The AI Coach says I need to sign in. AI features have a daily limit, and the limit is per account — so it needs to know who you are. Everything else in the app works without an account.
The AI can't reach the server. Some mobile networks block the addresses our server uses. Try Wi-Fi. If it works on Wi-Fi but not mobile data, email me and say which network you're on.
I lost my data / got a new phone. If you were signed in, sign in on the new phone and use Settings › Account & sync › Restore from backup. Backups happen automatically when you leave the app.
How do I cancel a subscription? Subscriptions are billed by Apple, so cancel in your device's Settings › your name › Subscriptions. Refunds are handled by Apple, not by us.
How do I delete my account? Settings › Account & sync › Delete account. That permanently removes your cloud backup and your sign-in.
The more of this you can include, the faster it gets fixed:
One4 is an independent app. There's no support team — just me — so please be patient, and thank you for trying it.
