This app is for users with a Quenza account. If your login details do not work here, you are likely using the legacy Quenza Classic platform which you can access through the Quenza Classic app. Quenza is an application for both client and practitioner. It allows professional practitioners (like therapists, coaches, counselors, and social workers) to easily build beautiful ‘activities’, such as worksheets, exercises, psycho-education, intake forms, reflection prompts, and surveys, and digitally share these with clients. These activities can be bundled into care programs – timed series of engaging exercises that are shared with clients via email or as in-app notifications with automated reminders. All client activity and results can be accessed through the client dashboard so the practitioner can monitor and stay on top of their clients’ progress. The main reason practitioners are working with Quenza is to keep clients engaged between sessions with custom homework exercises, reflections, meditations, and interventions. Other reasons include educating, onboarding, and assessing clients, evaluating their progress or the effectiveness of sessions, or simply to inspire them.
