Charlie M0PZT has released a FREE logging application for Android devices. It's designed for use with a tablet and QWERTY keyboard to allow for simple /P logging or in situations where a laptop (or pen+paper) are not convenient.
"As I cycle to all my /P locations, I don't like to take anything too large - That ruled-out my 15" Windows laptop and as my smartphone is too small the logical answer was a tablet. The one I have offers a 9" screen and cost £42. It works brilliantly... and I don't have to decipher my badly scribbled QSO notes when I get home!" Charlie M0PZT
picoLog creates an ADIF file as each QSO is made and this can then be imported into your existing Shack logging software.
