Both models: 2-year warranty, 30-day returns and the free Hehku app.

The temperature keeps rising after the food comes off the heat. Hehku calculates this carryover cooking in advance and alerts you at the right moment, so meat, fish or chicken reaches the table at exactly the temperature you wanted.
Send a live link and family and friends can follow the cook in their browser or in the app. You can also share a thermometer permanently with another Hehku account, such as your partner's.
Apple Watch and Wear OS watches show the temperature and the time left, and you can dismiss alerts right from your wrist.
The repeater in the dock extends the range to about 50 metres, so you can step away from the grill. A cook shared with a live link can be followed online from anywhere, as long as a phone or Hehku Bridge stays within range of the dock.
The sensor sits on a cable rather than in the probe's handle, so cold meat can't drag the reading down. Clip it beside the food and it reads the heat the food is actually cooking in. A separate sensor is the only way to measure the chamber accurately in every situation.
Three steps, from beginner to pro.

Push the thermometer into the meat and put it on the grill, in the oven or in the smoker. The dock goes next to it.

The app shows the temperature and the time left on your phone or watch. No need to stand by the grill.

An alert tells you when to take the meat off the heat and when resting is done. Slice and enjoy.
Shared cooking
Send the cook as a link. A friend, your partner or the grill master next door sees the same temperature, stage and estimate that you do – in a browser or in the Hehku app.
Start the cookPick what you are cooking and how you want it, as always.
Share a live linkChoose at the same time whether they can only watch or also change the target and the alerts.
The link opens in a browserNo app and no account needed. The link works on a phone and on a computer.You can also share the thermometers permanently with another Hehku account, a partner for example. They then see your cooks without a separate link and get the alerts in their own language. Your own phone and tablet see the same cook without any sharing, as long as both are signed in to the same Hehku account. A second phone can also act as a bridge. Leave it at home near the thermometer, and follow and adjust the cook on your own phone wherever you are.
Our customers keep their thermometers: fewer than 1% are returned. Read the reviews and see for yourself.

Set up your own alerts to match the way you cook.

On Android each thermometer appears in the notification bar, and on iPhone in the Dynamic Island and on the lock screen. You can also follow the cook on Apple Watch or Wear OS.

Two internal sensors measure the core temperature accurately, and the slim 6 mm probe slides easily into meat.

A separate sensor clips on beside the food and reads the heat of the grill or oven up to 350 °C. The app alerts you when the heat drifts.
The ceramic end of the probe withstands 500 °C (932 °F), so you can grill over an open flame too.
