# VU3LVO · DroidStar DMR for iOS

> DroidStar DMR for iOS is a free, open-source (GPL-3.0) digital amateur radio app for iPhone and iPad, built by Rohith Namboothiri (callsign VU3LVO, Bengaluru, India). Licensed hams use it to talk worldwide over DMR on BrandMeister (with ODTP), YSF, M17, P25, NXDN, D-STAR reflectors and AllStar/IAX without a radio. It is used by 10,000+ hams worldwide. It is distributed through Apple TestFlight. Request an invite at https://vu3lvo.com/testflight.
