App doesn't work since update, it wasn't exactly "great" before, but since updating, it doesn't decode ANYTHING 🤷old version was deeply flawed, but better than new version 🧐 SSTV Decoders are no good unless there's a WORKING Auto mode, we never know what mode is being sent, by the time you go thru them all, the message is over 🤦

Works brilliantly! Decodes almost everything you'd ever care about for SSTV. I use it to verify what I'm sending really is what is supposed to be. Turns out, it always is.

Hey Ahmet, this app works really well at decoding, and that's without using a HAM radio and just playing back SSTV audio from YouTube. One note, and this doesn't affect the rating: it seems like Scottie DX peaks out the microphone and causes the app to switch to RAW for second intervals, which causes cyan-line artifacting that prevents images in that format from saving. Not your fault though, just a side effect of my mic being just OK. Everything else works great though!

It wasn't designed to do phone calls. Amazing how the decoder can automatically select format. Creates interesting effects when the encoder is played through an amplifier. Would like to try this in a large reverberation sized room. Working best when at lower volume not loud enough to bounce off of walls. Scottie DX is actually the only mode that doesn't smear my profile picture. I've got this encoder and decoder set on 3 of my devices. I've sent my profile picture to myself through every single mode this pair can do. Looking forward to the day I can actually use them with a radio or even home phone.

I just lost a nearly perfectly decoded image because I accidentally hit the delete button instead of the save button.Needs a confirm dialog. Catastrophic data loss. Also, "Auto mode" isn't clear... tapping menu button seems to do nothing. Is it active? Show a checkbox? Could be improved a good bit, but not bad for a free app.

I love this app, but I've had a slight problem this last time I've installed it... For some reason the save button is greyed out, and the share button doesn't seem to do anything. Is there any reason this would be happening that I'm just missing? I had to save my last image via screenshot, which isn't ideal, so I'd rather be able to use the default save feature :) I'm on Android 10 on a Nokia 7.1 Thanks for the great app!

We've been using this app for some times now to decode the International Space Station SSTV events. It's been really fun, very easy to use. Unfortunately the space station has had an issue with their radio for the last year so we've not been able to get any new images from there. However, there is a YouTube channel called 'Slow Scan TV' that's got a couple of thousand of SSTV to decode, and itched that itch. Brilliant app, and never fails to impress adult and children alike with the ISS.
