Here is another smart coffee machine that combines with an app to help you brew pour-over, immersion and cold drip coffee. It also has a built-in scale, so you will get the water/coffee ratio right every time. The companion app guides you through the process.
GINA connects to your smartphone via Bluetooth. iOS and Android devices are supported. The app has a flavor wheel, drop meter for cold drip brewing time, and a whole host of other useful features.
