Why this matters

In manageable amounts, stress can help us focus, respond, and perform. But when stress becomes prolonged or overwhelming, it can quietly affect concentration, sleep, mood, productivity, and overall well-being.

Dawn DTx is built on a simple idea: the better we understand our stress signals, the better equipped we are to respond to them. The 5-Day Brain Health Challenge gives you a clear, practical way to start noticing those signals and taking more informed action.

How it works

Each day takes only a few minutes. At the end of the five days, you’ll receive your report, turning invisible signals into something you can see, understand, and act on.

  • Check-in

    Complete a daily stress check-in

  • Measure

    Self-report how you’re feeling and complete a short facial biometric reading through the app

  • Learn

    Receive a personalized stress report

Your personalized stress report

Your stress has a pattern, and your report will show you what it is. Through Dawn DTx, you’ll receive a clearer picture of your stress signals along with potential next steps toward everyday brain health.

You’ll also see how your results compare to other participants in the challenge, and to your own group of friends, giving your numbers meaningful context. No guesswork, no generalizations, just your stress, explained.

Built on science, made for everyday life

OBI helps move brain health innovation into the real world. Dawn DTx brings that innovation into a simple, app-based experience that helps people measure, reflect on, and better understand their stress. Together, OBI and Mobio Interactive make the tools for managing your own brain health more accessible, practical, and personal. Dawn DTx is a science-led, human-centred app, available now and suitable for ages 16 and up.
