Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Version 2.1 is our biggest update yet.
- Your journal is now free: unlimited entries with a photo, mood, place and weather, the Face ID lock, calendar, timeline, widgets, backups and the Apple Watch app. Premium is optional and adds Decoy Mode, iCloud sync, voice notes, dreams, time capsules, insights, themes and more.
- A new look, Paper & Midnight: warm paper by day and midnight ink at night, redesigned across every screen.
- Password-protected backups: AES-256 encrypted, including photos and voice notes, and restorable on any device.
- A real Apple Watch app: log a mood in one tap or dictate a quick note, and it's added to that day's entry on your iPhone.
- Better Decoy Mode: calculator, notes and weather disguises that behave like the real thing and come back whenever you leave the app.
- New widgets for the Home Screen, Lock Screen and StandBy that show your streak and moods, never your words, and show nothing about your journal while Decoy Mode is on.
- iCloud sync rebuilt from the ground up, and now off until you turn it on.
- Lighter photos saved without location data, daily reminders that never reveal what you wrote, and many fixes.
