### 1/5 — Where's the test?

*2024-08-31, version 4.1.0*

So fun that the interface doesn't show you where to do the vigilance test. Brilliant. User interface team, A+! Did you think to test it on uninitiated subjects and see how they interact with the program? hard to imagine that you did and didn't discover the importance of having clear buttons signalling where to find the test...

### 1/5 — Ne fonctionne pas IPAD

*2013-10-21, version 1.1*

Je viens de payer 3 dollars et pendant l'explication, l'apps se ferme toute seule. Aidez-moi svp.

### 2/5 — Crashes so frequently it's nearly unusable

*2015-08-28*

Sadly this app crashes so frequently that it's nearly unusable. To make matters worse, the crashes typically occur upon completion of the visual psycho-motor tests, losing the data collected during the test. While the idea of better understanding the effect of sleep patterns on performance is attractive, and the pedigree of the app's developers lend it credibility, the basic dysfunction of the app renders it unworkable and not worth the effort to undertake the tests repeatedly.

### 4/5 — Great idea, somewhat unstable

*2015-08-28*

It crashes sometimes during the test itself, sometimes during the data entry before the test. 
Other than that, great.

### 5/5 — Fixed crash issue (from developer)

*2015-11-01*

Hi brosnaro -
We addressed the issues with the app crashing.
Sorry about that.

### 5/5 — Great App!!

*2013-02-26, version 1.0*

As sleep researchers, we always look out for easier and reliable ways to measure vigilance across long periods of time. This App does it! This is a great tool and its simplicity is amazing. It can be compared to the traditional and classic Psychomotor Vigilance Test (PVT) widely used in sleep research but with portability and accessibility qualities that make this App more advantageous.

### 5/5 — Brought me to a higher level!

*2013-01-07, version 1.0*

I tought I could go to bed late and stay alert, but this app showed me that even a single late bedtime affects my reaction times for a few days. Thanks to this app, I'm now aware that going to bed earlier really improves my performances.

### 5/5 — Finally!

*2012-11-21, version 1.0*

We ve been searching for a tool to help our top performing clients achieve their full potential. sleep-2-Peak has brought our practice to a new level, helping people to measure themselves in a way to better understand what makes them achieve their peak states.

### 5/5 — great app

*2012-09-28, version 1.0*

Really easy to use. simple yet precise and useful.

the graphs are interesting to learn about your "best" sleep pattern not only to be ready for your day but to be at peak for your performance (physically and/or mentally)

### 5/5 — I've been looking for something like this

*2012-09-25*

As a marathon runner I've been looking for something that can give me better feedback on how I can organize my schedule around better exercise. Thanks guys for developing this app :)

### 5/5 — Nice app to stay a peak level!

*2012-09-14, version 1.0*

Quick and easy to use. I read on creators and they are well known in that research field. Cannot wait to have few weeks of data to analyze!
