We loved using Rdio Scanner for our scanner traffic, but ThinLine takes it to a higher level! ThinLine fixes all the bugs and issues with Rdio Scanner and adds on that, while utilizing a nice clean interface. The developer has been very responsive to bugs and problems and has gone above and beyond to correct them. Our listeners love the app, they love being able to choose the channels they want to listen to across multiple counties.Definitely get the ad-free subscription. It’s less than $1/month and helps support the developers while 100% improving the experience.
MUST HAVE!

I am a first responder, and this app helps out tremendously! HIGHLY RECOMMEND! The creators are always keeping up with updates and making sure everything is working properly ! There are no delays and everything is real time , and can playback radio traffic and everything. Customer service gets back to you almost immediately if you have any issues or need help with something!
Useful for First Responders

This app has been an incredibly useful tool in my role as an on call investigator, not only does it provide me with a nice “heads up” when something is going on within my jurisdiction, it has the ability to replay, and to alert to specific key words that might be relevant to a particular role within first response. Great app developed by great people. Can’t wait to see how it continues to evolve.
Must have app!

I have been using this app since it all began. It has grown into an awesome app and the coverage area is awesome. Great way to hear comms off duty and great for avid listeners of scanners for public safety. Instant access to live incidents.
