1. What the app does

One Second Run helps you complete a simple running or walking timer. Each completed day unlocks tomorrow's goal by one second.

2. Resetting progress

You can reset progress and choose a new start time from Settings. These actions may require watching a rewarded ad. A rewarded ad may also appear after completing today's run.

Resetting deletes run history and current progress, but keeps app settings. To delete all locally stored app data, remove the app from your device. There is no account or server backup to restore.
