QSOSlate

Log amateur radio contacts quickly in strict UTC, preserve auditable corrections, and carry your private records into any ADIF, CSV, text, or verified-backup workflow.

iPhone and iPad
Local-first

Fast logging stays ready off the grid

Freeze your station details into an operating session, then record call sign, UTC, band, mode, signal reports, frequency, grid, power, and notes without a network.

Corrections never erase the original fact

Search and filter history, detect possible duplicates, append immutable revisions, void or restore a QSO, and review deterministic band, mode, call, and activity-day facts.

Your log remains yours and stays portable

A USD 0.99 App Store download includes ADIF round trips, CSV and readable text exports, checksum-verified backup, conflict preview, merge, replace, rollback, and recovery.

Privacy
