You can set reminders in the workrest app to log your rest hours to ensure you don't forget.
To set reminders, when you're next logged into the workrest app:
Select Menu ☰ (bottom right)
Then Settings
Select ‘Reminders’ from the menu
Select the days you wish to be reminded on
Tap the ‘Time of reminder' area and select the time for the reminder
If you've not given workrest permission to send you notifications, you'll be prompted to give workrest permission once you've created your reminder.
To edit your reminders, simply follow the steps above again.
To cancel your reminders, press on the highlighted day's' in which the reminder occurs, which will remove the reminder for that day.
