Ratings & Reviews

  • This app has not received enough ratings or reviews to display an overview.

New home screen: while the heater runs, an orange card with a progress ring shows the time left. Otherwise the next run is front and centre – with weather forecast, week strip and whether the heater confirmed the timer. A paused weekly schedule can be resumed right from the home screen. Also: choose Light, Dark or System appearance, animated launch screen, longer times in days and hours, the new overview on Mac and more reliable iCloud sync of the weekly schedule.
