About
TideNote is a quiet period tracker.
30-second logging. Gentle reminders before you need them. Your data never leaves your phone.
No accounts, no ads, no nagging.
What you can do
• Mark period days with a tap or drag — the algorithm never overrules you
• Track flow, cramps, mood, and a one-line note in under 30 seconds
• See the next period predicted with honest uncertainty, not false precision
• Get a heads-up 3 days and 1 day before — pads, painkillers, and anything you add to your supply list
• Mark a trip on the calendar — if it overlaps your cycle, TideNote pings 2 days early
• Painkiller spacing: gentle reminders every 4 / 6 / 8 / 12 hours during your period
Private by default
• All entries stay in local storage. No sign-in. No cloud upload. No third-party SDKs.
• Notifications run on-device — your reminders never leave your phone.
• Follows your phone's language and date format automatically.
What we don't do
No social feed. No shop. No "fertility coach". No 50-symptom checklists you won't use. TideNote does two things — record and remind — and
tries to do them well.
A note on health
TideNote is a journaling tool, not medical advice. Cycle predictions are estimates only. For fertility, contraception, or any health concern,
please consult a clinician.
