Video Volume Amp, Bass Booster

simple, effective. i use it to improve amplitude on some of my binaural recordings of very quiet things. does exactly what i need with a minor caveat - Dolby Vision is lost to HDR10 after conversion- not sure this matters or if it’s mangled, all looks and sounds good though could do with a progress bar for importing longer videos because it doesn’t look like anything happened til your video appears one of the only apps of its kind with a one-time lifetime purchase option

Volume doesn’t go up at all, I would like a refund

.

Don’t waste your time this app absolutely does nothing it’s a waste of time my volume button on iPhone 5 has more options and does more than this .

Does work …

Kind of hard to know if I’d like to purchase this app if I can’t sample any of the features except for boosting volume from my videos. I can’t live boost anything at all nor try any of the noise cancellation features etc only able to boost 30 seconds of already recorded videos

Waste of money it’s a joke. I want my money back!!!!

I was looking for an app to increase the audio in some videos when I installed this app. It is easy to use and works great. I wish it kept the original file name structure and was able to open files from other locations instead of just from the photo album but it does allow export to other locations. Other than that, it works great and the lifetime purchase price was much more reasonable than other similar apps in the App Store.

Title says enough, the app might as well cost money

It's not free version even by limitations You might buy it Actually we can't register it in iran 🇮🇷 and admin never attention to asked them for a free version This app might be great if has a free ver for whom can't buy it.
