I want to manage my receipts. I tried several apps made for that purpose, but results were not so good as I expected (eg. no way to share, weird storage format). So now my idea is that I just want to have a collection of photos (of my receipts) together with my some metadata (always the same set). Therefore I need an application that:

1. Is able to take a photo (preferably using external app).
2. Allow me to add some metadata according to predefined template (date of purchase, warranty length, value, etc.). Preferably while still displaying image on screen.
3. Save to predefined folder.

I don't need any reporting and fancy features. Some photo preprocessing of image receipt would be a nice addition (eg. take receipt out of background, find out product name and value, purchase date), but it is certainly not necessary. Also editing of metadata is not a must - as long as it can be done in any other application.
