For anyone who gets paid by the hour who needs to provide up to the minute detail on their work performance, a new app from Aussie developers Global Media Empire called Business Time lets you track location and work hours in the background of Android devices.
In addition to the GPS and timekeeping, you can easily add photos and voice memos to track your work performance, as well as emailing completed time sheets as CSV documents. Each task can be backed up and restored to SD card, meaning you can transfer between phones relatively simply.
There's a free version of the app which limits the number of projects to five, tasks to 50 and timers to 100, or a paid version for $9.99 which has no restrictions. And naturally, it will work seven days a week, not just Wednesday nights.
