Range cooking thermometer for iPhone and iPad

Every cook can use an assistant to cook a succulent turkey, hit firm ball on the nose when making caramel, repeat your best homebrew recipe, or execute a perfect New England roast. Range can help you achieve great results with less effort.

Precise temperatures, raw speed

Grill it your way to get as tender as you like without sacrificing food safety. Leave Range in or spot-check doneness quickly.

Connect your food to your phone

What makes Range a smart cooking thermometer? The Range app for iPhone, iPad, and iPod touch. It gets a calibrated temperature reading from your Range thermometer, and comes with USDA- and gourmet-recommended presets for meat and candy, Fahrenheit and Celsius scales, notifications that are pushed to all your iOS devices even if they're in another city, and a graphing mode to record your experiments.


Rangefinders monitor specific temperature bands for meat, candy making, homebrewing and more. Save, share and compare results as a PDF or CSV file.


Get remote alerts with sound sent to all of your devices. The Range app remembers so that you can focus on dessert.

Remote alerts

Get alerts on all your devices, limited only by your Internet connection. Step out for sides and still know when dinner is perfect.

Gourmet materials, gourmet results

Food-safe silicone and stainless steel mean that Range can hang with any utensil. The handle clips onto pots for hands-free cooking, and the 4.5’ silicone cable is tough enough to stick in the oven.

SDK for developers

With the free-to-use Range SDK, iOS developers can add support for the Range hardware to their own app. With the included library and example app, you can start reading precise temperatures in a few minutes. The example app includes an HTML template to make simple apps fast and easy — if you know HTML and can press the Run button in Xcode, you can make a temperature-reading app.
