There's been a house being built along my walk to the train station.  So each morning and evening I take a photo from the same spot.  Kinda the poor mans time-lapse.

I'd like to compile them into a movie when I'm finished.

Now since I'm not using a fixed point (bar standing in the same location each time, marked by a crack in the concrete) and freehanding the phone to take the photos - I'm expecting movement.

Short of manually taking each image and trying to align the size/angle etc can anyone thick of a tool that might automate some of it?

I'm not zooming so that shouldn't be an issue, but some will be not horizontal, the angle may change a bit as I can't guarantee I've pointed it at the same corner exactly.

I guess something that I can easily line up the horizon (vertically and horizontally) and then put in a consistent crop to try and get a similar viewport.
