What to include in a bug report

  • Your iPhone or iPad model and iOS/iPadOS version.
  • The App version shown under Progress > Settings & privacy > About.
  • What you expected, what happened, and the steps to reproduce it.
  • A screenshot if it does not contain private information.

Never email a password, Sign in with Apple authorization code, refresh token, or other secret.

Progress and Sign in with Apple

The App works without an account. If you later sign in, guest progress is merged into your Apple-linked mobile account. If progress does not appear, confirm you are using the same Apple account, reconnect to the internet, reopen the App, and then contact us if the issue continues.

Delete your account

Open Progress > Account > Delete account and cloud data, review the warning, and confirm. The App requests deletion from the mobile service and clears local progress after server confirmation. If you cannot access the App, email hi@1600.lol from the address associated with Sign in with Apple.

Guests can use Progress > Account > Delete guest progress and cloud data to remove local progress and guest cloud records tied to that app installation.

Payments

The first release is free. It has no subscription, in-app purchase, advertising, or billing flow, so the App will not charge you.
