About

What's New in My Best Days

1.3

October 30, 2026

What's new in My Best Days 1.3 • Share your cycle with your partner. Show a code in Settings → Partner sharing and your partner scans it with their own app. They see your cycle day, next period, fertile window and calendar, and nothing else. It's end-to-end encrypted, and you can stop sharing any time. • Partner mode. Here to follow your partner's cycle? Choose "I'm here to see my partner's cycle" when you set up and go straight to their cycle. • A real Apple Watch app. Swipe between Today (your cycle ring, phase, next period and fertile window) and Log (period, mood and symptoms in one tap). New watch-face complications too. • Log from your wrist. Reminders now have buttons such as Started / Not yet and Good / Okay / Rough, and you can dictate a quick note. • Quick check-ins before your period. In the 5 days before your period, answer two quick questions a day with one tap. • Founding members get Premium free. Create a free account during our launch to unlock the fertile window, charts, pregnancy mode, patterns and export. • More private and secure: – Your backup is end-to-end encrypted. We can't read it, and your next phone restores it automatically. – The data on your phone is encrypted too. – With app lock on, the app switcher hides your data and reminders say only "You have a reminder." – No ads and no tracking. • A new animated opening screen, and Face ID opens by itself again when you come back to the app. • Now in English, Spanish, French and Sinhala, including reminders and emails. • Sign up with Google now works on iPhone. • Needs iOS 15 or later.
