applications – Photo app to stitch multiple photos together?

I’ve found it to be extremely convenient to both snap and crop photo with my phone before uploading it somewhere without the need to copy it over to my computer for editing. The default photo editor on my Android device does this just fine. But it has no feature for stitching a collection of photos together.

Is there a free or other (paid/no ads) photo editor for Android that will allow me to quickly stitch multiple photos together either horizontally or vertically?
