Phase: Period & Cycle Tracker

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.
