Awesome app for SSTV

I have tried a few other pieces of SSTV software, and none have been this easy to set up. The app is super easy to use and has great reception and options.

Absolutely 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 youโ€™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!

Inconvenience in use

First, I miss the mode of automatic detection of the message encoding mode during Rx. Second, during tx at the beginning of the program, there is no code sound indicating the transmission mode. Thirdly, there are not enough modes for tx. Fourth, outdated interface. Fifth, when I want to take a photo using the camera in the application, it crashes. If all these points are fixed, it will be the best application on the market and sales will bring a lot of money

Useless

I guess the last โ€œwhatโ€™s newโ€ being from nine years ago should have been a hint. iPhone 15 pro and this app just crashes any time I try to do anything at all with it.
