Nice concept but poor execution – EyeQue PVT Review

So I like the idea of a simple device which allows me to check my eye's prescription, however my experience so far has been far from ideal. The night I got the device I tried 3 times, and although I completed the test, it never gave me results - though they seemed to briefly appear. Today I've updated the app and now it won't launch on my iPhone 6 - it claims it's an incompatible device. Eyeque really need to sort out their software and the back end servers which are used to do some of the calculations.
