It works. You can't get any better than that. I've paid way more for SDR apps that did a fraction of what this app can do. Simple and easy to use UI. It would be cool to see the driver embedded in the app, instead of another app download, but that's really the only 'difficult' part of this app. Highly recommend.
For €0.79 this app is 10x less expensive than sdr touch and for that reason I gave it four stars. There are some improvements needed such as setting squelch and bandwidth could be easier, recording audio as well as the entire band, there is a high-pitched tone when using wide band fm, a way that makes it easier to fine tune and stability improvements. This app works pretty well on my device (OnePlus 2) but it does crash every now and then (when changing between portrait and landscape for example). I think this app is great for the price and does pretty much everything I need but I would like to see these improvements.
Squelch is non-existent in this app. The developer claims it exists but it is impossible to set up. No matter how I adjust the gain I always hear the RF noise in between the transmissions. This app will make me deaf. The only way to eliminate the noise is to manually move the dB slider up and down which very impractical and annoying. Every free PC SDR software has perfectly working squelch. Why this one doesn't? Could be a great app but luck of squelch makes it unusable. I would expect this to be fixed.
App works well once it's running. Has all the features I need. However on my one plus 3t the app crashes every time I change a setting, pause playback or switch apps.
Will not connect to rtl-sdr. shows errors, but they don't stay on screen long enough to read. Useless
This software is worth for purchase. I would suggest to enhance it by wide band analyzer. Then it will be useful also at DVB-T antenna and equipment tuning. I use this app on Samsung Galaxy S3 Mini which has flashed Android 5.1.1. CyanogenMod. Simple OTG cable is not enough, I bought Rolline OTG cable with extra power input (third USB connector on the cable).
