QSO Log: Ham Radio

QSO Log is a private, offline-first ham radio logbook for recording contacts quickly and keeping your data under your control. Start with the callsign, then capture UTC time, band, mode, frequency, signal reports, location, grid, notes, station profile, tags, and activity references.

Built for the shack and the field:
• Log QSO contacts with the details that matter: callsign, UTC time, band, mode, frequency, and signal reports.
• Search and filter your ham radio log by callsign, band, mode, date, tag, or station profile.
• Reuse saved station profiles for home, portable, and field-day operating.
• Recover an interrupted entry from an autosaved local draft.
• Edit, duplicate, archive, and delete contacts with clear confirmations and Undo.
• Export ADIF or CSV files to a location you choose.
• Preview ADIF imports and possible duplicates before anything changes.

Private by default:
• No account required.
• No ads or analytics.
• Core logging works offline.
• Your QSO data stays in app-private storage until you choose to export it.
• No location, camera, microphone, contacts, or notification permission is required.

QSO Log Pro is an optional one-time purchase. It unlocks unlimited contacts, logbooks, and station profiles; reusable entry templates; tags and advanced filters; private on-device insights; printable PDF summaries; and checksummed local backup creation. Core logging, ADIF/CSV import and export, and restore of an owned backup remain available in Free.

QSO Log creates local records and user-controlled files. It is not affiliated with ARRL, QRZ, LoTW, POTA, SOTA, a radio manufacturer, or an award program, and it does not submit records directly to third-party services. You are responsible for record accuracy and for any external submission requirements.
