Latry is an application that lets amateur radio operators connect to the SvxReflector network from mobile platforms. The app provides tap-to-talk voice communication, allowing you to join talkgroups and chat with other users over the internet. After entering your server host, port, callsign, authentication key, and desired talkgroup, Latry establishes a secure connection and handles audio streaming using the Opus codec. Latry supports displaying names for other users on the network when available. Settings are saved locally, so your server details are ready the next time you connect. This project is provided for hobbyist use and is not affiliated with the official SvxLink project. Use it responsibly and comply with your local amateur radio regulations.

Verdict
The clearest difference is price: Latry at Free against SDR's $49.99. Latry also leads on update cadence (daily vs every 2 weeks) and review sentiment (100% vs 78%). SDR's advantage is ratings volume (70 vs 1). On rating, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Latry is free to download; SDR costs $49.99 up front. Neither carries in-app purchases, so what you see is what you pay.
SDR holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: SDR has 70 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 78% of SDR's written reviews are positive against 100% of Latry's, so the app with the better star average is not the one people write more warmly about.
SDR ships an update every 2 weeks, Latry daily. The most recent releases landed on November 3, 2026 and October 24, 2026 respectively.
