Overview
Flo in Period Calendar podjetja Simple Design sta po številu prenosov dva najbolj priljubljena sledilca menstruacij, kar jih je bilo kdaj ustvarjenih. Flo trdi, da ima 440 milijonov uporabnikov; Period Calendar trdi, da ima 300 milijonov. Skupaj predstavljata skoraj tri četrtine milijarde računov, ki sledijo podatkom o reproduktivnem zdravju.
Aplikaciji sta si drastično različni v pristopu. Flo je celovita zdravstvena platforma z AI chatbotom, forumom skupnosti, strokovnimi vsebinami in premium naročninami. Period Calendar je preprost, brez frills sledilec — zabeležite svojo menstruacijo, si oglejte napovedi, sledite simptomom. Flo cilja na angažiranega potrošnika zdravja; Period Calendar cilja na uporabnika, ki želi preprostost nad vsem.
Kar ju povezuje, je vrzel v zasebnosti. Flojeva je dokumentirana na zveznem sodišču. Period Calendarjeva je vgrajena v njen poslovni model — trdi, da ne zbira podatkov, medtem ko izvaja Google oglasne SDK-je, ki po zasnovi zbirajo podatke.
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 je bogata s funkcijami: 70+ simptomov, AI chatbot, forum skupnosti, način nosečnosti, vsebine od 120+ medicinskih strokovnjakov. To je zdravstvena platforma, ne le sledilec.
Period Calendar je preprosta funkcionalnost: beleženje menstruacije, ocene ovulacije, sledenje simptomom in koledarski pogled. Plačana različica odstrani oglase. To je orodje za beleženje, ki zanesljivo opravi osnove.
Med obema Flo jasno ponuja več. Toda Flojeve funkcije prinašajo oblačno obdelavo, naročnine in dokumentirane kršitve zasebnosti. Preprostost Period Calendar prinaša oglase in zastarelo arhitekturo.
PinkyBloom ponuja zmogljivosti na ravni Flo — AI asistent, napovedi razpoloženja, zdravstveni trezor, zdravniška poročila — s preprostostjo na ravni Period Calendar — brez potrebe po računu, deluje takoj. Beleženje z glasom pomeni sledenje brez rok brez ročnih menijev.
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.
