Here is an app smart teapot that lets you brew tea like a pro. Telpo uses bio and environmental factors to better serve you. It automatically adjusts brewing temperature and time without you having to lift a finger. As the developers explain:
Teplo senses your heart rate, body temperature and other environmental factors like room temperature, humidity level, and sound level through proprietary sensors. Using these parameters, Teplo adjusts optimal brewing temperature and time.
You can place your finger on the heart rate sensor to get a personalized brew. The companion app has a database of 100+ teas for your to choose from. This smart tea maker is expected to ship in April.
