Woebot® Evaluation

"Woebot is an automated conversational agent (chatbot) who helps you monitor mood and learn about yourself." Evaluated: December 2019

The evaluation below is an example of the types of information you may find when using our Model to assess specific apps. These sample evaluations are not intended to enable you to make a decision about choosing these specific apps for actual use, as such a decision is a personal one that you will make based on your own unique preferences, needs, and evaluation. We strongly encourage you to download these apps for yourself and use our Model to conduct your own assessment.

These evaluations were completed December 6th and 7th, 2019, and are based on publicly available information found by our Panel at that time. In June 2020, APA's contacted the app developers and offered to them an opportunity to provide feedback on these assessments. Comments from developers who responded are included here. These comments do not necessarily reflect publicly available information at the time of the original assessment or presently.
