I give the concept a 5 star, but the app falls well short.
It takes pictures just fine. However, too many bugs that prevented me from using the app beyond just the capabilities of the iPhone app.
First of all, there are no in app instructions beyond initial setup, which there werent enough instructions supplied in initial setup, as well.
I love the feature of splitting my focal point and exposure point; however, the double-tap function is too sensitive/restrictive. It takes me 5 or 6 double-taps to make it split. Quite annoying, and too slow for when you need a quick shot. If it worked the first time you tried, it would be great. (Double-tap tried on a phone with no protector, and I had my 12 year old try with his smaller fingers, as well. Issue is not the user.)
They have a creative idea with the case for lens modification; however, without the case and lens Attachment, I hit the button for choosing a lens and there is no way to unselect the attachment option. I am stuck with T/W/M, as it does not revert to the phones standard setting.
The controls (swiping) to open exposure, focus, temperature are not intuitive and are clunky.
Finally, the first five reviews appear to be company plants, as they all rate the app at 5 stars and combined cover most of their selling points. The most suspicious is the review saying that they have great customer service without explaining what issue was resolved for them.
I think the app has great potential, and I am excited to use it and the control that it will provide, if these issues are resolved.
I will watch to see what they do to fix these issues and will revise my review accordingly.
