Introducing Mimir, the pioneering sport psychology app designed to assess the psychological climate of your team or group. With its high-frequency, low-burden data collection approach, this app offers coaches invaluable insights into the hidden psychological dynamics of their team, empowering them to optimise performance effectively. The Team Climate is created from player perceptions of the psychological factors influencing performance in the sport environment. Team Climate identifies positive and negative performance influences from both internal (self) and external (social) sources. Team Climate has a high frequency collection rate due to it being affected by time, situation, and case. All data is anonymised to help create a continuous feedback loop. Wellness is the act of practising lifestyle behaviours on a daily basis to attain better sporting performance outcomes. Wellness Insights help you understand your teams performance through real-time analysis of player wellness. Insights show changes in key performance indicators providing coaches with the power to improve performance.

Rather than relying on the loudest voices in the room, Every Voice helps surface the collective perspective of the team in a balanced and coach-friendly format. Powered by Lumen AI, Every Voice draws intelligently on the team’s wider digital profile, including personality information, psychological climate data, and perceived wellness trends, to help coaches better understand the context behind player feedback and identify the most meaningful areas for action. Each report provides: - Clear, high-priority coaching insights based on anonymous player responses - A confidence indicator to show how strongly the findings represent the group - Response completion data to support interpretation - Neutral, psychologically safe language designed to promote reflection, not blame - Secure historical reports stored for future review - Every Voice helps coaches listen better, understand more, and act with greater confidence.

Wake up tired without knowing why? Headaches that hit out of nowhere? Substrata watches the noise, weather, and air around you, then pairs it with your sleep, heart rate, and HRV — so you can see exactly what's affecting how you feel. The analysis runs entirely on your iPhone using Apple Intelligence. After about two weeks, the on-device correlation engine starts surfacing connections — barometric pressure drops that match your migraine days, bedroom noise that quietly steals your deep sleep, weather patterns that drag down your HRV. Plain-English explanations you could share with your doctor.
