The Ham Radio Logbook App is a simple, yet very effective way to keep track of your ham radio contacts, as well as your ham radio activity. It provides an easy and user-friendly interface to keep track of all your log entries, and it allows you to export your contacts as an ADIF file, which can be easily imported into another Android device.

If you have a number of stations that you frequently use, you can save them in the app so that you can easily set up a quick contest entry, and you won't have to remember the frequency, power, and mode.
