About this app

See (and graph!) exact temperatures throughout your food while it cooks. Know exactly when it will be done. When used with the Combustion Display or Booster, the app extends the signal strength (max range) of the Predictive Thermometer an additional 330ft (100m). View and graph core, surface, and ambient temps in real time.

Works with all kinds of foods and most cooking appliances - BBQ smokers, ovens, ranges, grills, and more - indoors and out.

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).

This app allows you to set your target doneness and shows the prediction, along with the three most important temperature readings: core (internal temp), surface temp (true cooking temp), and ambient temp (the air around your food).

Use this app to update firmware on your wireless Predictive Thermometer, Display, and Booster. Firmware updates improve core functions including predictions, extending battery life, and add new hardware functions.

Graph your food’s temperatures in real-time! See exactly how heat moves through your food. Understand how surface temps translate to core (internal) temps and see how the oven temp you set is not the same as the food is actually experiencing (it may shock you!). The Combustion Inc app puts all that knowledge in your hands, for better results every time you cook.

Better cooking, better eating – that’s what it’s all about.


–Wander farther: extends signal range of the Combustion Display – watch your food from across the house or across the park, without having to hover (especially useful when you’re cooking inside something radio-resistant like a heavy metal BBQ grill or smoker)
–Use with or without the Combustion Display
–Works with Combustion Booster to extend range
–Enables multi-node MeatNet: use a combination of Booster(s) and Display(s) to greatly extend signal range + strength
–Set target temp: so that your food comes out just the way you want it
–See key temps in real-time: including core, surface, ambient
–See predictions in relative time (“ready in” countdown) or in absolute “clock” time
–Get notifications for important cooking events with advanced alerts (ready alarm, 5-minute warning, disconnect alert, low battery notification)
–Graph key temps as they happen
–Export cooking data from start to finish, so you can fine-tune your technique
–See (and graph) temperatures from all 8 sensors with Advanced Cooking Mode
–Update firmware: get better performance and new features for the Predictive Thermometer, Display and Booster
–Works with most cooking appliances and cookware types
–Works with all kinds of food
–Bluetooth connectivity - does not rely on internet or WiFi
–No accounts or sign-ins required

You can cook using just the app and a Predictive Thermometer. But if you also have a Combustion Display or Booster, the app uses that as a signal repeater. Keep an eye on cooking temps from across the house or across the park. That signal boost comes in especially handy when the thermometer is inside something radio-resistant, like a heavy metal grill or smoker.

The Predictive Thermometer has an array of 8 sensors and compares temperatures to always locate the lowest internal temp. We call that TrueCore and it means you never measure the wrong spot! Even when the food you’re cooking is small (like a filet) or irregular (like a whole chicken), your food won’t ever end up undercooked or raw in the middle.

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

The thermometer itself is great but the app leaves something to be desired. every time I enter a prediction it will tell me that it failed to connect to the probe at least once. also, if this has some kind of alarm I have literally never heard it. I have all the sound settings on in the app, and I would expect to work like any other alarm but it doesn't finally, if you don't immediately put the probe away you will constantly get notifications about its status.

Excellent app and excellent product. The graphing and 8 sensors really set this product apart and are unlike anything else on the market. Straight off the bat I was able to determine how my oven and air fryer were both under temperature and by using the predictive cooking tool was able to estimate cooking times and plan around that which is an extremely helpful built in feature. Incredible app, incredible hardware. I'm writing this as I watch a roast beef joint cool in real time from my desk.

Thank you so much for your review!

I'm so glad I bought this Combustion Inc predictive thermometer with the remote display. It is very easy to use! Now I don't have to wonder when the food I'm cooking will be done. I originally ordered one predictive thermometer with the display unit. It has been so accurate and simple to use, that I just ordered a second predictive thermometer. The remote display can run multiple predictive thermometers! Not having to run probe wires in my smoker and grill is great! Definitely worth the money.

Oh wow -- thanks for such a great review! Having two probes is great. Being able to predict two different temperature targets is a game changer when cooking different cuts at the same time. Thanks again for taking the time to share your review 🙏

What's new

Raises upper temperature (overheat) limit to 600ºF (315ºC) for the Predictive Thermometer, and adjusts related alarms on the Display + App.
Adds “game meat” as another option in the USDA Food Safe settings. (You’re welcome, Australia and Wisconsin.)
Includes newest firmware for Predictive Thermometer and Combustion Display.
Catches you up on any missed updates (such as important bug fixes, new Physics Engine, and USDA Food Safe feature).
