希望支持旧设备ipadmini 2

想充分利用旧设备,可惜不支持,ipad mini2 最多只能升级ios12,希望开发者能支持,让旧平板利用起来

Incredible with some lags and pencil support issues. 9.8/10

Incredible with some lag sometimes. I've experienced noticeable latency even on fast mode sometimes. Apple Pencil support could be more improved. It would be better if there were an option to make my hands zoom in/out rather than a mouse, because it sometimes mess up when I use my Apple Pencil. Still, this is such an amazing app, keep up the good work!

Amazing piece of software

Used the app to revive usage of old hardware that doesn’t support sidecar, using this to make my iPad 5th gen into a second monitor for chatting and guides while gaming Works easily and smoothly and it’s free!
