Starting a thread on useful Android Apps, so that we can not only post about the apps we found useful, but also ask fellow Android users on which app to use for a particular task. For starters, here are two apps that I loving at the moment: My Tracks: An app to record not only your GPS track, but also things like average speed, maximum speed, elevation etc. Haven’t used it much, but I like the interface and easy to use style. Google Goggles: Nice app to find out more info about things like books etc. seems to be decently accurate for the books I have checked with it. Now for the query, I am looking for a simple note application, which offers password protection for the notes.
