Best scanning app Ive tried

... And Ive tried many. It is good at recognising edges and it actually enhances the quality of scans ( unlike many that in such attempt make them completely illegible) . It works for things like old receipts or documents printed with dot matrix printers - which are poor quality to start with. Offers a number of formats to save the scan in, and leaves no watermarks. Summing up, nobody will realise you scanned the doc using your phone.
