Sounds kind of useful, but imho I think most people dont want more devices to carry around, to charge, run updates, and whatnot, i also dont think many people would pay 25 bucks for that kind of device.
So the market for this kind of device is probably very small. Maybe sell it as luxury item? Who knows…
Also, maybe a smart watch could be used to fullfil this feature already?
