QSOSlate

About

QSOSlate is a private, offline amateur radio logbook for iPhone and iPad. Record contacts in strict UTC, preserve corrections without erasing history, and carry your log into other tools without an account, subscription, advertising, analytics, or cloud dependency. • Save station profiles with call sign, Maidenhead grid, equipment, antenna, power, and notes • Freeze station details into one active operating session and log contacts continuously • Record call sign, band, mode, frequency, signal reports, grid, QTH, power, and notes • Detect possible duplicates while allowing an intentional save • Append immutable revisions, void or restore records, and retain the complete audit trail • Search and filter history, then review deterministic band, mode, call, and active-day facts • Import and export ADIF while preserving unknown fields; export CSV or readable text • Create checksum-verified backups, preview conflicts, merge or replace, roll back, and recover safely Your stations, sessions, QSOs, and backup files stay on your device unless you explicitly export them. Only feedback you choose to send can use the network. QSOSlate does not include online call-sign lookup, maps, cloud sync, contest scoring, radio control, or regulatory advice.
