The 'Shake To Start' feature allows you to initiate or cancel the timer by shaking your device. This is particularly useful when your hands are occupied, such as during cooking. For this feature to work, the app must be open.
To ensure alerts are persistent, navigate to your device's Settings app, then find Periodic Timer > Notifications > Banner Style, and select 'Persistent'. This will prevent alerts from disappearing too quickly.
