Ham Logging

Ham Logging is a comprehensive QSO logging app for amateur radio operators. It serves as a master log that syncs with the most popular ham radio platforms — LoTW, eQSL, ClubLog, QRZ.com Logbook, HRDLog.net, CloudLog, Wavelog, N1MM Logger+, and more — so you keep one log instead of juggling many. Available on both Android and iOS.

KEY FEATURES

• Full ADIF 3.1.4 import and export with spec-correct UTF-8 length prefixes

• CSV and JSON round-trip backup across every stored field

• QRZ.com lookup with auto-search, profile photo, and local cache

• 21 logging-service integrations: 10 with live API, 11 export-ready

• Incremental sync — never re-uploads what you have already sent

• Bidirectional LoTW / eQSL / ClubLog / QRZ / CloudLog / Wavelog

• N1MM Logger+ UDP bridge on your local network

• Rover Mode: large-target, voice-dictated callsign entry for mobile operating

• POTA, SOTA, WWFF, contest, and propagation-mode fields with dedicated UI

• Per-QSO QSL card export — themed, code-rendered PNG

• Monthly and yearly statistics with shareable bar-chart images

PROPAGATION AND MAP

• World map with great-circle bearing lines to every worked station

• Gray-line terminator overlay with aurora layer (NOAA OVATION)

• 24-hour MUF prediction with band openings

• PSK Reporter and WSPR path prediction heatmap

• Live solar terrestrial data and band-by-band DX potential

• Unified Spots tab — DX cluster, POTA, and contests in one place

PRIVACY-FIRST

• No accounts, no ads, no analytics, no third-party tracking SDKs

• All QSO data stays on your device — sync only happens when you tap Sync

• Microphone permission is used only by Rover Mode voice dictation; audio is processed by Google Speech and never recorded or transmitted by Ham Logging

• On Android devices without Google Mobile Services (some Huawei configurations), the app surfaces a clear message and falls back to manual callsign entry

DARK MODE + ACCESSIBILITY

• Theme-aware throughout — every dialog, panel, and chart respects dark mode

• Font-scale slider for global text sizing

• Tips & Tricks — 100 rotating contextual hints, toggleable from Settings
