This update from Apple will improve the functionality of this app. No new features are included.

Fixed a bug that made it difficult or impossible to connect to PC on some network setups.
Should be much easier to connect for some users now.

Added a button to lock the screen to prevent unwanted taps.
Locking the screen also dims the screen to save battery.

No more mode switching from phone, it’s all done on PC now.

Ability to join a Secondary PC server now enabled on iPhone. Install PocketStrafe on another device and try it out using 2 phones at once -- one in each pocket!
