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!

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.

Making great pizza dough shouldn't take a spreadsheet. PieMinder does the math so you don't have to. Describe the pizza you want and it gives you the exact amount of flour, water, salt, yeast, olive oil, and sugar to use. Then it walks you through every step, from chilling the water to tossing it in your oven. No recipes to cross-reference. No conversions in your head. No "wait, how much flour was that again?" Just clear amounts and a calm set of steps. Never made dough before? The ten-step walkthrough uses your exact numbers and tells you what to do at each stage — it's hard to get lost. Been at it for years? Dial in hydration from 60% to 80%, change the crust thickness, or flip on gluten-free mode, and every number recalculates the instant you touch a slider. WHAT'S INSIDE • It does the math for you Enter pizzas, size, thickness, and hydration. Flour, water, salt, yeast, olive oil, and sugar (in grams and ounces) update the moment you change anything. • A walkthrough you'll actually finish Ten guided steps with your amounts built right in. Never a generic instructions that leave you cross-referencing an earlier recipe. Plus, the walkthrough remembers your last step! • Timers that come find you Mixing and resting timers live in app, the Dynamic Island, and on your lock screen. So you don't have to be left wondering when your next step starts. • Gluten-free mode A separate formula tuned for GF flour blends, with its own hydration range. • Share a recipe in a tap Send a link that opens your exact settings on someone else's phone, whether they have the app or not. • Made for iPhone and iPad, in light and dark. WHAT'S NOT INSIDE • No ads • No tracking • No accounts • No subscriptions • Nothing leaves your phone The calculator works fully offline. The only time PieMinder touches the network is the optional tip jar, handled securely by Apple. THE TIP JAR PieMinder is free, and every feature stays free. If it improves your pizza night, there's an optional "Buy me a slice" button. Five fixed amounts from $1 (a bite) to $5 (a whole pie). Nothing is locked behind it. It's just a thank-you. WHY IT EXISTS PieMinder started as a spreadsheet I kept reopening every Friday night; tweaking flour weights, recalculating hydration, scrolling back through a recipe with floury hands. Several years and a couple hundred pizzas later it became this app, so nobody else has to keep that spreadsheet. Built for the kitchen, not the spreadsheet. Make better pizza — starting tonight.
