This is really useful if ever one of the keys stops working or you don't want to wear them out.
Assistive Touch's interface includes a circular button that you can use to access different features. All you have to do is tap on this circle and you'll see different parameters such as lock screen, notifications settings or any other feature that you want easy access to.
You can easily set up the features that appear inside the button with Assistive Touch. That's why you get to adapt the commands that appear when you click on the white button to meet your needs. Either way, it's really easy to set up the digital button panel as needed by accessing the settings.
Plus, the app is really useful if you want to manage different tasks using only one hand.
