What's New in SimpleSSTV

1.3.2

September 8, 2026

• Improved Simplified Chinese throughout the app, including purchase and restore messages, audio-device settings, radio-control status, permission prompts, and accessibility labels. • Stop now cancels a pending encode, and leaving the Encode tab stops transmission. • Restarting playback no longer lets an old audio callback end the new transmission early.

Truly Simple

Simple review for a simple app
Fred BehrendFred Behrend

Very Good, no ads

Very good, but the live function doesn’t work correctly, it sends the first picture, but only the first, then no images are sent anymore. And maybe with the decoding maybe add a live preview while it’s getting decoded with the microphone.

Ham gone cold turkey

I am a former ham radio operator. I can use this on MURS on my property as a webcam that doesn’t need the internet! This is so cool!
