No results

You can’t see the results even from the demo and it says they is no results collected, which seems to be the only point of the app.

Unbelievable...

The best and brightest, inspiring confidence, can't even build a basic app that shows results. it's like it was designed by alien artificial intelligence is to see how users respond to the frustration of taking a test and not being provided the results. maybe it's an intelligence test? Can you search through the menus and find your results? maybe somebody can, but I sure couldn't, nor could I find it in the various forms of documentation scattered across the Internet... it's like setting up an e-commerce store with no way to check out. brilliant

Asleep

PVT research study tool

I have a rare, chronic sleep disorder. Myself and the other 200+ members of my support groups are looking for an app we can use to get objective feedback on alertness. I realize this is not what this app was intended for. But I wanted you to know if you ever decide to make a commercial version of your app, you definitely have a market among the Sleep disorder community.
