Best free photo to PDF app out Ive found

I need it for receipts mostly. Genius Scan lets me name, rotate, and switch color/black-n-white before emailing. I just noticed I can not only do multi-page docs, but I can move pages between docs. It even supports direct wifi sharing to another device via the other devices web browser. This is everything I need and more than I expected. Im considering buying the pro version just to support the developer. The free version is awesome and that should be rewarded.
