## What is Combustion Inc.?

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. 

Live Activity/Apple Watch support. The Combustion App works with iOS as well as iPadOS and MacOS (M1 or newer). Includes Live Activity (Dynamic Island) display feature so you can watch key temps even when the app is in the background. So handy!

Combustion App Features:

– Set target temp: so that your food comes out just the way you want it
– See predictions in relative time (“ready in” countdown) or in absolute “clock” time
– See key temps in real-time: including TrueCore®, TrueSurface™, TrueAmbient™
– Get notifications for important cooking events with advanced alerts (ready alarm, 5-minute warning, disconnect alert, low battery notification)
– Set SafeCook™ parameters (integrated food-safety)
– Know exactly when your food is safe to eat 
– Set-up WiFi connectivity for Combustion WiFi accessories
– Graph your food’s temperatures in real-time!
– See (and graph) temperatures from all 8 sensors with Advanced Cooking Mode
– Enables multi-node MeatNet™: use any combination of Combustion accessories to extend Bluetooth signal range + strength
– Use with or without Combustion Display
– Export cooking data - to fine-tune your technique
– Update firmware: get better performance and new features for Combustion tools
– Works with most cooking appliances and cookware types
– Works with all kinds of foods and most cooking appliances - BBQ smokers, ovens, ranges, grills, and more - indoors and out.
– Works with or without WiFi

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.

### 5/5 — The BEST you can buy

*2026-07-09, version 3.2.1*

Combustion Inc makes the literal best products. High quality, reliable, straight forward, and every detail was thought through carefully. I find the meters are always connected when they should be, the temperature readings are always accurate, and the app works flawlessly. I couldn’t be happier. I’ve used all kinds of products in this space and they all have their faults. I can’t find a single fault for Combustion Inc.

### 1/5 — Terrible

*2026-07-04, version 3.2.1*

Can’t get devices connected. Instructions aren’t correct and app is worthless.

### 5/5 — Awesome product

*2026-07-01, version 3.2.1*

Really love the thermometer, and Chris' YouTube science to go with it. Would be cool if the app had some extra features like saving graphs for historical comparison, an API to consume data for whatever you wanna do with it, maybe social features to share with other cooks what you're cooking with it.

### 1/5 — Poor

*2026-06-30, version 3.2.1*

The website is awful.  My new thermometer arrived missing the charger.  The email to “help” is not active.  The instructions are poorly written. The app is frozen. 
Need I say more?
Waste of time and money

### 5/5 — 5 star

*2026-06-21, version 3.2.1*

Probe is thin and easy to insert. Whole ecosystem just works. It’s next level. Recommended.

### 2/5 — Title

*2026-05-23, version 3.2.1*

Having to uninstall and reinstall the app every single cook is very frustrating, especially at the price point….but the thermometer works after you do so

### 5/5 — Like it so well, I bought one for my son

*2026-05-22, version 3.2.1*

Love the gauge.  I’m having trouble getting the temp probe to work.  Once I figure this out it will be perfect!

### 5/5 — Great Thermometer

*2026-05-18, version 3.2.1*

I really like my combustion inc thermometer. It’s improved my ability to cook meat tremendously. I’d really like to save my favorite presets for different target temps though. Please add.

### 3/5 — Did my probe break?

*2026-05-05, version 3.2.1*

The ambient temperature reads ‘no data’ after I used it on the grill.  I thought the probe could withstand temperatures up to 900 degrees.  The website shows it being used on the grill  in a steak.  Did my probe break down?

### 5/5 — Data Informed Cooking

*2026-05-02, version 3.2.1*

Love this system and use it for everything. Seeing multiple temp data points in real-time visualize the heat and evaporative cooling process…mind blown. Seeing the resting process after cooking and the temp increase before peak internal temp occurs, super cool. Csv export is a very nice touch and testament to science. Well done.

### 3.0.0 — 2025-09-02

Welcome to Combustion 3.0! We've completely redesigned the main device interface to make managing your growing collection of Combustion tools easier and more delightful.

- Beautiful New Device Cards Interface.  Say hello to our gorgeous new device cards featuring fun temperature gradients that let you track your cook progress at a glance. No more squinting at numbers – the visual temperature gradient gives you instant feedback on how your food is progressing. It's like having a heat map for your meal!

- Better Device Management. With more Combustion devices hitting the market, we needed a smarter way to help you distinguish between them. Updated device graphics and clearer layouts make it easy to identify your Predictive Thermometers and Giant Grill Gauges at a glance. Perfect for when you're managing multiple cooks or have multiple devices.

- Performance Improvements. We've significantly improved app performance, especially for those marathon cooking sessions. Whether you're smoking a brisket for 16 hours or doing a long sous vide cook, the app will stay smooth and responsive throughout your entire cook.

- Design Polish That Actually Matters. We've optically centered the degrees unit toggle (because we're perfectionists like that) and moved the graph x-axis labels to the left edge for better readability. Small details, big difference in usability.

- Latest Firmware Updates. Includes Giant Grill Gauge firmware 1.0.6 with the latest performance improvements and bug fixes.

- Setting the Stage for the Future. This new interface gives us incredible flexibility for upcoming features. We're already working on a simplified view for managing multiple devices while cooking, enhanced data visualization tools, and exciting alarm features. Giant Grill Gauge users can already enjoy high/low alarms, and we're bringing this same functionality to Predictive Thermometers soon with support for setting alarms on any sensor.

This is just the beginning of our journey toward a richer, more intuitive cooking experience. Version 3.0 lays the foundation for some truly exciting features coming your way.

Giant Grill Gauge support with new merge flow! The Giant Grill Gauge works seamlessly with the app, including proper high-low alarms and all connectivity improvements. High-low alarms are coming to Giant Grill Gauge first, with Predictive Thermometer support following soon.

You can now collapse the offline devices section to keep your interface cleaner and more organized.

Export incomplete CSV data with warning labels so you know exactly what you’re getting when exporting partial cooking sessions.

Plus various bug fixes and performance improvements that make the app more stable and responsive.
