You can check the water level via the app.
In the iKettle 3rd generation home page in the bottom left-hand corner is a box that says water, select this and the app will tell you how much water is in your kettle.
There will be the option of cups or basic.
Cups shows you how cups are in the kettle between 1 and 7.
Basic will show is the kettle is empty, low, half or full.
