo funktsioonid tulevad koos pilve töötlemise, tellimuste ja dokumenteeritud privaatsuse rikkumistega. Period Calendar'i lihtsus tuleb koos reklaamide ja vananenud arhitektuuriga.
PinkyBloom pakub Flo tasemel võimalusi — AI assistent, meeleolu ennustused, tervisehoidla, arsti raportid — koos Period Calendar'i tasemel lihtsusega — konto pole vajalik, töötab kohe. Hääle logimine tähendab käed-vabad jälgimist ilma käsitsi menüüta.
Pricing comparison
Flo charges ~$49.99/year for premium. Period Calendar is free with ads and optional paid upgrades. The cost difference is significant — Flo is among the most expensive period trackers; Period Calendar is among the cheapest.
But the real cost includes what you pay beyond money. Flo costs subscriptions and, for nearly three years, your data. Period Calendar costs your attention (ads) and potentially your data (ad SDKs).
No ads, no hidden data costs. More features than Flo, simpler than Period Calendar, and never sold.
There's a better option
The two most-downloaded period trackers both have privacy contradictions — Flo's documented by the FTC, Period Calendar's embedded in its ad model. PinkyBloom is the zero-contradiction alternative: no ads, no account, never sold. More features than Flo, simpler setup than Period Calendar.
