QSO Logger, ADIF & CSV Export
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
LogMaster is a ham radio logbook built for the way you operate: fast, always in UTC, and ready to export when you are done.
LOG A CONTACT IN SECONDS
• Type the callsign and tap Log Contact. The form stays open for the next call.
• Live UTC clock, with the band filled in from the frequency
• Reports start at 59, 599 or −10 dB depending on the mode
• A dupe warning when you have already worked that station today on the same band and mode
• Name, QTH and grid square fill in for US and Canadian callsigns
PARKS ON THE AIR
• Start an activation and watch the count to the 10 contacts you need
• Park-to-park references for the other station
• Export an ADIF file named and formatted for the POTA upload page
EXPORT AND IMPORT
• ADIF for QRZ, LoTW (signed with TQSL), Club Log and POTA
• CSV for Numbers, Excel or Google Sheets
• Import ADIF from other loggers. Contacts already in your logbook are skipped.
STATS
• Contacts, callsigns, bands and modes worked
• A twelve-week activity map, your best day and your longest streak
