Garāža keeps track of what your car needs and when. You tell it the service intervals once, log the odometer now and then, and it works out what is coming up next.
It also knows which wheels should be on the car this time of year. The Latvian tyre-season rules are built in, along with seasonal storage for the set you are not using. It works for one car or a whole family's, and the next due item sits on your Home Screen or Lock Screen as a widget.
