Juicenet App Review

One of the reviews:

This app is janky on Android. The device settings screen frequently fails to load the properties of the charger, and forces me to fill in the address / etc. in order to change the amperage. The UI/UX is pretty bad when dealing with multiple chargers. It’s difficult to know which one you’re changing the settings for, and it’s hard to switch between chargers. The app frequently fails to load the charger data at startup, and presents me with the initial setup screens.
