Overview
Flo un Period Calendar no Simple Design ir, pēc lejupielāžu skaita, divi populārākie menstruāciju izsekošanas rīki, kas jebkad izveidoti. Flo apgalvo, ka tam ir 440 miljoni lietotāju; Period Calendar apgalvo, ka tam ir 300 miljoni. Kopā tie pārstāv gandrīz trīs ceturtdaļas miljardu kontu, kas izseko reproduktīvās veselības datus.
Šie rīki ir dramatiski atšķirīgi pieejā. Flo ir visaptveroša veselības platforma ar AI čatbotu, kopienas forumiem, ekspertu saturu un premium abonementiem. Period Calendar ir vienkāršs, bez liekām funkcijām izsekošanas rīks — pierakstiet savu menstruāciju, skatiet prognozes, izsekojiet simptomus. Flo mērķē uz aktīvo veselības patērētāju; Period Calendar mērķē uz lietotāju, kuram vienkāršība ir vissvarīgākā.
Ko viņi abi dalās, ir privātuma plaisa. Flo privātuma problēmas ir dokumentētas federālajā tiesā. Period Calendar privātuma problēmas ir iekļautas tā biznesa modelī — apgalvojot, ka nenodrošina datu vākšanu, kamēr darbojas Google reklāmas SDK, kas pēc definīcijas vāc datus.
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 ir bagāta ar funkcijām: 70+ simptomi, AI čatbots, kopienas forumi, grūtniecības režīms, saturs no 120+ medicīnas ekspertiem. Tā ir veselības platforma, nevis tikai izsekošanas rīks.
Period Calendar ir vienkāršs funkciju ziņā: menstruāciju pieraksts, ovulācijas novērtējumi, simptomu izsekošana un kalendāra skats. Apmaksātā versija noņem reklāmas. Tā ir pieraksta rīks, kas uzticami veic pamatus.
Starp abiem Flo skaidri piedāvā vairāk. Bet Flo funkcijas nāk ar mākoņu apstrādi, abonementiem un dokumentētām privātuma pārkāpumiem. Period Calendar vienkāršība nāk ar reklāmām un mantojuma arhitektūru.
PinkyBloom piedāvā Flo līmeņa iespējas — AI asistents, noskaņu prognozes, veselības krātuve, ārsta ziņojumi — ar Period Calendar līmeņa vienkāršību — nav nepieciešams konts, darbojas nekavējoties. Balss pieraksts nozīmē bezrokas izsekošanu bez manuālām izvēlnēm.
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.
