About this app

See (and graph!) exact temperatures throughout your food while it cooks. Know exactly when it will be done. View and graph core, surface, and ambient temps in real time.

The wireless Predictive Thermometer was built to answer a simple but important question: when will my food be ready? Combustion’s Predictive Engine™ estimates exactly when that will be, using the data from 8 onboard sensors (the most of any cooking thermometer).

Important firmware updates! The Combustion App includes the latest firmware updates for Predictive Thermometers and other Combustion Accessories including Boosters, Displays, Giant Grill Gauges and other forthcoming products. Firmware updates improve core functions including time-to-cook predictions, longer battery life, and can add new features.

MeatNet™ Cloud – for functionally unlimited range! Use with WiFi Accessories or with a second mobile device to stream your cook data to the cloud. Watch your cook in real-time from anywhere with internet access.

Get more consistent results with all your favorite foods: steak, pork chops, brisket, pork shoulder, roasts, turkey, whole chicken, ribs, fish, bread, and more.

Advanced graphing on the Combustion App helps you visualize exactly how heat moves through your food. You will understand the relationship between ambient cook temps and surface temps. And how surface temps really control how long things take – and how evenly food cooks. It may shock you to find out the oven temp (or grill temp) you set is not the same as the food is actually experiencing!

The Combustion Inc app puts all that knowledge in front of you – with instant feedback, so you’re not just cooking better, you’re also learning as you go.

And learning has never been so delicious.

Ratings and reviews

The update from Dec 2024 created some problems with setting the desired temp for predicting. They made a new update in Jan that fixed a thermometer connectivity problem with app and now things are pretty great again. I still see the app fail when trying to set the prediction temps, but it's better.

Firstly - my thermometer was DOA. Never charged, never could stay connected. Secondly, the app is confusing AF if you need help or want to do some troubleshooting, as it gives you no control or insight as to what is going on the system, and your intuition will not help you try to figure it out. Very expensive metal stick to buy.

Fantastic thermometer and a very easy to use app. You still need to make sure you know how to properly insert the probe but with all the sensors it's not nearly as critical to hit the one "sweet spot" that you had to with old steam gauge ones. I took one star away because mine does not measure ambient temperature correctly but with an oven thermometer it's no big deal- merely surprising. Cannot recommend strongly enough.

What’s new

More stable and accurate predictions! Improved power management with optional “always on” mode (aka sous vide mode). Added “reset” function – easily start a new cooking session or reboot your graph.

Includes vital firmware updates for WiFi Booster, WiFi Display, and 1st and 2nd Gen Predictive Thermometers. Better, more stable WiFi connections + improved compatibility with more routers and configs.

Includes “rescue mode” which auto-repairs partial or failed firmware updates. Just in case!
