### 4/5 — Good tool

*2025-11-28*

Administers PVT appropriately and with an easy format. It has place to fill in first and last name when you do a test, but it doesn’t require an actual person’s name. 

You could fill in the blanks with anonymous study numbers or other de identified info if you were using it in a real research setting.

### 3/5 — Useless

*2025-08-22*

App is pretty much useless. After completing the 3 minute test there is no way to view results. It doesn’t log your session. No way to look at past results. Why is this an app?

### 1/5 — Can’t even start without providing PII

*2024-10-29*

Right off the back the problem I have with this app is that it requires you to enter PII (First and Last Name) before you can do anything.
If it is a true research app then PII should not be collected as part of the app unless there is opt-in / opt-out information clearly stated upfront.
Additionally, the app itself does not follow the standard PVT subject stimulus model, input mechanism, or discriminate handiness.
