Don't Buy! Works when you first install and the companion driver. Later prompts to buy, but navigation to refuse doesn't function, while purchasing works fine. Otherwise phone is locked up. Is this the secret to million + sales? I can write App to do this, could someone else? While app runs tuning has two modes. Those being, adjust bandwidth, and adjust frequency. Each mode works such is easy to use, but switching between modes only ever happens accidentally. I never figured out how to use.

Not sure why some reviewers are down on this app - I've used it a few years and it's amazing for taking SDR dongles on holidays or into the great outdoors. It's pretty inexpensive yet lets you use a USB dongle or a networked TCP source, has a draggable spectrum display, adjustable bandwidth, various signal types/modes, lets you record audio and can also scan for active signals. What's not to like? My guess is the negative comments are from people who know very little about SDR!

Great app, doesn't work well on the latest Android - disconnects at random. Worked flawlessly on my friend's older tablet. Please fix it! I love this app generally. EDIT: The problem may be the SDRPlay driver. Try this app, if it works, it's great! Update: got a response from the developer about turning off battery saving features. I'll try that. Thanks! Edited

Hello, battery saving features of some devices can prevent the driver app from running properly. I would suggest turning off the battery saving features of your device for the driver app and SDR Touch. You can find information on how to do this for your device online.

I had this application installed on my LG Android tablet for years, but I never fully learned it. In the beginning, I only used it with my Shark SDR-RTL as an FM radio, just for fun. After I rekindled my SW listening hobby, I decided to give it a try. I even bought the SpyVerter up converter. However, other things got in the way and I did not even test it. Now that I have a bit more of free time, I decided to explore SDR again.I tried several Windows SDR applications, each with its own pros and cons. After finding the best working settings for my SDR-RTL+SpyVerter setup, I decided to try again with SDR Touch. Boy! It was not only simpler than I though it would be. I tried it with the up converter, which was a breeze to setup and it worked very well. Looking around the configuration, I found the way to do direct sampling, which means that I do not need the up converter (less drain to the battery). Unfortunately, the upconverter does add a bit of gain as well as some needed filtering to my SDR-RTL dongle. I am still discovering this app, but I am very happy with it, so far.

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.
