I have used this app for over two years. While on the road I accumulate receipts, financial, legal, and medical documents. I use this app to get an image of each document and save as a pdf (in my case) and save directly to my cloud service — files are then accessible to all my devices. When I get home I no longer have a pile of scanning to do. Also, for any single document of a few pages, this is quicker than using my scanner and notebook. The quality is excellent since my iPhone 6 Plus has a great camera. If you want or need a portable scanner and have a good device like an iPhone then this app can help you make efficient use of your time.
Also, I contacted customer service for the first time (I reluctantly read manuals) and they got back to me the next day with a solution that worked — they are civilized too!
