We have covered a couple of interesting smart cups here in the past. The Yecup is a smart cup that lets you connect to it via Bluetooth to see the current the temperature of your drink and keep it warm. It can boil your drink and notify you when it is ready. You will be able to check the battery level of your mug and even take selfies using its special button. Did we mention that the cup has a battery to charge your phone?
The Yecup will be compatible with your phone, but the developers are already planning to build an Apple Watch app for it. You can find out more about this project on Indiegogo.
