User reviews

Works great

rtl_tcp running in a Linux (Ubuntu) VM on a cheap $249 (2024 dollar) PC. Works great on my iPhone at home, or from anywhere on earth with a VPN connection home.

Response from developer

Thanks for the review. Glad you are enjoying the app!

A basic, stable tcp set client

This is a basic “radio” app for listening to AM, nb FM (like NOAA weather radio), and wb FM (FM broadcast). Does not do SSB. Minus one star for not supporting stereo FM. Hopefully in a future version!

Response from developer

Thanks for the review! More modes are on the roadmap.

this app is incredible

deserves every star. thank you for developing this on iOS, there are no alternatives.

Cool app

Great app if you have list of known frequency’s you want to monitor
It’s one of those nice apps where it’s simple / obvious to use with the exception of importing your CSV. It would be helpful if the pop up telling you there’s nothing to import also tells you that you can also use the file share feature to import 😀

Needs SSB modulation

Great app for storing interesting frequencies. There is no SWLing logging app for iOS and this is the closest I could find. A few features that would make this a killer app: -

1. Addition of USB and LSB modulation would be useful for storing VLF and aeronautical frequencies such as Volmets.
2. Date and time that frequencies were heard.
3. Integration with online station ID databases.
4. A waterfall would be amazing!
