Yes, that means I can access all of my favorite desktop keyboard shortcuts on my phone. Need to select all? Function-A. Want to search a page? Function-F. Undo? Yup, I can do that, too. I can even hit Function-L in Chrome to jump to the address bar and immediately start typing in the site I want to go to.
That is something that I miss in my iPhone. The ability to press 'del' or undo.
I know that iPhones can alert the user when ambient noise levels exceed safety thresholds, and Apple Watches can detect and alert about detected falls, and even atrial fibrillation. I wouldn't be surprised if phone accelerometer signal processing could predict something like Parkinson's disease.
Unfortunately the best flashlight gesture experience in the business seems to be sold by Motorola. At least last I checked.
My friend liked mine and even found an Android app for trying it on his phone, but basically it was 3x slower than the Moto gestures version despite being on a much faster phone. Not sure why.
I have a K480 at the office for those random times I need to respond to something on my iPhone and don't want to deal with the crippling restrictions of an onscreen keyboard, and I hugely recommend it. With the keyboard almost every norm of macOS is supported.
