What to look for in a Flo alternative
Decide what made you look: privacy, cost, ads, or complexity. Then weigh four things — how your data is handled, the real price after trials, whether your partner can be included, and how much friction there is to start (a separate install and account, or not).
Why people switch to Luna
Luna removes the install entirely — it runs in Telegram. It adds a partner mode most apps lack, keeps core tracking free with an 89-day Pro trial, and speaks 17 languages. For privacy-conscious users aware of Flo's 2021 FTC settlement, an app that isn't in the ad business is reassuring.
Other alternatives worth knowing
Clue is excellent for science-led content; classic free period trackers are fine for basic logging (often with ads). Choose by your top priority — Luna optimises for convenience, partnership and price.
When staying with Flo makes sense
If you mainly value Flo's large content library and community and you're happy in a standalone app, there may be no need to switch. The best alternative is the one that fixes whatever made you look elsewhere.
