False Advertising

Downloading the app is free but if you want to use any functionality you have to buy their subscription, can’t even upload files.

Catfished!

I bought this app thinking I could make the music I stream from my Spotify louder! What a misleading description and now I’m stuck with this useless app that can only make downloaded music files louder! Not what I wanted or needed! If you want an app to boost the sound of your pandora/spotify playlists run away from this!

Oh my god I want my money back

You see, I have an app on my tablet that allows me to boost volume for watching YouTube… for this I have to import videos and I can’t use it with YouTube, give me my money back NOW

What I think

This app is okay I think that it would be better if you can import all songs at once instead having us only to import one song one at a time it also would be great if we can boost multiple tracks all at once another great option that would be great is if we can play all songs at once .

Why Is The App Free If NOTHING IS FREE

Why would you list this app as free on the App Store and then when it’s opened you can’t do anything for free? So dumb, you might as well just list this as an app you need to buy.
