Session QSOs
Tap a QSO to edit or delete it on the Log tab. Contest and POTA/SOTA QSOs are in your main logbook and QRZ export too.
Upload to QRZ.com
0 QSOs not yet uploaded.
-
Save the ADIF file with your new QSOs.
On iPhone choose Save to Files; on Android it goes to Downloads (or pick Drive / Files in the share sheet).
- Open your QRZ Logbook and sign in (a free QRZ account works).
-
Import the file: in your QRZ Logbook open Settings and click Import under
“ADIF Import/Export” (or use the Import/Export Tools button at the top right → Import from ADI File).
Tap Choose File, pick the
.adifile you saved, then Import ADI File. QRZ processes imports in the background – give it a minute, then refresh your logbook. -
Confirm: once the QSOs show up on QRZ, mark them as uploaded so the next export only contains new ones.
Upload status tools
Use these if HamLog and QRZ got out of sync.
QRZ treats an imported QSO with the same call, band and mode within ±30 minutes as a duplicate: it replaces the existing record (confirmed records are left alone), so re-uploading does not create double entries.
Callsign lookup
Each filled field shows where it came from. Offline, only the prefix country is used.
Logins (stored only on this device)
If you leave a password box empty, the saved password stays as it is. A password manager can fill these forms.
Encryption, auto-lock & backup
Without a passphrase, logins are kept for this tab only (session-only) and are gone when it closes. With one, they're encrypted (AES-GCM; key from PBKDF2-SHA256, 600,000 rounds) and saved on this device.
Test a lookup
Import ADIF
Merge QSOs from another logger (.adi / .adif), or a QRZ logbook export if you have a QRZ subscription. Exact repeats (same call, date, time to the minute, band, mode) are skipped.
Backup & restore
Your log lives only in this browser on this device. Back it up regularly.
