Best free video editing app for Iphone?

Hi i'm looking for a app that i can edit videos on. On it i must be able to connect 2 different videos together and edit them. It would be cool to add effects or add sound to it if possible.

EASY 10 POINTS!

Splice has a free version
and it's a good video editing app

Well, Iphone editing isn't very good just yet. But the best app for that (for now) that i know of is Imovie. It let's u record sound, or add from you music library. And it has inbuilt sound effects you can use. And you can edit videos.
It's made by Apple and costs 5 dollars i believe.

IMovie, I know that it is 5.99 but it's a really great app. There's also splice, it's a video editing app. I also use splice. You can string videos together, add sound, add music, add recordings, add titles, ect. The app is called splice.

This stuff is better done on a computer, trying to do this stuff on a little phone screen is not the best way.
