BiAffect3 is the new and improved version of our award-winning BiAffect app, part of a multi-year mood-tracking research project developed by researchers at the University of Illinois at Chicago and funded by the National Institute of Mental Health. BiAffect3 • Track your mood and neurocognitive functioning with your iPhone. • Use keystroke dynamics and sensor data to gain insights into your mental health. • Help researchers develop new tools to improve the diagnosis and treatment of mood disorders. How does it work? BiAffect3 uses a custom-built virtual smartphone keyboard to collect keystroke metadata—such as typing speed, errors, and pauses—but not typed content in order to preserve user privacy. This data is then analyzed using machine learning algorithms and other statistical techniques to identify patterns that are associated with different mood states. Who is BiAffect3 for? BiAffect3 is for anyone who is interested in tracking their mood and neurocognitive functioning. The app is particularly useful for people with mood disorders as it can help them to identify early warning signs of an episode and take steps to prevent it, but it can be used by anyone who wants to learn more about their individual emotional and thought patterns. How do I get started? To get started with BiAffect3, simply download the app and create an account. The app will then guide you through the setup process. How can I help? By participating in the BiAffect3 study, you can help researchers develop new tools to improve the diagnosis and treatment of bipolar disorder. Your participation is voluntary and confidential. Download BiAffect3 today and start tracking your mood and neurocognitive functioning.

Living with OCD means managing more than habits. It means tracking intrusive thoughts, mental loops, compulsions, rituals, and anxiety that can take over your day. Ocetra helps you log what matters so you can break the cycle with insight and structure. Ocetra is an OCD tracker built for real life. Whether you are in therapy, practicing ERP, or starting to understand your patterns, Ocetra gives you a clear, judgment-free space to track progress, triggers, and goals. LOG OBSESSIONS AND THOUGHTS Track unwanted thoughts as they happen. Use categories like contamination, harm, symmetry, relational, religious, or taboo OCD. Rate distress and add notes to build awareness and reduce confusion later. TRACK COMPULSIONS Log rituals like checking, washing, counting, repeating, or seeking reassurance. Mark how long they lasted and what triggered them. Identify patterns and see when rituals go up or down across time. BUILD ERP GOALS Create exposures, track pre-task anxiety, and log whether or not you completed them. Record distress before and after. Build ERP consistency and confidence without guessing what you did last time. UNDERSTAND TRIGGERS Log internal and external triggers including thoughts, places, people, or random cues. See what situations bring up spikes so you can be prepared or discuss them in therapy. TRACK MOOD AND FUNCTION Log how OCD affects your mood, energy, and ability to focus, socialize, or rest. Add sleep, irritability, or avoidance patterns. Build a full picture of how OCD shows up in your daily life. REVIEW PROGRESS Charts show distress ratings, trigger frequency, completed ERP goals, and compulsion logs over time. Get a clear sense of what is improving and what still needs work. Even small wins count. SHARE WITH THERAPY Export detailed logs in PDF or CSV for therapists or psychiatrists. Bring structured data to CBT or ERP sessions. No more trying to remember what happened or how it felt. APPLE HEALTH INTEGRATION Sync sleep, heart rate, and mood data through Apple Health to spot trends.
