I've previously used Hello Sign to sign documents on my iPhone, but Genius Scan (another product from these devs) is the best mobile scanning app that I've found, so I'm definitely interested to start using this app.
It's currently $0.99 in promo, as it just launched. I'm not sure how much they'll charge for it after - their Genius Scan+ app costs $6.99, so maybe around that.
i'm not sure how to add a link to the iTunes store to download it, Product Hunt seemed to have moved/removed that functionality. But the download link is: https://itunes.apple.com/us/app/...
