User Reviews

PulseModem A is praised for being free and easy to use, letting you TX via RF with an iPhone and any radio and connect to APRS-IS. Reviewers highlight a clean interface and the ability to use RF or Internet for APRS. However, recurring issues include RF decode/receive problems and transmissions not appearing in the app, setup/connectivity glitches (swapped host/password fields), missing essential features (auto beacon, messaging), and occasional crashes. Overall it’s a solid free entry point with room for feature improvements and reliability enhancements.

Pros

Free app
TX via RF with iPhone and any radio; no need for an expensive TNC
Works with APRS-IS / TCP/IP connectivity
Clean/simple, easy-to-use interface

Cons

RF receive/decode not working as expected; own transmissions not visible in the app
Connection/setup issues due to swapped/mislabelled host/password fields and difficulty connecting with valid callsign
Missing essential features like auto-beacon and messaging interface (no periodic beacon, no messaging)
Stability issues including crashes and inability to open the app on some devices

While it is not the equal of a $700+ Kenwood HT it is a fun way to experience APRS either through an inexpensive plain vanilla HT or directly into the APRS Internet Network.
