Our verdict
Flo er den mest populære menstruationsapp med over 440 millioner brugere, men betalte $8M i en gruppering for at dele data med Google og Meta. Clue er videnskabsbaseret med stærk GDPR-overholdelse, men opbevarer stadig data i skyen og koster $39.99/år.

Overview
Flo and Clue are the two most commonly compared period tracking apps in the world. Flo leads in raw popularity with over 440 million users and a massive content library. Clue, based in Berlin, has built its reputation on scientific rigor, a clean interface, and GDPR compliance. Both apps serve the same core need — cycle tracking — but they approach it differently.
Flo emphasizes breadth: 70+ symptoms, AI-powered health chatbot, community forums, pregnancy content, and articles from 120+ medical experts. Clue emphasizes depth: research partnerships, medical device certification (CE-marked Class 1), and data-driven predictions without the marketing noise. If you want a health content platform, Flo is the obvious choice. If you want clinical accuracy with less clutter, Clue wins.
But both share a fundamental limitation: your data lives on their servers. Flo's data is stored on US infrastructure; Clue's on EU servers. Both require email accounts that tie your identity to your reproductive health data.
Privacy comparison
This is where the Flo vs Clue comparison gets serious. Flo has the worst documented privacy record in the period tracking industry. In 2021, the FTC alleged Flo shared menstrual data with Google, Facebook, and Flurry Analytics despite promising users their data was private; Flo settled, with no fine and no admission. In September 2025 a class action settled — Google paid $48M, Flo $8M. Then in August 2025, a California jury found Meta liable for "intentionally eavesdropping" on Flo users' menstrual data under California wiretap law. Flo's "Anonymous Mode" still uploads data to servers; it just strips your name.
Clue is meaningfully better. BioWink GmbH operates under GDPR in Berlin, stores data on EU servers, and has publicly committed to never selling user data. No major breaches or enforcement actions. Clue is the privacy-conscious choice between these two.
But "better than Flo" is a low bar. Clue still stores your data in the cloud. An email account is required, linking your health data to your identity. GDPR provides strong protections but doesn't prevent lawful government data requests within the EU. Cloud storage is inherently vulnerable to breaches, insider threats, and policy changes.
PinkyBloom needs no account and no email. Your cycle log is stored on your phone, not in an account on our servers. It's never sold, there are no ads, and partner sharing is end-to-end encrypted.
Features and intelligence
Flos funktionssæt er bredere. Over 70 sporbare symptomer, tusindvis af artikler fra medicinske eksperter, et fællesskabsforum, graviditetsmode og en cloud-baseret AI-chatbot. Det er designet til at være en omfattende sundhedsplatform for kvinder, ikke kun en menstruationsapp. Ulempen: premiumfunktioner kræver et abonnement, den gratis version har annoncer, og AI-chatbotten behandler dine data på fjerntliggende servere.
Clues funktionssæt er mere fokuseret. Stærke cyklusforudsigelser støttet af forskningspartnerskaber, brugerdefinerede tags til at spore alt, og en ren Analyse-fane til mønstergenkendelse. Clue Plus ($39.99/år) låser op for avancerede forudsigelser og Conceive-mode. Interfacet er minimalt og videnskabsfremadskuende. Ulempen: ingen AI-assistent, begrænset uddannelsesindhold sammenlignet med Flo, og færre livsfasefunktioner.
PinkyBloom kombinerer det bedste fra begge tilgange og tilføjer funktioner, som ingen af dem tilbyder. Voice logging erstatter manuel symptomregistrering. AI-stemningsprognoser forudsiger følelsesmæssige mønstre dage i forvejen. Rapportgeneratoren til lægebesøg skaber professionelle sundhedssammendrag. Krypteret partnerdeling gennem PinkyBond, widgets til startskærmen i tre størrelser, og en Face ID-beskyttet sundhedsboks afrunder et funktionssæt, der overstiger både Flos bredde og Clues dybde.
Pricing comparison
Flos prissætning er kompleks og nogle gange uklar. Det premium abonnement koster cirka $49.99/år, selvom Flo er kendt for at A/B teste priser efter region og brugersegment. Den gratis version inkluderer annoncer og begrænser adgangen til nogle funktioner. Over fem år koster Flo cirka $250.
Clue Plus koster $39.99/år. Den gratis version er funktionel, men låser avancerede forudsigelser, Analyse-fanen og Conceive-mode bag betalingsmuren. Over fem år koster Clue cirka $200. Du får en ren, annoncefri, GDPR-kompatibel oplevelse — men du betaler stadig for cloud-lagrede data.
PinkyBloom er gratis. Ingen annoncer. Sammenligning af omkostninger over fem år: Flo ~$250, Clue ~$200, PinkyBloom $0.
There's a better option
Both Flo and Clue store your data in the cloud and charge for premium features. PinkyBloom stores your cycle log on your phone and needs no account. You get more AI than Flo.
