iTunes offers Vizzywig for iPhone and iPad for free. That's a $20 drop and the first time we've seen this video editing app offered for free.
the reviews are a hit or a complete miss. I have an older 6plus so it will do fine with this version, go to the upgraded version for newer iPhones.
This is the 2014 version it's now end-of-life software the 2017 version is 99.00 and supports newer iPhones and higher resolutions.
If it matters to you, it's not the newest version of this app. The 2017 version is going to set you back $99.00. Not sure what the difference is between the two versions but I like free a whole lot better!
