Evernote Scannable 4+

At last, a scanning app that works! I've tried so many of these scanning apps and ended up frustrated and abandoning them all due to their shortcomings. Scannable finally puts that right - and unlike most of the others, it's free. The page boundary detection is pretty flawless provided there's contrast with the background, and on the iPhone 7 it's insanely fast. I've generally found though that you get a better, cleaner PDF if you switch to manual for starting the scan, and the cleaner scan gives the OCR better text to work with.

While it will do a good job of receipts etc, where it really shines is full A4, where you'll end up with a straight document with crisp whites, sharp text and virtually no greys around the crease.

Evernote have removed 2 speed features from this app.
1 - Previously you could quickly specify in-app, for each scan, which Evernote Notebook you wanted scan to go into. E.g. Business Receipts or Tax Letters. Didn’t look very elegant but it was quick. Rather than try and make it look better they just removed it. So to categorise your scans you now are now forced to scan the doc THEN go into Evernote app (which still takes too long to load especially if you are out of mobile data/wifi range), load and re-categorise your new scan. More time, more button presses.
2 - They have also removed option to scan and quickly share to other apps from Scannable. You have to do that from Evernote. So it’ll now take you much longer if you want to scan something and WhatsApp it/email it/save it to cloud drive etc.
Cheers guys. Great job.

I don't often write reviews and it's normally to warn people away from poor performing Apps. Thankfully this app is AMAZING. I am a self employed consultant and travel around the world with a need to scan all sorts of documents for both business and invoicing. I had nearly given up trying to find an app that works, all the other apps I have tried have been over complicated and don't perform well. I was then recommended Scannable by a friend. This app is great. Every element works well and is simple to use in every way. This has easily given one day of my life back every month, no longer am I tied to a scanner sorting a two week business trip.

A great app free of charge, please download it you will not be disappointed.
