WillisLogger: Ham Radio Log

Log QSOs your way: fast, private, and offline-first. POTA, contests, DX chasing, awards, live maps, and rig control in one app—no account, no subscription.

WillisLogger is a local-first logging application built for licensed amateur radio operators — POTA and SOTA activators, DX chasers, contesters, and everyday loggers who want a fast, modern, private logbook that works the same on every device.

Your logbook lives on YOUR device. Contacts are stored in a local SQLite database. Nothing is sent anywhere unless you deliberately enable an online feature and enter your own credentials. No subscription. No cloud account required to log. No ads, no analytics, no trackers.

LOG FAST • Auto-uppercase callsigns, a live UTC clock, and real-time duplicate (DUPE) warnings. • The full extended-ADIF field set — name, QTH, grid square, DXCC, state, zones, power, POTA/SOTA/WWFF/IOTA references, QSL/LoTW/eQSL status, and more. • Virtual "logs" to organize contacts by activation, contest, or event. • A command palette for quick, keyboard-driven navigation on desktop; a fully touch-adapted interface on mobile.

KNOW WHO YOU'RE WORKING • Callsign lookup via QRZ.com, HamQTH, and HamDB with an opt-in priority chain and an offline callsign database. • DXCC entity resolver and a callsign info card with photo, flag, distance, and beam heading.

CHASE AND POUNCE • Live POTA, DX cluster, and RBN spots with click-to-fill and click-to-QSY. • Needed-multiplier highlighting and a visual bandmap. • Rig control via Hamlib (rigctld) or FlexRadio / SmartSDR — frequency, mode, S-meter, and tune. (Rig control is network-only on mobile.)

OPERATING MODES • General, POTA (activation and hunter), Contest, and ARRL Field Day. • Live score, multiplier, and dupe tracking. • A data-driven contest library plus a user-defined-contest editor. • Super Check Partial and call history for confident copy.

SEE THE BIG PICTURE • Awards dashboard: DXCC, WAS, WAZ, WPX, WAC, IOTA, VUCC, grids, zones, continents, and POTA — worked vs. confirmed, by band and mode. • Live world map: worked stations and spots, greyline, and great-circle paths. • Statistics dashboard with charts. • Solar and propagation indices with live HF band conditions, plus DX alarms and alerting. • Satellite tracking: pass prediction, ground-track and footprint overlay, and satellite QSO logging.

IMPORT, EXPORT, AND SYNC • Import and export ADIF, Cabrillo, POTA, CSV, and KML. • QSL card and label printing. • Optional online logbook sync: QRZ Logbook (upload and download), Club Log, LoTW, and eQSL. • WSJT-X UDP logging and automatic backup/restore.

ONE LOGBOOK, EVERY APPLE DEVICE WillisLogger runs on iPhone, iPad, and Mac — the same logbook and the same workflow wherever you operate. It's the companion logger to WillisSDR.

WillisLogger is for licensed amateur radio operators. A valid amateur license is required to transmit.
