Its not the greatest after bluetooth 4 as most bluetooth devices use a power saving mode that almost entirely turns off the bluetooth radio when its not in use. have had my computer lock itself purely because my phone turned it's screen off. if you stay within the confines of the limitations this app has, im sure it can be wonderful. but as an install and go app, there is plenty people would have to change to make this really useful.
It is now working with Mi band, I already got it paired with my laptop, but the blueproximity can't find it.
Seems to need a bit of work, works fine once you fiddle enough the settings. Fantastic idea with better then expected results.
Just use your mobile phone to lock and unlock your desktop, walk away ant it is locked, arrive at your desktop and it is unlocked, VERY good
