HamBench is a native iOS utility for U.S. amateur radio operators. It combines reference data, study tools, and a real logbook in a single dark-themed app — with no accounts, no ads, and no third-party SDKs.
Core features work offline: FCC band plans, NCVEC exam pools, formulas, converters, CW drills, and local OpBook logging. When you're connected, optional integrations add repeater search and callsign lookup.
Browse FCC frequency allocations filtered by license class (Technician, General, Extra) or view the full chart. Quick reference for operating privileges.
Log QSOs with callsign, band, mode, grid square, notes, and timestamps. Contest mode for focused operating sessions. ADIF export and optional iCloud sync.
Study with official NCVEC question pools. Full exam simulation with realistic question counts. Study by topic or practice test mode for Technician, General, and Extra.
Practice Morse with send, copy, and Koch-method modes. Adjustable speed and audio feedback for brushing up or getting back on the air.
Interactive exam calculators and bidirectional unit converters (power, frequency, distance). Plus phonetic alphabet and Q code references for on-air work.
Live UTC time with local offset and day/night indicator — built for logging, DX, and contest work when you need the right time zone at a glance.
Search U.S. repeaters via RepeaterBook (free API token required). Filter by state, city, or callsign and jump to details on the web.
Callsign lookup via Callook. License class filtering. Alternate app icons and themes. Links to FCC, ARRL, and other official resources.
HamBench bundles FCC band plan and NCVEC exam data for reference and study. Always confirm operating privileges against current FCC Part 97 rules and official exam materials. Repeater and callsign data come from RepeaterBook and Callook when those features are used.
