I know Apple makes it harder to do true hardware. I use SDR sharp and sdr console on pc. This is pretty close on iOS. A little temperamental at times with settings and network server config. But best out there on iOS I have found. Wish it had native air spyserver.

I was very apprehensive about buying this, based off the screenshots and the fact that it’s one of the only rtlsdr apps available. $10 is way too much for this. Maybe $2 would be ok but this is sub par. Sometimes it doesn’t connect, or will just decide to drop off and stop all audio and demodulation randomly. The waterfall is glitchy and doesn’t scroll. The interface is very bad. You can’t change modes without stopping the connection and changing it, then starting again, hoping that it will reconnect. You also cannot change the bandwidth of the current frequency. The ui is also glitched on the iPhone 8, the orange text that shows the status is down in the corner and only shows the first letter. As an only option I guess it works, but it really needs big improvements to be worth the $10.

I combined $25 sdr, Ham It Up, Youloop antenna with a raspberry pi and how I have a internet accessible shortwave radio.

This app does not work on IOS without a secondary device (computer) plugged into it. Not boldly stated and doesn’t look like a refund will be issued.

Bought the app and never can get it to work with my SDR server. Contacted dev for support. Tried another server software he recommended. Still wouldnt work. Tried connecting to several other online SDR servers, and none will connect with the app. Apple wont refund purchase. Save yourself the pain and dont buy.

This is the ONLY (iOS) RTL-SDR application in town. It’s get the job down, albeit crashes occasionally and could use some polish. I’d like to be about to pinch bandwidth. Needs a LOT of work. I sincerely hope they continue developing. Could be a great app. Not worth $10, I hate to say..

- bookmark of frequencies is too small (only allow to save 5 freq) - real-time saving - auto scanning

Looking forward to using this app as it matures. It worked right away with my Raspberry Pi RTL server. It even works OK over my VPN. Features that it definitely needs in future updates: 1) The upconverter frequency needs to allow a more exact calibration down to 1 Hz. 2) Same for the PPM value. At least 3 decimal points are needed for accuracy. 3) A slider would be helpful for fine tuning SSB and CW signals. Say +/-1000 Hz. Maybe along a vertical edge. Nice effort, well done. Keep up the good work. Much appreciated!

The BIG variable is network bandwidth. But at the lowest sampling rate it works good. Using a Raspberry Pi 3+ server. Up/Down tuning buttons would be nice with it changing the selected frequency digit for slow or fast tuning.
