Ham Radio Companion

Version 2.0 — sync, formulas, and polish. • iCloud sync (optional): keep your exam history, statistics, bookmarks, logbook, and selected class in sync across your iPhone and iPad — even a quiz you're in the middle of, so you can start on one device and finish on the other. Off by default, stored only in your own private iCloud, and never visible to us. • Calculators now show their formulas the way a textbook would, with a "Where" card explaining every symbol • Settings is one tap away from every tab, and links open in a sheet you can swipe away • Fixed: Study by Topic could show the wrong questions on some devices, and two reference charts had misaligned column headers Since 1.0, Ham Radio Companion has grown into a complete study companion and toolkit: • A plain-language explanation for all 1,431 questions, with a tap-through to the exact FCC Part 97 rule • The full FCC Part 97 rules, searchable • Live band conditions from NOAA space-weather data, with an HF propagation guide • Morse (CW) trainer, a contact logbook with ADIF export, and nine calculators (Ohm's law, antenna length, LC resonance, reactance, decibels, wavelength, SWR, series & parallel, grid square) • Smart Review (spaced repetition), flashcards, and achievements • Ten reference charts: band privileges, phonetics, Q-codes, ham abbreviations, RST, emission types, CTCSS tones, resistor color codes, schematic symbols, and U.S. call districts • 26 original guides, a searchable 155-term glossary, and a Term of the Day • Home Screen widget and Siri shortcuts • Refined iPad layout and the 2026–2030 Technician pool Free, offline, and private — no account, no ads, no tracking.
