Bad user interface.
This app has such terrible UI. It essentially has 4 buttons of which one is programs (and gives a description of the types of). Session. Which leads you back to the main page- asks you to connect your device. Predefined which also asks you to connect your device. And Setting which gives you a snapshot of your past usages. It is impossible to use the app to change programs. I’ve been stuck using the same program since I bought it a year ago. Every time Im determined to figure it out- I’m left frustrated.
