  1. 5/5Clean, simple, and completed

    I have used it only once so far, but I am deeply impressed by the quality of the app. In my experience, hardware like this gets crappy bottom of the barrel app support that barely does what it is supposed to and doesn't contain the deep levels of information I want it of them. This app cleanly and clearly shows all of the info you normally want out of the box and let's you dig in deep into a debugging display to get detailed sensor info. I haven't played much with the CSV export, but I expect it to be good as well.

  2. 5/5The BEST you can buy

    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.

  3. 5/5C Harbin

    I am a meat cooking nerd. I love the 8 temperature point reading and graphing feature of the Combustion Inc. thermometer. It takes keeping an eye on your grill to the next level! Knowing the ambient grill temp as well as the other temperature points throughout the item you are cooking is amazing! I have bought a couple more thermometers as gifts for my close friends and family that really appreciate precision cooking and the results!

  4. 3/5History please

    Edit: it’s been over a year now without having any cook history feature. Please let us save a cool or just export the data. That’s the only thing that I miss from a competitors product. I like everything in the app. Information is clearly laid out, graphs are great. But a cool history is sorely missing. I keep wanting to go back and check how long certain smokes took, when the stall happened with briskets, etc. adding notes to the cook would also be very helpful.

  5. 5/5A breakthrough!!

    Very satisfied with this. A small issue is the app can’t always find the device on the first attempt which just means I lose 10 seconds. Once it is connected it remains connected. Very accurate and easy to use It takes all the guesswork out of cooking

    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. Update now and experience the future of cooking monitoring!
