1. 4/5(Null)

   Some people are mentioning that the program superimposes the word NULL on your image and there’s no way to get rid of it. Not true. If you press the transmit button, you’ll see the option to upload a photo from your Photos, or use your camera. If you press upload photo from photos library, AND you then select your photo, THEN you will see a list of five options. Pick option three, “set text.” You have to put something in here to get rid of the word, NULL that shows up in your transmitted picture. Leaving it blank is not an option. At least it gives you the opportunity to make the superimposed text Tiny or Large. I picked Tiny and just put in my callsign. You might be able to get away with just dropping a period in the cell and making it tiny. So, you can either choose to not put your call sign in your picture and let this program superimpose your call sign where it’s going to and build your photo around it, or you can create your call sign in your picture and then just have this stupid functionality put your call sign again, in super small letters and just say “whatever”. The functionality to get rid of NULL is there, it’s just buried.

2. 5/5Only and best iOS SSTV app!

   I really like this app, and I am happy this developer really made sure everything works. Everything works very intuitively, with very minimal UI that is easy to learn and not too many colors and buttons to overload you. Some folks complained about how you can't save the image and that it sometimes disappears, but simply turning on "Save to Photos" works. I have also never encountered anything randomly disappearing. Also, many others complained about the app crashing upon startup. But no. I am on an 8th generation iPad, running iOS 17.0.3, and I have not experienced any crashes. Some others have complained about "NULL" appearing on their transmitted images, but that is a feature. It can be easily disabled by backspacing the text when in the image selection and editing menu. Finally, some have complained about some transmission methods not being able to transmit. They are completely correct about this. But they are ones I have never heard of, and ones I will probably never use. Anyways thanks for reading this review.

3. 5/5Absolutely awesome

   CQ SSTV by Black Cat is one of the best SSTV apps available for amateur radio operators. The interface is clean, simple, and reliable, making it easy to send and receive SSTV images whether you’re a beginner or a longtime ham. The app performs extremely well with clear decodes, stable operation, and excellent compatibility with popular SSTV modes. What really stands out is how fast and responsive the app feels during live operation. The controls are straightforward, audio handling is solid, and it works great for portable operations, field events, and casual SSTV nets. The developer has clearly put a lot of thought into both usability and ham radio functionality. If you enjoy SSTV, especially events like SSTV Sundays or portable operations, CQ SSTV is absolutely worth downloading. Huge thanks to Black Cat for creating such a dependable and enjoyable app for the amateur radio community!

4. 4/5Great for on the go SSTV

   This app is great for receiving and transmitting SSTV Images! Receiving is easy. Just set your mode (or set to auto detect) and hold your phone up to your radio’s speaker when theres a SSTV signal. I already managed to get a few images from the international space station. I wish that I was able to transmit on the PD modes, the rest work great though. I’m able to pick a picture on from my phone, add some text and then hold my phone up to my radios mic. (PS, don’t forget to check your radios timeout function if you’re using a mode that takes longer to transmit)

5. 4/5It does work, but…

   So the app will do what it says; it will decode sstv images from the audio streams that it hears. You can save your images in the app, but you’ll need to screenshot them if you want them in your photos. And it only hears via the microphone; it cannot use a saved audio file for input. It only decodes live over the mic. Sad that you have to buy it to find out what the limitations are.
