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 โ€ข PCOS โ€” irregular cycles, fatigue, mood and sleep, logged alongside your own triggers so you can see which ones come up most. โ€ข Postpartum โ€” night sweats, sleep, mood and the return of your cycle, in the months when nobody is measuring anything. โ€ข Perimenopause & menopause โ€” hot flashes, night sweats, brain fog, joint pain, plus HRT reminders with application-site rotation. โ€ข Not sure yet โ€” that is a valid answer. Start logging; the pattern names itself. WHY EBB โ€ข 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 a range based on the cycles you log and explains why it's a range. โ€ข HRT reminders that fit how you take it. Set a schedule for a patch, gel, oral tablet, cream, injection, pessary or hormonal coil, get a reminder when the next dose is due, and follow a suggested application-site rotation. Tap Taken and the dose is added to your history. โ€ข See your own pattern. After three days of logging, Trends shows your most frequent symptom and how the last 7 days have been trending โ€” free. Ebb Pro adds your full history, your HRT doses listed next to your symptom trend, and a count of the triggers you log most often (caffeine, alcohol, stress, poor sleep). โ€ข A doctor visit report (Pro). Generate a PDF summary of your average symptom scores, logged HRT doses and notes โ€” built for the appointment that's never long enough. โ€ข Home & Lock Screen widgets and an Apple Watch complication for your next dose โ€” free. โ€ข No account, no ads. Your log is stored on your device โ€” Ebb keeps no copy on a server. 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. Free: daily logging, your cycle range, one HRT schedule with reminders, widgets and your first pattern in Trends. Ebb Pro is an auto-renewing subscription (weekly or annual) that adds your full history, your HRT dose list alongside your symptom trend, the trigger breakdown, the doctor visit PDF and unlimited HRT schedules. Where a free trial is offered, the length and the price that follows are shown on the purchase screen before you confirm. Payment will be charged to your Apple ID account at confirmation of purchase. Subscriptions automatically renew unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your Account Settings.
