Just what I needed!

Too often do mental health apps fail the "practical world test". This app passes with flying colors. Its ease of use surpasses other clinical scale apps I have tested. I cannot wait to see what the author has in store next for tracking client outcomes.

Great app!

This is so convenient to have access to psychiatric scales on my phone with the ability to email test results! I’d like to see more scales on the app in the future.

Can't contact developer

I downloaded the app on 4 separate iPads, all running up to date software, and it crashes on every single one before it even fully loads. Works on my iPhone just fine. And there's no contact information anywhere for the developer so I can contact and trouble shoot. I really like the app but it's useless if I can't have clients take questionnaires on the iPad I have provided.

Developer Response ,

I appreciate you reaching out and I sincerely apologize for your frustration. I’d like to personally troubleshoot this issue with you. Shoot me an email at bill@drlemley.com and we can go from there. In “settings” there is a way to contact me but I’ll brainstorm ways to be more available for app feedback and questions.
