I haven’t used single arm to its fullest extent but have a great deal of success with using Siri voice commands to open apps and using the double tap to cycle through menus and start functions

Id be lucky to get more than half an hour.

If there was a sick mode, id love to get reminders every other hour to drink some water and reminders to log any painkillers to ensure i dont overdose/overlap in the hazy delirium of fevertown
