I found this to be convenient, as my temperature preference changed depending on the type of drink I made. Out of the box, the Ember Mug is preset to bring drinks to 135 degrees, but you can change this to your preferred temperature, selecting anywhere from 120 to 145 degrees. I haven't had too much luck with this feature yet-there seems to be a delay in communicating the info, so I haven’t been able to see my caffeine intake recorded in the health app.

Doing so will allow the Ember app to share information with the health app regarding how much caffeine you’ve been consuming. The app also has several tea timers for making green, black, and herbal tea, and the app will send you a notification when the tea has finished steeping.įor a more involved use of the Ember app, you can connect it to the health app on your phone. There’s also an option to create a personalized preset enter the drink type, temperature preference, and brand (limited options available). Scrolling up on the temperature screen allows you to access preset temperature settings for black tea, green tea, coffee, cappuccinos, and lattes, and tapping one of these options will bring your drink to Ember’s recommended temperature. Another nice feature of the app is that it notifies you when the ideal temperature has been reached, but of course, the LED light does that, too. For future cups, all I had to do was open the app, and the temperature automatically popped up on the screen. The app took me to a screen with a temperature gauge that changes from a light gray color gradient when the cup is empty to orange, indicating that the cup is in use and has an increased temperature. Since I own two different Ember Mugs (this classic version and the Ember Travel Mug²), I had to select the device I was using at the time to appropriately connect. When you open the app, a prompt will come up, and all it takes is a single tap to connect to your Ember Mug, which then has a number of personal settings. I was able to see and adjust the beverage’s current temperature via the Ember app, which I thought was easy to use and well-designed. Then, I simply turned the mug on and poured my beverage of choice inside. The app guided me through the setup process in a step-by-step manner.

To do so, download the Ember app onto your Android or Apple device. Once charged (which takes about two hours), the Ember Mug is ready to be paired with a phone. Prior to using the Ember Mug for the first time, I had to charge the mug by placing it onto its charging coaster, which gets plugged in via the AC power adapter. Underneath the logo is a smart LED light, which flashes in a solid white to indicate that the perfect temperature has been attained. (The 14-ounce Ember Mug measures 4.6 inches tall and 3.46 inches wide, again with a 4.4-inch coaster.) Weighing 14.5 ounces and measuring 4.2 inches tall x 3.3 inches wide (not including the handle), the 10-ounce Ember Mug is similar in weight and size to a basic ceramic mug, and it charges on its 4.4-inch matching coaster.

I found that this coating closely resembled the feel of a ceramic mug and therefore didn’t affect the flavor of beverages like stainless steel can, which was a major plus in my opinion. The Ember Mug comes with a sleek matching charging coaster and is made of durable stainless steel with a ceramic-reinforced coating. I tested the second-generation Ember Mug² to see how long it could keep hot liquids warm, how it works with other beverages, and how well the mug and app are designed. This smart mug warms hot beverages (whether coffee, tea, or another drink) to maintain the ideal temperature much longer than your average ceramic cup. But finally, there’s a solution: the Ember Mug. Unfortunately, coffee can only stay hot for so long before it quickly loses heat. There’s nothing quite like a hot cup of coffee in the morning-something about its warmth is both calming and comforting as you begin the day.

We purchased the Ember Mug² so our reviewer could put it to the test.
