There are a few things you can do to help.

First, if you have any suggestion to make PD Diary better, please let me know. (FaceBook)

Second, you can share the app on social media.

Third, you can share with other people you know.  For instance, at a support group meeting.  If you would like a little presentation, or a brochure, I could help put something together.

Fourth, if you find PD Diary useful, please leave a review on the Google Play Store.  Reviews help other users find the app.
