In some cases, your phone’s operating system may stop our app from running, e.g. due to extreme battery saving or low battery. To prevent this, we recommend adjusting your phone's battery settings. This will ensure the app runs smoothly in the background without interruption, while still consuming very little battery power. To do this, open 'Battery optimisation' in the app settings and the relevant instructions will open. Alternatively, simply open the app once a day.
