HamFinder is a free Utilities app for iPhone and iPad that makes callsign lookup simple: one search, then save the callsigns you care about for later.
I built it for everyday ham radio use under callsign KO6CNT — less hunting through bookmarks, more keeping a short list of operators you actually talk to. Search, favorites, and a small focused UI; nothing more than it needs to be.
Key points
- Callsign search from a single field
- Save favorite callsigns for quick reference
- Free on the App Store for iPhone and iPad
