A window, not a date
Your next period is shown as a range with a confidence, because that is what the data supports. The softer the edges, the less sure we are — and you can see it.

Every stage
Most apps cover one chapter. This one follows the whole book.
When your life changes, femio re-arranges around it — it never starts you over and it never deletes what came before.
- First periodsGuides in plain language; no tracking mode yet
- Cycles & conditionsPCOS, endometriosis, heavy or absent periods
- Trying to conceiveFertile window, and when to ask for help
- PregnancyWeek by week, with warning signs kept in front
- After birthRecovery and mood guides; no tracking mode yet
- Perimenopause & menopauseSymptoms tracked, without a countdown
Your record is one record. Switching stage re-layers what you see over it — nothing is archived away from you, and you can switch back.
Honest by design
We would rather be useful than certain.
No “you are 4 days late”
Cycles shift for dozens of ordinary reasons. If the window passes, femio says so and stops — it does not run a counter at you.
Your window has passed. Cycles shift — this is common and usually not a problem.
Your own pattern, not an average
Everything is compared against your history — including when your cycles are irregular, which is exactly where other apps give up.
Private by design
Your records stay on your phone.
The femio app keeps what you log on your device. We never see it, so there is nothing for anyone to sell, share or lose.
- No account neededOpen the app and start. No email, no password.
- femio never sees your entriesYour periods, symptoms and pregnancy stay on your phone.
- Back up when you chooseSave a backup file wherever you like, and restore it on a new phone.
Why trust it
Four things you can verify.
- Every claim is cited, and dated — NICE, ACOG, WHO, ESHRE, linked, with the date the page was last reviewed.
- Every guide says whether a clinician reviewed it — a named clinician with credentials on the pages they reviewed, and “clinician review pending” on the rest.
- No health data reaches an advertiser — ever. It is not a setting; there is no channel.
- English, Arabic, French and Spanish — Arabic right-to-left from the first line of code, not a layer added later.
