Ebb

Hormones don't run on a schedule โ so why do period apps pretend they do? Ebb is a symptom and cycle tracker for the hormonal stages other apps skip: PCOS, postpartum recovery, perimenopause and menopause. Log how today felt, mark the days that matter, track HRT or other doses, and see an honest RANGE for your cycle instead of a fake-precise date that falls apart the moment your body doesn't cooperate. Irregularity is normal here. It's not a bug in your body, and it's not a bug in the app. WHO EBB IS FOR โข PCOS โ irregular cycles, fatigue, mood and sleep, tracked against your own triggers so you can see what actually moves them. โข Postpartum โ night sweats, sleep, mood and the return of your cycle, in the months when nobody is measuring anything. โข Perimenopause & menopause โ hot flashes, night sweats, brain fog, joint pain, plus HRT doses with site rotation and phased schedules. โข Not sure yet โ that is a valid answer. Start logging; the pattern names itself. WHY EBB โข Honest ranges, not false predictions. Other apps silently push your "due date" forward when you don't log a period, or just give up and hide the prediction entirely. Ebb shows you your real recent range and explains what's actually going on. โข HRT and hormone dose tracking done properly. Log patches, gels, oral tablets, creams, injections, or a hormonal coil โ with dose amounts, application-site rotation reminders, and cyclical/phased schedules for progesterone. โข See what's actually correlated. Compare your symptom trend against your dose changes and your own logged triggers (caffeine, alcohol, stress, poor sleep) โ not a guess, your own data. โข A doctor visit report in one tap. Generate a clean PDF summary of your symptoms, doses, and notes โ built for the appointment that's never long enough. โข Home & Lock Screen widgets, and an Apple Watch complication for your next dose. โข No account, no ads. Your log stays on your device and in your iCloud. Nearly 40% of women say they were misdiagnosed while seeking care for perimenopause โ often treated for anxiety or depression instead of investigated for the hormonal cause. For a third of women with PCOS, a diagnosis takes more than two years and three or more doctors. Bring real data to your next appointment.
