Sometimes I forget to turn on the sleep tracker. Then the app thinks I hardly slept. Is there av way to edit this?
Sure, you can add a manual sleep record to account for the untracked time:
Go to graphs screen and add a new record using the plus button.
You can also edit the graph:
Please go to the graph detail screen, there you can use your finger to select any portion of the recording and tap the trash can icon at the top to get rid of the redundant part.
