HELP
Q: Why the timer doesn't work in the background?
A: You should allow notifications.
Q: How to turn off the sound and turn on the vibration?
A: On the device, turn the Silent Mode on. (Side Switch)
Q: Alert is limited for 5 seconds!
A: Go to Settings app, then Periodic Timer > Notifications > Banner Style > Persistent.
Q: How to switch the Timer Output Mode?
A: To switch the Output Mode touch the timer display at the top of the screen.
Q: What is Shake To Start for?
A: Shake To Start setting allows to start/cancel the timer by shaking the device. Thus, you don't touch the screen, what can be useful while cooking, for example. In order for this mode to work, the app should be open.
