WillisLogger · amateur-radio logging
The only full-featured ham logbook that runs natively on
every device you own.
Mac, Windows, Linux, iPhone, and Android — the same app, the same log, online or off. No server, no subscription. Your log stays yours. Pay only for the platforms you use.
The whole logbook in eight minutes
A full pass through the app as it stands today, recorded against a real log — QSO entry and live lookup, POTA and contest modes, the map and awards dashboards, and log sync. Jump to the part you care about.
Nothing loads from YouTube until you press play — or watch it on YouTube instead.
Full-featured and everywhere — the combination nobody else offers
Every other logger makes you choose. The feature-rich ones — MacLoggerDX, Ham Radio Deluxe, N1MM Logger+ — are each built for a single platform family. The ones that truly run everywhere are deliberately streamlined field loggers. And the full-featured “runs anywhere” option is a web app you host on your own server, which is little help at a park with no signal.
WillisLogger is the only logbook that is all of these at once: full-featured, native on all five platforms, works offline, needs no server, and requires no subscription — with your log stored in a local file you own.
One app, three promises
Everywhere, natively
The same native app and the same log on Mac, Windows, Linux, iPhone, and Android. Installs and runs offline — from the shack desktop to the phone in your hand with no cell signal.
Full-featured, not stripped down
Live callsign lookup, real-time dupe checking, POTA / contest / Field Day modes, RBN band map, DX cluster, grayline world map, awards, statistics, rig control (Hamlib + FlexRadio SmartSDR), WSJT-X logging, and LoTW / eQSL / QRZ / Club Log sync.
Yours, and fairly priced
Local database, clean ADIF and Cabrillo export, no account, no telemetry, no subscription — and you pay only for the platforms you actually use.
Everything a busy operator watches at once
Entry, spots, log, map, awards and stats — the real WillisLogger desktop app on macOS, dark and keyboard-first.

Your log belongs to you
Every QSO lives in a standard SQLite database on your machine. No account, no telemetry, and it works fully offline. One click exports clean ADIF or Cabrillo — the formats the whole hobby speaks — so you can move your data anywhere, anytime. Optional sync to QRZ Logbook, Club Log, LoTW, and eQSL uses your own credentials and stays off until you turn it on.
“Log the contact, not your credit card. WillisLogger keeps your logbook on your device and speaks the formats the hobby already trusts.”
