**Mood and energy, tracked together** Most mood trackers only ask whether you feel good or bad. Even Mind also asks how much energy you have, because changes in energy and sleep are often the first signs of a shift. One tap on a simple grid captures highs, lows, and mixed states like "bad mood, high energy" that a single scale misses. Made for Bipolar I, Bipolar II, and cyclothymia, and helpful for anyone who wants to understand their ups and downs. **Bring real data to your appointments** - Create a free Doctor Report: a clear PDF of your mood, energy, stability, and sleep over the last 30 days to 6 months - Share it with your psychiatrist or therapist in seconds, so you can show them what happened instead of trying to remember **Spot shifts early** - A stability score shows how much your mood swings between days and within a day - Log as often as you need, even several times a day - See mindfulness, workouts, and steps from Apple Health next to how you feel (Even Mind Plus) - Get insights on your patterns, like how sleep affects your energy **Simple on hard days** Logging takes seconds, with no long forms or symptom checklists. Add notes, people, and places only when you want to. **Private by design** No ads. No account. We never sell your data. Your data stays on your device and in your private iCloud. Insights (Even Mind Plus) is an optional feature and off until you turn it on. When you use it, your entries are sent securely to OpenAI to create your insights and are not used to train AI models. **Even Mind Plus** Even Mind is free to use, including Doctor Reports. Even Mind Plus unlocks AI Insights, custom themes and advanced charts. Even Mind is a tracking tool. It does not diagnose or treat any condition and is not a substitute for professional care.

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.
