Phase: Period & Cycle Tracker

Log your period in a tap. Private, ad-free, and fully on-device — with gentle predictions for your next period, fertile window, ovulation, and mood.

Phase is a calm, private period and mood tracker that helps you understand your body — without ads, accounts, or judgment.

Log your period in a single tap and Phase predicts your next period, fertile window, and ovulation day. Track your mood, energy, and symptoms, and see how they shift across your cycle.

PRIVATE BY DESIGN • Your data stays on your device — no account, no sign-up, no tracking. • We can't see your data, and we never sell it.

SIMPLE TO LOG • Mark your period start and end in seconds. • Log mood, flow, and symptoms like cramps, headaches, and tiredness. • Built for real, irregular cycles — log multiple periods and edit any day.

KNOW WHAT'S COMING • Clear predictions for your next period, fertile window, and ovulation. • A beautiful cycle ring shows exactly where you are today. • Gentle reminders before your period — never spammy.

INSIGHTS THAT MATTER • See your average cycle and period length from your own history. • Discover how your mood changes across each cycle phase. • Export your full history as a PDF or CSV anytime.

TRYING TO CONCEIVE — OR JUST TRACKING • Follow the full period → ovulation → pregnancy-chance window. • Honest predictions that adapt to your real data, including irregular cycles.

Phase is free to use. An optional premium unlock supports the app and adds deeper insights — there's no paywall on the basics.

Phase is not a medical device and does not provide medical advice or contraception guidance. Always consult a qualified healthcare professional with any questions about your health.
