Everything You Need to Log QSOs
Whether you're operating portable, at home, or chasing DX — QSL Buddy has the features to make logging fast and effortless.
Core Logging Features
Designed for speed and simplicity
Quick QSO Logging
Log contacts in seconds with minimal typing. Smart prefix suggestions for VHF/UHF local contacts, quick-select RST buttons, and automatic country detection from callsign prefixes.
Smart Prefix Suggestions
On VHF/UHF bands, QSL Buddy remembers your last contact's prefix and suggests it for the next contact. Perfect for logging multiple contacts on the same repeater or local net.
RST Quick-Select
Tap to select RST reports instead of typing. Common values (51-59) are just one tap away. Both sent and received RST are tracked.
Automatic Country Detection
Automatically detects the country from callsign prefixes using ITU zone data. Helps you keep track of DX contacts and confirmations.
Logbook & Sync
Your contacts, organized and accessible everywhere
Full Logbook
View all your contacts in a searchable, filterable logbook. Sort by date, callsign, band, or mode. See your contact history at a glance.
ADIF Export
Export your logbook to standard ADIF format for upload to LoTW, eQSL, QRZ, or any logging software that supports ADIF (like Log4OM, DXKeeper, or N3FJP).
