Ratings and reviews

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.

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 performance quirks, but nothing that restarting the app doesn't fix. It's been very reliable, no lost QSOs. 21/03/24: This app is working well for my quick test. I will try it out thoroughly for my next POTA activation. Simple and straightforward. Thanks!

September 30, 2020 I update the older version of this app and it rolled all my contacts back to 12-01-01 12:01a.m. 1970, newer version has UTC time option. But keep in mind if you have older version of this app leave it alone (user beware! on old version only ). Or you might have a roll back also like I had, on the newer updated version you should be good to go. Rick, KD9QDP.
