Eine looking for an app for video editing explanation follows😭😭?

So it's complicated…

I'm looking for an app (for iphone) in which you put together 2 or more videos but just do not put together this normal but something where you can, for example. 2videos has and you want to play each one of the two for 0.5 seconds and then follows the other…

short:

Video1 starts at 0 sec and goes to 0.5 then follows Video2 which starts at 0.5 sec and goes to 1.0 sec and then always alternately so on

to the fortnite TikToker that may be on the way here:

I would like to post a video where I have 2+ skins and then they play alternately the good transitions and I have a skin change 😭😭😭 Please help me

You will not find something for Iphone… I can cut it up for you Pc

No problem with iMovie.
