Sinply THE BEST video editing app for iPhones – Filmr - Pro Video Editor Review

It can crashes sometimes if you add too much elements such as text or effects or if you're editing aspects like hue, offtone, sharpness, grain or vignette but if the app crash and shut down it automatically save your project right on the point before it shut down so you don't lose your work. It's really the best for mobile I've ever used and the paid version really worth it tho!
