Uhm. Don't know what to say here. I have created over 20 different apps across four different platforms with gross sales approaching $4 Million and over 12 million total users. Yes, you can buy an LX100 4K camera for $800 or even an Xperia Z2 or LG G3 for $500 if you don't mind heavy compression and footage that cannot be graded in a studio or printed to film. Vizzywig 4K is a stills workflow that future proofs your footage. It's not hard to stabilize, slow down with Twixtor or add motion blur in After Effects if you start with pristine, raw still frames with no motion blur or heavy H.264 motion compression baked in.
The primary reason Vizzywig 4K is compelling is because there really is NO OTHER WAY to shoot, edit and upload to YouTube 4K from a phone. Vizzywig is a full-blown 4K multi-camera studio. That's right, you can simultaneously record and live switch from up to 16 iPhone 5S's and live switch in real-time, relevant 4K still frames are transferred from each remote camera to the master device and you can edit, add transitions, background music, titles, lower thirds and scrolling credits (all 4K) and upload to YouTube in minutes plus archive the entire still image sequence for future codecs.
Shutter speed issues are a problem on iOS 7. All of our demo videos were shot with a very high shutter speed. The only real solution to that on a fixed aperture camera is ND filtration. Moondog Labs (who makes the Anamorphic Lens) is building us a custom filter mount so we can add ND. On iOS 8, we can use a 1/48th shutter but ND will still be required because you cannot dial ISO down enough in daylight.

Because there is a lot more to a complete 4K workflow than burst photos. There are only two apps on Android and iOS combined that are capable of capturing 24 full-sensor-resolution photos per second. Both are made by i4software.
