Comparison
Flo proti Natural Cycles 2026: Primerjava zasebnosti, funkcij in cen
Our verdict
Flo je najbolj priljubljena aplikacija za sledenje menstruaciji na svetu z dokumentirano zgodovino deljenja podatkov z oglaševalci. Natural Cycles je edina aplikacija za kontracepcijo, ki jo je odobrila FDA, vendar stane do 149,99 USD/leto in zahteva dnevna merjenja temperature. PinkyBloom ponuja pametnejšo umetno inteligenco — brez termometra.

Overview
Flo in Natural Cycles predstavljata nasprotni konec spektra sledenja menstruaciji. Flo je vodilni na trgu — brezplačen za začetek, bogat s vsebino in zasnovan za občasne uporabnike, ki želijo celovito zdravstveno platformo. Natural Cycles je nišna medicinska naprava — odobrena s strani FDA za kontracepcijo, klinično potrjena in zasnovana za uporabnike, ki so pripravljeni investirati v dnevno merjenje temperature in premium naročnino.
Moč Flo je dostopnost: prenesite jo, ustvarite račun in začnite slediti z več kot 70 simptomi, tisočimi članki in funkcijami skupnosti. Moč Natural Cycles je klinična verodostojnost: to je edina aplikacija, ki jo je FDA odobrila kot digitalno kontracepcijo (medicinska naprava razreda II, 510(k) K173464), s preglednimi dokazi, ki podpirajo njeno učinkovitost.
Ključna trgovina med njima je strošek in zavezanost. Flo je v bistvu brezplačen za preizkus (z oglasi in premium nivojem za 49,99 USD/leto). Natural Cycles stane do 149,99 USD/leto in zahteva dnevna merjenja bazalne telesne temperature — bodisi s posebnim termometrom bodisi z Oura Ring. Ena je enostavna; druga je učinkovita za specifičen klinični namen.
Privacy comparison
Flo's data sharing is extensively documented. The FTC alleged in 2021 that Flo shared menstrual data with Google, Facebook, and Flurry Analytics; Flo settled with no fine and no admission. A class action settled in 2025, with Flo paying $8M. A California jury found Meta liable for eavesdropping on Flo users' data. Flo's "Anonymous Mode" still uploads data to servers.
Natural Cycles has a cleaner privacy record with no major enforcement actions. However, as an FDA-regulated medical device, Natural Cycles is required to retain user data for regulatory compliance — meaning you cannot fully exercise a right to deletion. All data including BBT readings, sexual activity logs, LH test results, and fertility status is stored on cloud servers. An account with personal information is mandatory.
Both apps store your reproductive health data in the cloud, both require accounts, and both are subject to legal data access frameworks in their respective jurisdictions. The difference is degree: Flo has proven it will share your data; Natural Cycles hasn't, but the architectural vulnerability remains.
PinkyBloom needs no account, and your cycle log is stored on your phone, not in an account on our servers. It's never sold, and partner sharing is end-to-end encrypted.
Features and intelligence
Flo offers the broadest feature set: 70+ trackable symptoms, articles from 120+ medical experts, community forums, pregnancy mode, and a cloud-based AI chatbot. It's a health content platform as much as a tracker.
Natural Cycles offers a focused, clinically validated feature set built around temperature-based fertility detection. The algorithm analyzes daily BBT readings and optionally LH test results to classify days as green (not fertile) or red (fertile/use protection). It's highly effective for its specific use case but requires rigid daily discipline — temperature measurement at the same time every morning before getting out of bed.
PinkyBloom combines broad tracking with intelligent automation. Voice logging lets you say "cramps and fatigue today" instead of tapping through menus. AI mood forecasts predict emotional patterns days ahead. The doctor visit report generator creates professional summaries for healthcare appointments. No thermometer needed, no daily discipline requirement.
Pricing comparison
Razlika v stroških med Flo in Natural Cycles je pomembna. Premium Flo stane približno 49,99 USD/leto; njen brezplačni nivo ima oglase. Natural Cycles je nedavno zvišal cene na 21,99 USD/mesec ali približno 149,99 USD/leto (kar je več od 14,99 USD/mesec pred junijem 2025), kar jo dela eno najdražjih aplikacij za sledenje ciklom na trgu. Dodajte združljiv termometer (15-30 USD) ali Oura Ring (299 USD+), in skupna naložba v treh letih je znatna: Flo približno 150 USD proti Natural Cycles približno 450 USD+ s strojno opremo.
Vrednostna ponudba je jasna, vendar različna. Flo vam daje platformo za zdravstveno vsebino. Natural Cycles vam daje kontracepcijo, odobreno s strani FDA. Vprašanje je, ali katera koli od njiju upravičuje stroške — in podatke, shranjene v oblaku — ko obstajajo boljše alternative.
PinkyBloom je brezplačen. Brez potrebne strojne opreme. Stroški v treh letih: 0 USD. PinkyBloom ni kontracepcija, odobrena s strani FDA, vendar za večino potreb po sledenju ciklom — napovedi, simptomi, zavedanje o plodnosti, sledenje razpoloženju, zdravstveni zapisi — ponuja več funkcij kot Flo.
There's a better option
Flo has the features but betrayed user trust. Natural Cycles has the clinical credibility but costs $150/yr and requires a thermometer. PinkyBloom delivers a built-in AI assistant, no account, and a price of $0 — no hardware needed.
