The IKAWA Home Roasting System is designed to work with the IKAWA Home App, where you will be able to choose, customise and monitor your roast recipes.
However, when you are repeating a roast recipe that was already sent to the Roaster, you do not need the app. The Roaster stores the last recipe sent – simply push the go button and run the latest recipe as many times as you like without any inputs from the app.
