This is an excellent app, I’m only rating it 4 stars because I have some requests and one thing I have an issue with.1: I enjoy the ability to play audio files as music, and I would like that feature to be leaned into more. For example, the ability to create playlists. In order to play several songs in a row without playing every audio file in the app, I have to manually combine the songs into one, limiting the amount I can have playing at once and making it a bit awkward to set up.2: add a one-time payment to get rid of all ads, like others have suggested. Not much else to say about this one, it speaks for itself.3: the ads are USUALLY unobtrusive. Unfortunately, an issue I only experienced on my older iPhone was the fact that, when extracting audio, a nearly fullscreen ad will pop up, putting a button at the top of the screen that you need to press to get rid of it. As the button to view the audio is usually at the bottom of the screen, this leads to accidentally clicking on the ad a lot of the time if you’re not used to it. If this is something that only happens on older phones, I don’t have as much of an issue with it, but if it’s some kind of random chance that could theoretically be applied to any version, I hope it’s removed.I would give this app 4 1/2 stars if I could, but I unfortunately can only rate it 4, so know this review is mostly just small things and a few recommendations to make the app better. I really enjoy this app and hope it continues to improve.
