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.

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

Excellent App! I can't rate this app highly enough for logging portable operations. I mostly do POTA with a bit of WWBOTA and SOTA and it does everything I need and more! There are loads of nice features such as QRZ lookups, which mean I can greet the other operator by name during a QSO, and spotting. Keep up the amazing work, folks! de, M9LVY

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
