This release makes signing in simpler: no password, and you stay signed in for a year.
- Sign in with your email. Tap Continue with email and Onsen emails you a button and a code. Tap the button on your phone, or type the code. No password needed.
- One way in. Continue with email works whether you are new or coming back, so there is no more choosing between Sign up and Log in. Apple and Google sign-in are still there, and the one you used last is marked.
- Stay signed in for a year. You used to be signed out after 30 days. Your sign-in details are now kept in your phone's secure keychain.
- Still have a password? Choose Use password instead. If you forget it, Onsen emails you a code.
- A shorter sign-up. A new account needs only your first name and two ticks. Your birthday is optional and asked later.
- A birthday look-back. Add your birthday in Settings and Onsen sends you a look back at your year on the day. Birthday and anniversary messages now arrive on the right day in your own time zone.
- Help when the email doesn't arrive, and new illustrations across sign-in.
- Deleting your account now asks one optional question about why, so we can make Onsen better.
- Fixed a crash that could close the app when it reloaded.
Thanks for being part of the journey.
