SMS Backup: Application review

Here is an interesting useful application that I got after I asked a question on android developers group. I had almost started developing this application that would backup the SMS messages on the device to the GMail account.

Essentially the application is called SMS Backup, one can search this application with this string in android market. Once downloaded and installed you need to setup your google account in the application and make sure that google account is IMAP enabled.

After this simple setup, your SMS messages would be backed up to the GMail account under a label SMS. This also can be changed from the application settings.

Currently it seems that the restore functionality is missing. I would have liked to have that functionality as well.

I would still recommend this application to everybody.

My Tracks: Application Review

Finally an application that I was long looking for. I used to use sportstrack application on my N95 to log my GPS tracks and use the logging data for photo tagging. There did not seem to be any equivalent application on the Android.

The application My Tracks solves these problems, one can start the application and it will log all the GPS information. I find the application simple. At the end of the track recording the application would upload the track to google maps and google docs. One can use the data for any purpose after that.

The application also provides option to log statistics while the upload of the track and one has access to this data also on the google. The application can run in background and in limited use that I have done with it, did not seem to overburden the battery.

The application has features of exporting maps via KML files or GPX files which comes handy since I use gpicsync for photo synchronization. The only strange things is that these options are buried under "Share with friends" option. I can live with that.

I would recommend this application to pretty much everybody.

Once the phone powers up, you are upgraded to the RC33 equivalent version. To verify the upgrade, go to settings, About Phone and check the build number, it will show holiday_devphone-userdebug 1.1 UNLOCKED 130444 test-keys.  Another sign of the fact that the phone is updated is a new menu item called System updates in the About phone menu.
