GrillThermo vs Tru

An APP that can monitor the barbecue temperature in real time can see the barbecue time and temperature on the phone, and remind you when the temperature is no longer within the range of barbecue, or remind you at the set time.

Complete camper and RV heating management, reimagined for iOS — now with Apple Watch, CarPlay, a Home Screen widget and Live Activity.

Get an alert right on your wrist the moment something needs attention. IN THE CAR Check your camper's status from the CarPlay screen while you drive: connection status, temperature, battery, and heating mode, 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 a Live Activity from Settings to keep the status on your Lock Screen and in the Dynamic Island while the app is running.

Purchases can be restored at any time from Settings, and offer codes can be redeemed in the app. Tru-Control is an independent, unofficial application and is not affiliated with, endorsed by, or sponsored by any heating system manufacturer.
