Car Heater Timer

Some car heating systems have a timer that needs a bit of math to get correct setting. This little app makes the calculation easy. You just set desired time for departure and heating time (30m to 2h) and the app tells you the setting for the timer.

The app calculates the setting with some safety tolerance. Heating should continue at least 10 min after the desired time of departure. In short heating periods heating also starts a bit earlier. This is because of inaccuracy of this type of mechanical timers.

In dark conditions phone's flashlight will be turned on to assist you. This feature is available in Android 6.0 and above. It also requires you to allow usage of your phone's camera.

The software is in development and in beta phase. It may have bugs and may crash.
