Matthias Hochgatterer, in a blog post detailing the invoice scanning feature he brought to Finances for iOS with an update released today:
I’ve just recently worked on invoice scanning for Finances. It lets you scan invoices on iPhone or iPad and add them as a PDF document to transactions. In this post I will show you how I’ve implemented that feature using the frameworks available on iOS.
Let’s start by looking at the final result. You can see the invoice scanning in the Finances trailer. The user interface looks very similar to the document scanning UI in Apple’s Notes app on iOS 11. That’s not a coincident. I’ve reimplemented the exact same user interface, because most iOS users are already familiar with it. Also I found it an interesting challenge to implement it myself.
I’ve been considering Finances (which is available both on Mac and iOS and is on sale for both platforms today) as a replacement for the system I built in Numbers last year, which isn’t scaling anymore (my accountant now wants me to upload PDF receipts to a Trello board, and traditional spreadsheets do not support inline file attachments). I’m intrigued by the cross-platform nature of Finances, its double-entry bookkeeping system, and this new Notes-like scanning mode built using Vision technologies in iOS 11. I haven’t seen other apps publicly advertise scanning functionalities built using Vision and the implementation in Finances looks extremely well done.
I will be playing around with Finances over the weekend (I know; usually, this isn’t what I do with my weekends but I also need to keep my accountant happy). You can take a look at Finances’ new trailer below.
