Track your period, know your cycle, and never be caught off guard again. CycleNote predicts your next period, fertile window and ovulation from the days you log — all in a calm, private diary that lives entirely on your phone.
Most period apps drown you in ads, accounts and social feeds. CycleNote keeps it simple and personal: log your flow, symptoms and mood in seconds, watch your cycle come into focus on a clean ring and calendar, and get a gentle heads-up before your next period arrives. No login, no cloud, no noise.
WHAT YOU GET
- A clear "today" view showing your cycle day, current phase and days until your next period
- Predictions for your period, fertile window and ovulation that sharpen as you log more
- A full month calendar marking past periods, predicted days, fertile window and ovulation at a glance
- Fast daily logging for flow, 12 symptoms, mood and basal temperature — plus a note for anything else
- Insights that reveal your average cycle length, period length, regularity and most common symptoms
- A plain-language Learn guide to the four phases so every prediction actually makes sense
PERFECT FOR
- Anyone who wants a private period tracker without ads or an account
- People planning around their fertile window and ovulation
- Those tracking PMS, cramps, mood and symptom patterns across their cycle
- Anyone who just wants a reminder before their period starts
WHY NOT JUST USE THE NOTES APP OR A PAPER CALENDAR?
Because CycleNote does the math for you. It spots the pattern in your logs, predicts what's next, and turns months of scattered notes into cycle length, regularity and symptom trends you can actually read — something a blank page never will.
PRIVACY
Your data stays on your device. CycleNote has no account, no sign-in and no cloud sync — nothing about your body is ever uploaded or sold. What you log is yours alone.
FULL ACCESS
CycleNote requires a subscription or one-time purchase — full access unlocks the whole app. Full access includes: period predictions, fertile window and ovulation predictions, full month calendar, daily logging of flow, symptoms, mood and basal temperature, complete cycle insights and regularity trends, symptom-by-phase patterns, and period reminders. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period; manage or cancel anytime in your App Store account settings.
