SSTV+ is a Slow Scan Television audio encoder and decoder designed for amateur radio enthusiasts. Use your iPhone’s microphone to listen for SSTV audio signals. SSTV+ automatically detects the VIS mode and progressively reconstructs the image entirely on your device. You can also select a photo from your library, encode it as standard SSTV audio, play it through the device speaker, or export it as a WAV file. Key Features: • Receive and decode SSTV audio signals in real time • Automatically detect VIS modes • Encode photos as SSTV audio • Scale, fill, crop, and reposition images • Support Robot 36 and Robot 72 • Support Martin M1 and Martin M2 • Support Scottie S1 and Scottie S2 • Support PD 90, PD 120, and PD 180 • Keep a local history of received and transmitted images • Optionally retain original received audio • Export and share WAV audio files • Save decoded images to your Photos library Completely Offline: SSTV+ requires no account or sign-in and does not connect to any servers. Signal detection, image decoding, and audio generation are performed entirely on your device. The app contains no advertising, user tracking, analytics SDKs, or cloud synchronization. Your photos, audio, and history remain stored locally on your device. Nothing is uploaded to the developer or shared with third parties. All core features remain available without an internet connection. Permissions: • Microphone: Used only to receive and decode nearby SSTV audio signals • Photos: Used only when you choose a photo for encoding or save a decoded image SSTV+ only processes and plays audio. It does not directly transmit radio-frequency signals. When using the app with external radio equipment, please follow the amateur radio regulations applicable in your country or region.
