The ease of use that allows us so quickly get up & running without having any knowledge about creating mobile applications is amazing! It's also such an easy platform for our internal users as well which makes it even more appealing than other platforms we've used previously (both proprietary).
I don't like how you can only have one app being developed at once - if there are multiple people working off different branches or features they will all be waiting until someone gets their branch approved before moving forward themselves but this could just come down from Fat Finger itself rather then me complaining here though :) Otherwise great product- very intuitive interface; excellent customer support team who helped develop my initial version/ proofing process when setting out what functionality was required etc.;.
