Highly recommend this app

It may not be "pretty," but it is highly functional and keeps good records. Its helpful for reminding me what a skill actually is because if you click on a skill a definition will pop up. You can also (somewhat) customize you DBT card, which can be saved and sent to whomever you want via email. I have recommended this app to therapist and those "working the DBT" life.
