## Most critical reviews (4 lowest-rated)

### 1/5 — No results

*2024-09-05, version 1.5.0*

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.

### 1/5 — Unbelievable...

*2024-08-31, version 1.5.0*

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

### 3/5 — Fell

*2023-01-05*

Asleep

### 5/5 — PVT research study tool

*2020-11-22*

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.
