Pocket QSO Logger

Pocket QSO Logger is a free, offline-first logbook for amateur radio operators who log from their phone — at the desk, on a SOTA peak, or anywhere the radio goes. CW, SSB and FM by design. ◆ FEATURES – Session-based logging: one operation per station, rapid QSO entry, and last band / mode / freq remembered between contacts. – Bluetooth CW keyer: 9A5N QRQ and Pico keyers, six F1–F6 macros, Instant CW, and live WPM control. – Yaesu FT-857 / 897 radio control (CAT): live frequency + mode auto-fill the log; set frequency and mode from the app too. – cty.dat country / DXCC lookup (AD1C) with live flag, auto band from frequency, per-mode RST, and a real-time dupe warning. – Optional QRZ.com lookup for name, QTH, country and grid. – Maps with brass pins and great-circle paths — per operation and for your whole logbook. – Custom callsign keyboard, Indoor / Outdoor / Auto themes, ADIF share and full JSON backup. Free, no ads, no required account, no cloud sync. Optional analytics and crash reporting are off by default — decline them and your data stays on the device. QRZ.com credentials, if saved, are encrypted with AES-256-GCM via the Android Keystore. 73 and good DX.
