Screen usage - screen on timer

[Brentdangerfield]

Hi there. I'm trying to find an app that tells me how long my screen has been on, and displays the info in the notification bar. It's for productivity purposes, but I don't need another app stuffed with loads of pointless stats. If I have a little timer that always counts away as I'm using my phone, I can see exactly how much time I've spent using it and can fully myself into doing something else. Any ideas? Thanks in advance.

You want an app that hasn't been written for Android - a billing time app. Sorry. (If the business is developing software, learn Java, learn the Android environment, and write a billing app - allowing the user to switch clients on the fly [and keeping 5 or 10 in the app at once]. It will most likely sell. But most people use a PC (or a laptop if they have to be on the move) for that purpose - there have been programs for doing that almost since the first version of DOS came out, around 1981. (Maybe even in CP/M - it's been too long to remember.)
