No rig handy? You can still explore.

SSTV-AF will decode from the phone's microphone, so you can hold it to a speaker playing SSTV and watch a picture come in before you wire up CAT control. See the FAQ for supported radios and cabling.

Free on GitHub — sideload the APK or build from source. Either way you get the whole app.
