As the last reply indicated, atrackdog will update all your apps. it's easy to use so I update at least a couple of times a week
I dunno. The version of aTrackDog that I have won't update any of my apps. All it will do it tell me which ones have updates available (including unreleased alpha and beta versions). It then lets me click on each one, individually, just like in the MarketPlace, and update them, each one, individually.
It's often easier and quicker to go to the MarketPlace, hit menu, downloads, and there you go, all of your apps with updates right there at the top, ready to be updated.
If you install an app, then back it up to the SD card, then uninstall it, aTackDog will update the backup on the SD card, even though the app is no longer installed. That's a good thing. But for regular backing up and keeping track of your apps, aTrackDog is deeply flawed in many respects. Those using aTrackDog would do well to read this
(aTrackDog flawed and deceiving | Android Community) very carefully, particularly the last paragraph. Keep in mind that is does more than just tracking
your apps on
your phone. It actually uses
you to keep track of how many people are running apps, and which apps they are running.
