User reviews

Great App even better server!

This is a great mobile interface to both Rdio Scanner and ThinLine Radio scanner servers. The engineer behind it is very responsive to feedback, feature requests and bug fixes. They’re also in the first responder community so they understand the primary use cases extremely well. The server software has been released in beta since late December 2025 and has come a long way with tons of value add features and functionality!

Only criticism is the sheer amounts of ads you get if you’re not subscribed to the app for $2 /mo which is WELL worth it to support maintenance and upgrades to the server and client apps.

Car Play

Excellent app !! Any CarPlay controls in the future ??

Has a lot of potential

The app is a more modern take on Rdio Scanner and was going to be what I suggest everyone use, but the newly added full screen ads that can’t be dismissed quickly why trying to get to sometimes time sensitive calls is a dealbreaker. Ideally there would be no ads or a low cost one time payment to remove them, but if they must be there, full screen is a complete non-starter.

Response from developer

Go to app settings, scroll down to subscription to remove ads. It’s a low monthly payment that supports the continued development.

Terrible

Terrible product that doesn’t work.

Response from developer

It does actually, reach out to support for once if you have issues before writing a review that is false.

Great App for Local Updates
