Personally I find the website layout terribly confusing. An App could address that. They seem to be easy to get, do and have.

Here's the response I received from Support:

"Thank you for contacting MyParkinsonsTeam.

We do not have a mobile app for the site yet. We recommend you use the web browser to view www.myparkinsonsteam.com from your phone or device.

Best,
