The one major advantage with this would be to be able to enjoy the latest clock version without having to wait for your carrier to give their nod of approval when it comes to the most recent firmware update. In the updated HTC Clock app, it will arrive with a timer, stopwatch, alarm and a world clock that will do just about anything and everything expected of a clock app. This well-designed application is functional to boot, although it does not seem to play nice with a handful of HTC One (M8) models at the moment for one reason or the other, not to mention being broken on the HTC One (M7).
For those who are interested in picking up the latest HTC Clock app for their HTC smartphones, you will be able to get it here.
