Not good. – Voice Tuner - Vocal Changer Review

First off, the app asks you to buy pro edition for $20, which if you ask me (even though I haven't bought it) does not seem worth it. It simply removes ads and gives you access to built in tracks and editing. For another thing, ads pop up about every 2 minutes, which you have to pay to get rid of. Finally, all the tuning really does is make your voice either really high or low, with very minimal regard for notes/keys. I definitely do not recommend this app. (This is intended for suggestion to the app and is not meant to be taken offensively.)
