Tide: Period & Cycle Tracker

Tide is a period and cycle tracker that flows with your body, not against it.

Built around the rhythms of the ocean — tides, seasons, and natural cycles — Tide gives you a calm, beautiful space to log your period, understand your body, and notice the patterns that matter.

MADE FOR EVERY BODY Whether you're tracking your period for the first time, navigating an irregular cycle, or moving through perimenopause — Tide adapts to where you are. We use inclusive language throughout, so the app feels like it's actually for you.

WHAT YOU CAN TRACK

• Periods and bleeding — log start and end days, flow level, and symptoms. Add past periods retroactively without breaking your history.
• Daily check-ins — how you're feeling each day, including mood, energy, and sleep.
• Pad and product changes — log changes with optional reminders so nothing slips your mind.
• Cycle phase visualization — your phases mapped to seasons and tidal states, so you can see at a glance where you are.
• Body Connections — gentle, time-aware insights about how your body shifts across your cycle.

A GENTLER TONE Tide has reminders, notifications, and encouragement — but the language is designed to feel like a gentle nudge from a friend, not a guilt trip from an app. Plain, honest, and never alarmist, especially around the moments that matter most.

PRIVATE BY DEFAULT

• No ads. Ever. Tide does not run ads and never will.
• No data sold or shared with advertisers.
• You own your data. Delete your account anytime — and when you do, your data is permanently and immediately removed, with no waiting period.
• Analytics and crash reporting are used only to keep the app working and improve it.

COMPLETELY FREE Tide v1.0 is fully free. No subscriptions, no paywalls, no locked features.

IMPORTANT Tide is a tracking and reflection tool. It does not diagnose conditions, predict fertility for contraception, or replace medical care. If you have concerns about your cycle, please speak with a qualified healthcare provider.
