I tried this out after reading a few reviews. It's true that it's feature-packed and very professional, but the huge problem for me was that I couldn't find or access my recordings. The free version won't allow you to transfer your files to Google Drive and they are totally unfindable on your device. It's sad really, sorry since it's a great recorder, but that's no use to me if I can't find or use my recordings.

What a great app for recording voice audio with high audio quality. Unfortunately, sharing the audio files to my Google drive was impossible. Even after following all of the instructions and creating a new file path, uploads would still fail. If the sharing process gets simplified this would easily be a 5 star app.

The app offers advanced feature choice and quality recordings. But has serious bugs and deficiencies. Its "Device List" for my Android 10 phone shows same device names several times with no hints what they mean or how different. UI is not Material Design compliant. Obsolete codecs, like SPEEX for compact voice recording superseded by OPUS years ago. With each recorded audio file, the app also creates some extra files in a hidden folder that add up quickly. Many app options unfamiliar to novices, and some are confusingly repeated in different Settings sections. Yet support is non-existent, replaced with rude forum mod & admin conduct. No answers to emails and forum posts with Recorder suggestions or questions. Users asking for Recorder Manual and answers to questions are banned from the forum. All this violates Google Play ToS, as defective app content and no user help is offered despite advertised in the product listing. No intent shown to improve product or support, while Recorder is locked after 5 days trial asking to purchase.
