Ratings and reviews

simple and functional user interface, easy to use and navigate. Ability to customize the data display is a plus. Though not as fully featured as the PC based logger I usually use, it does the basics and is a good alternative when I am without a PC

25/11/09: Haven't used since major update. 23/07/16: 100% reliable. A very good logging app. 22/01/10: I've been using this app as my primary logger since my previous review, for around 150 POTA activations and other misc activity. Fantastic app! There's a few quirks, but nothing that restarting the app doesn't fix. It's been very reliable, no lost QSOs. 21/03/24: This app works well in my quick test. I will try it out thoroughly for my next POTA activation. Simple, straightforward. Thanks!

Nice and easy to use... But the issue with time&date (local instead of UTC) is more than just an inconvenient. And although many reviewers have pointed it out, there's no reply whatsoever from the developer. I hope he/she is ok, and maybe in the near future there is an update or a fix.
