"Works for about 2 mins, there is a timer on the screen, after that, it says your trial has expired and you have to buy the pro version.... Hard pass... Not wasting my time on or money on a shady business like that. Thanks for nothing."

"Been using this app for years now. By far the best SDR I`ve found for Android. It is the only RTL-SDR app I`ve found in the Google Play Store that is actively maintained with a multi-year track record. There are occasional glitches, but I`ve never found anything that prevents the use of the app. I`m happy to pay for such an app."

"I have had a great time with rtl-sdr radio and I believe that if someone was going to be in a career that uses radio this would be an excellent radio hobby."

"This is one of the only applications I know all of its sort and it works very well and I will give it a 4 out of 5 stars but it does require supported Hardware such as heck rf4 rtl-sdr and it will require some technical knowledge"

"Been using this app on my Samsung Galaxy S21 Ultra, works great with my SDR dongle. Steve Fury posted that you are unable to switch channels quickly, this is not the case. There is an JUMP button that allows you to manually enter the frequency you want to go to. Going to pick up a tablet as I would like to see this on a larger screen."

"I love this truly portable SDR solution. Please purchase the ``Pro`` key to help out the developer. I use a NooElec dongle with my AT&T Samsung View 18.4, and it works GREAT!"

"My Galaxy S8+ has it working great. I have yet to try it on my tablet. But on the phone, it works great. Obviously the better the antenna, the more you hear and it loves my scanner antenna. Now to experiment with frequencies and what I can hear and to find a good portable antenna for it. Great app!"

"It freaking works, every time with any of my SDR dongles on any of my droids, regardless of size make or version. Not a huge learning curve, they haven`t pulled my key or tried to charge me again for it or require a limit on the number of devices I`ve put it on. For me it`s a good place to start prior to using one that runs on a PC. Thanks for letting it be enjoyable !"

"Full featured, powerful app! I was surprised that this app actually had the Q Branch Direct Sampling setting to tune in HF frequencies using the RTL-SDR V3 dongle. I thought I would probably have to use Windows software for this. It works great with this dongle and my phone. Can`t wait to try on the Samsung Galaxy Tab next."

"Great App, I would like to mesure the low EMF spectrum, starting from 20 hz. Is it possible with this App? I know I would need to use another Dongle as I use the RTL-SDR but its range does not do that low. Can the community advise if possible and what dongle do I need to get? Thanks!!!!"

"Look it`s a fairy good app ..I don`t mind it at all I think though there needs to be capability for TCP connection to the SDR device say I have the device connected to a Raspberry Pi or even a Windows machine and I want to simply control the device from my phone using the TCP spyserver this would be an excellent feature and would be muchly appreciated .."
