Where can I find an iPhone app like this?

I have an assignment where I have to take some photographs for one of my classes at school with my iPhone. I would like for them to sort of connect, but the details around this is not important. My question is if there's an app where I can first take a photo, and then see a semi-transparent version of that on my screen photo while I take another? So that I can align details and such so that they match in that way.

Using a tripod sadly won't do.

You can use burst photos on iphones now to take 10 quick photos

I don't know but may u find thing like that here
getjar.com

I guess something like PhotoSynth maybe able to help
