The best app to log your QSOs on the go.

Fast and efficient yet fully-featured: QRZ.com name lookups, QSO Maps, offline data files, contact rates, duplicate warnings, POTA spots, search parks nearby or by name, etc.

This app is still being built, so updates with fixes and new features are frequent. But this also means that things might break from time to time, so please bear with us.

Honestly one of the best apps I've ever installed. If you need to log specific radio activities, I can't overstress how much this makes life easier. Formats your log ready for upload. Auto handling of park to park and equivalents. Multi-activity in one. Built in spotting, hunting assistance. Wireless log export. And free - but I contributed anyway.

Favorite logging app for Parks on the Air. I like the operations settings features. It uses your GPS to locate the parks you want to activate within your current position and to set your Grid Square. The spotter tab list all of the active parks registered in the POTA App. You locate the park you want to log, click on it in the spotter tab, and it automatically switches you to the QSO screen and fills in the contact information for that activation. POLO is easy to use

So far, so good. Neat looking app that appears to have been built by competent software developers who ALSO know about amateur radio. Good lookup features (it found my maidenhead grid square easily, knew about POTA locations near my location, and can log-in to QRZ to do lookups). Downloads data to work offline. Ability to import and export logs. Haven't yet logged an operation …. but I'm definitely taking this app with me. 73 / M7SUX
