Ratings and Reviews

Seems cool so far

Amazing ... but

just downloaded it. gotta mess with it a little bit, but its pretty amazing

Great potential!


It might work great on newer phones, but it crashes when I try to add video on iPhone 5s. I recorded a live video to play around and it's just perfect. Audio is everything for film and the moment I can load a video I'll give this it 5 stars. I know these devs from their other software and they don't mess around.

Your watermark

STL After Dark

It's unfortunate that I can't find a "remove watermark" purchase ... so your otherwise 5 star app gets a 3 and no money.
