Looking for a Flo alternative? Read this first

Let’s start with fairness: Flo is the biggest period tracker on earth for real reasons. It’s polished, its content library is enormous, and hundreds of millions of people have found it genuinely useful. If you’re reading this, though, something sent you looking — and for most people it’s one of four things.

Why people go looking

The account. Big trackers want a sign-up before your first log, which ties your reproductive history to an identity on their servers. The cloud. Your data living in someone else’s database means trusting their security, their privacy policy, and every future owner of the company — Flo settled with the FTC in 2021 over sharing health-event data with third-party analytics firms, and while its practices have since improved (including an anonymous mode), the structural question remains for every cloud tracker. The noise. Some people just want a tracker, not a social feed and a daily push campaign. The price. Premium tiers around $50–60/year add up when the free tier keeps shrinking.

What actually matters in a replacement

• Where the data lives. On-device with encryption beats “we promise to be careful with our copy.” An app-store privacy label reading “data collected: none” is the checkable receipt.
• No account required. If it can’t work without your email, the email is part of the product.
• Honest predictions. Ranges and visible confidence — especially if your cycles vary. A single confident date is marketing, not math.
• A real business model. Somebody pays for every app. If it isn’t you, look harder at what is being sold.
• An exit. Real deletion and full data export. Your history should be portable the day you want to leave.

The honest landscape

You have real choices, and they cluster into three camps. Big cloud trackers (Flo, Clue, and friends): the most features and content, with the structural cloud trade-off — Clue deserves credit for European privacy law and clear policies, but your data still lives on servers. Open-source local apps (like Drip or Euki): genuinely private and free, with volunteer-project interfaces and few insights — excellent if minimalism is the goal. Private-by-design commercial apps — the newest camp, trying to pair on-device privacy with a polished, full-featured experience. That’s where Evette lives.

Where Evette fits — and where it doesn’t

Evette’s bet is that you shouldn’t have to choose between a beautiful, intelligent tracker and your privacy: no account, health log encrypted on your phone, predictions that show their work with honest ± ranges, cycle and BBT charts, fertility and pregnancy modes, and a clinician-ready PDF export — with tracking free forever and one subscription (Bloom) for the deep insights.

And where it doesn’t fit, honestly: Evette won’t sync across five devices (nothing to sync from — that’s the point), doesn’t have a community feed, and its content library is months old, not a decade deep. If those matter most to you, a cloud tracker is the right call, and Clue is the one we’d point you to.
