This used to be a great app for photo correction. I had given it a glowing five star review. While technically "free", so many paywalls have been added that using the word "free" is purely marketing. If you want to waste your time downloading the app and opening it, go on ahead. I can't stop you. If you want to correct your photos for free, you'll need to look elsewhere. There are countless alternatives out there that will get the job done for you. Stay away.
