A range, not a promise: "Oct 27 to 30", with the reasoning one tap away. It gets sharper as you log more.
Fertile window and ovulation shown in FlowTrax are estimates for education, based on what you log. They are not a contraceptive and not a medical diagnosis.

Real app screens · mock data
Log flow, symptoms, discharge, feelings and more from one sheet, right on the Today screen. Add as much or as little as you want.
Names, dates and numbers in the screens are mock data. FlowTrax is in development, so details may change before launch.
No more "what's wrong?" "nothing." You choose who to share with and exactly what they can see, from period dates to how you feel. They get a calm, view-only screen, and you can stop sharing any time.


Sharing is optional and view-only by default. You pick who, what and for how long, and personal notes are never included.
Your cycle touches your sleep, your mood, your plans and a surprising number of conversations. A friendly record does more than you'd think.
After a few cycles you can see your own cycle and period length in plain words, not a stranger's average.
Hand over a tidy history of what you logged, instead of guessing "was it three weeks ago?"
A next-period range, clearly marked as an estimate, so you can plan around it instead of panicking about it.
Share a mood, not a monologue, with the one person you choose.
Private notes, a lock screen that says nothing, and you can export or delete everything.
No streaks, no "you missed a day". A skipped day is just a skipped day.
It shows an estimated ovulation day and fertile window based on what you log, drawn with its own symbol and always labelled as an estimate. It is educational, not a contraceptive and not a medical diagnosis.
Yes. With fewer logged cycles it shows wider ranges and tells you it is still learning, instead of faking a confident date. A late period is described neutrally, never as a guess about why.
No. Skip questions, come back later, and edit old entries. FlowTrax has no streaks to keep and no guilt for skipped days.
Your cycle data is yours. Reminders are discreet by default, partner sharing is optional and you choose exactly what is shared, and you can export or delete your data. Read how we handle waitlist emails in the privacy notice.
