iPhone
A period diary that stays on your phone. Log in one tap, get a date, keep your data.
Fase is a period diary, not a health platform.
Log a period day in one tap, from the app or the widget. Fase predicts your next period from your own cycles, shows the expected days on the calendar and reminds you before it comes. Symptoms, pain and mood live in a simple daily sheet.
WHAT STAYS FREE, FOREVER
• Calendar, logging, predictions, reminders, widget
• Import your history from Apple Health in one tap
• A one-page report to bring to your doctor
• Backup and restore of your diary as a file
NO ACCOUNT, NO ADS
There is nothing to sign up for. Your diary is a single file on your phone. Nothing you log is uploaded anywhere.
FASE PRO (optional subscription)
When you have logged two cycles, Fase Pro reads your diary back to you: how regular your cycle is in days, when each symptom usually shows up, your premenstrual window drawn on the calendar, twelve months of expected dates, and the doctor's report with the patterns included.
Fase is a diary. It is not a contraceptive and not a medical device: it must not be used to plan or avoid a pregnancy. Predictions are averages of the cycles you log.
Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period, in your Apple ID settings.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Couple agenda: appointments, scans and tests in your Calendar, with reminders. Invite your partner with a link: they see your appointments in Fase on their iPhone, never your diary. Free.
• With Fase Pro your partner also sees your cycle day (in pregnancy the week, after the birth the time since) and you can invite a second person.
• Fase Pro follows your life stage: cycling, pregnant, after the birth or after 40, you get what matters there. In pregnancy there is also a 6-month plan; the first week is free on the yearly and 6-month plans.
• After the birth, bleeding doesn't count as a period: you say when your period is back, and the average starts again from there.
• Calendar: during your period you also see the days likely still to come, marked as expected with a dashed border.
• The PDF report runs onto more pages when it needs to: no more cut-off lines.
Your diary stays on your iPhone, with no account. The agenda goes through your iCloud, encrypted.
