History is stored on your device only. ON YOUR WRIST A dedicated Apple Watch app shows inside temperature and hot water side by side, with battery and energy source, and lets you adjust the room temperature, heating mode and hot water with large buttons that show the active setting. Get an alert right on your wrist the moment something needs attention. IN THE CAR Check your camper's status from the CarPlay screen: large colored cards for inside temperature, hot water, battery and energy, plus connection details, laid out for a quick glance with minimal distraction. ON YOUR HOME SCREEN AND LOCK SCREEN Add the Tru-Control widget to see your heater's last known status without opening the app, or start the Live Activity to keep temperatures, battery and energy source on your Lock Screen and Dynamic Island while the app is connected. ON IPAD Tru-Control runs as a compact floating window you can place next to other apps. ONE-TIME PURCHASE A single one-time purchase unlocks commands, Apple Watch, CarPlay and the widget.
