A Game-Changer for Precision Cooking
Color: Black
We’ve had the Typhur Sync Smart Meat Thermometer for a few months now, and it’s been nothing short of amazing. The wireless probe is a total game-changer, it frees you up from cords and gives you the flexibility to monitor your cook remotely. It charges via USB-C, which is super convenient. I can use the same charger that powers my smartphone to charge a meat thermometer, imagine saying that sentence 20 years ago.
The companion app is one of the highlights. It displays incredibly useful temperature data, including readings from multiple points within the probe to show the gradient of heat inside the meat. You even get a real-time graph tracking the temperature over time, which is especially helpful for monitoring the entire cooking process.
And best of all: the app is currently free with no subscription required (fingers crossed it stays that way).
The thermometer seems to be very accurate. While I haven’t tested it against lab equipment, the NIST certification and consistently reliable results give me confidence. I’ve made sure the temps fall within my personal margin of error—and so far, so good. I can’t speak for others who may have had issues with the probe, but from what I’ve seen, Typhur’s customer service has a solid reputation. I appreciate that they seem to genuinely stand behind their products.
While I primarily use the thermometer for reverse searing steaks, it’s versatile enough for anything from steak to turkey, chicken, or pork loin. If you’re serious about cooking and want precision without hassle, this is a fantastic investment.
Highly recommended.

This thing no longer working. Too late for a refund so the loss is on us. Buyer beware.
Color: Black
We wanted a temperature probe that was simple and works well. This one was it. We grill as often as possible and were just tired of having a good piece of meat come out either over or under cooked. I like a steak medium and my wife likes it medium well to well done. We use a Weber Genesis E410 that works great and has good heat control. Our first use of this Typhur thermometer gave us a great result. Not sure how it will work on a larger item like a brisket or a turkey but, at this point, we see no reason to expect any lesser result. It had accuracy, good range, and seems quite durable. Grilling is, among other things, is its own social event., so we did not use an "Ap" to watch the event on a smart phone. (We try to limit the use of smart phones when we are outside to encourage human interaction.) Typhur offers an Ap but the base unit was all we wanted to try and it works great.

Accurate and affordable
Color: Black
Four months after I purchased the thermometer, I have to say it is the best probe thermometer I have used. The temperature reading are accurate and the unit functions well. Very easy to use with or without the app. The display is easy to read but the app allows you to see all six temperature zones! Catch it on sale to get the best price. The probe battery only lasted six hours so I notified Typhur and they are replacing it without question! I purchased a second unit for a Christmas gift.

Great quality of life improvement!
Color: Black
Got this on sale for $40.
This thing is crazy good for the price, especially if you get it on sale.
Battery life isn’t a huge concern anyway, but rechargeable USB-C is great. Because it’s wireless, the stick is on the thicker side. This makes it easy to clean, but also inadvisable for your thinner meats (obviously). It looks right at home stuck on my fridge by the oven and air fryer, and temps it gave me through the phone were pretty close.
I connected this to my 2.4Ghz network, which I can easily monitor from my phone connected on my 5Ghz network. I think it could do better with its time estimates, but I’m physically close enough to my food when it’s nearly done cooking anyway.
I tested with frozen steak straight into the air fryer. It was quite close to what I was looking for, compared to how I’d do it before without a thermometer. As someone with little to no time to cook every day, it really eases the mental burden for sure of knowing that the food’s not under- or over-done. For $40, totally worth it.

Great engineering for amazing price
Color: Black
This is the deal of deals. The signal goes through my oven door with zero problems. The sensor inserts neatly into the controller slot. Nice. But that's not all. This thing is Gold Lite, and has the transmission frequency that is 10X better than Bluetooth. The App is probably same as the 4X higher priced Gold Edition, which is worth the price of admission. whose only advantage is that the sensor is good for 752F instead of 932F (yes the descriptions says good for 932F, but Lin the photo it says 752F) . The 932F is not anywhere good enough for my radiant ceramic grill, which goes up above 1300F anyway. So I saved a bunch of money and have something that does everything I need and no more.
For the price, this is 5 star
