CloudApp is ubiquitous and although we'd encountered one another before, it took AppSumo to formally introduce us. To explain, I'd be watching a training comprising a high-quality screen share, complete with cut out circle where the author would be nattering away, nestled neatly in the corner of the screen, and I'd think, yeah this look legit, good job ma Man/Lady/M'Lady etc. Then AppSumo puts CloudApp up - ah, that's their secret! This is a brilliant deal, it makes sharing, annotating, and teaching simple and easy. Want to get notified via email when someone opens your share - you don't even have to set it up - CloudApp has thought of these important details for you. Hot keys are built in and prompted so initiating your shares soon becomes second nature. Further, there's a good deal of customisation to video recording which makes this a versatile teaching aid. Thanks to CloudApp and AppSumo for providing so much value with this deal :-)
