How can I check if installed apps are latest versions? I used to have an app on my Desire HD that I think was called Something Dog. When launched, it would list all the installed apps and whether they were the latest versions.

My Desire HD crashed a while ago, and all my data was lost. I've since bought a One X and I'd like to have this app again.

Does anyone know what it's called?
The "dog" you are talking about is aTrackdog. :)

It queries your installed apps and compares them to the latest known versions.
