You’ve meditated before. Did it work? Be honest…you don’t actually know. Equa does. Equa is a meditation app that turns your practice into something you can measure. Using only the motion sensors in your phone, Equa tracks your breathing while you meditate and turns it into feedback on what actually changed during the session. No watch, no ring, and no headband needed. Using your respiration data, you can now see how your practice went, and watch your meditation skills develop over days and weeks – so you can tell whether it’s working instead of guessing. If you are new to Equa, you can try the app for free. After the trial, choose your own price on our sliding scale, or become an Equanaut and make Equa possible for someone else! Equa needs no additional hardware. Simply rest your phone on your chest and let the sensors inside do the work. How it works: Meditation Insights Equa reads your breathing from your phone’s accelerometer during a session and shows you what changed. You get your breath rate in breaths per minute, how it shifted from the start of the session to the end, and where that sits relative to your own baseline. The respiration algorithm was developed with researchers at Carnegie Mellon University. Breath Rate Breath rate is one of the clearest physical signals that a session is doing something, and Equa tracks it every time you sit. Trends Single sessions vary. Practice shows up over weeks. Equa charts your breath rate and session history over time so you can see your progress over time. Science We didn’t just make this up. Equa’s Chief Science Officer, Dr. David Creswell, runs the Health and Human Performance Lab at Carnegie Mellon University, where he’s spent two decades studying how mindfulness training actually changes the body’s biological stress outcomes. One study found mindfulness training reliably lowered cortisol and blood pressure under stress. But participants didn’t report feeling less stressed – they just were. “How do you feel” was never going to catch that. So we built something that does. Training & Curriculum: Equa treats meditation the way a training program treats a physical capacity. Sessions ask you to stay with discomfort rather than escape it, because that is where stress resilience is built. The curriculum offers a structured path through Unified Mindfulness’s core skills: Concentration Power, Sensory Clarity, and Equanimity. Equa offers a science-backed framework for mindfulness training. What else you can do in the Equa app: Review any past session and its breathing data Set practice reminders that fit your schedule Follow guided sessions for stress, focus, and attention Track and build on your practice Equa provides products and services designed for general wellness and education purposes. Equa is not a medical device, is not intended to diagnose, treat, cure, or prevent any disease, and should not be used as a substitute for professional medical advice, diagnosis, or treatment. Breath rate measurement provides feedback on your meditation practice and is not a diagnostic tool.  After this, Equa offers two auto-renewing subscription options: Play what you want slider Price - Varying This subscription is for six months and auto-renews after six months. - Title of auto-renewing subscription: Pay as you go. - Length of subscription: 1 month - Price of subscription: Varying - Privacy policy can be found here https://equahealth.io/privacy-policy. - Terms of Use (EULA) can be found here https://www.apple.com/legal/internet-services/itunes/dev/stdeula.

Join Groundbreaking Climate-Mental Health Research The HEAT-MIND Lab app connects you to cutting-edge research exploring how rising temperatures affect mental health. By participating, you'll contribute to science that could protect millions as our planet warms. Why This Research Matters Climate change isn't just an environmental issue – it's a mental health crisis. Young adults are particularly vulnerable, experiencing a 3% increase in suicide rates for every 2°F temperature rise during the summer – that's an effect as large as what we see after major environmental disasters. That's why our research focuses on your age group. With global temperatures expected to rise by nearly 8°F by 2100, we urgently need solutions. The Challenge We're Addressing While we know heat affects mental health, we don't fully understand how. Does it disrupt sleep? Make it harder to think clearly? Interfere with exercise and socializing? Understanding these pathways is crucial for developing effective interventions. How the App Works As a participant, you'll wear small sensors that continuously monitor the temperature and humidity around you, along with sleep and activity trackers. Through the app, you'll complete regular surveys about your mood, depression symptoms, and cognitive performance over one month. For the first time, we'll see how real-world temperature exposures relate to mental health symptoms, sleep quality, thinking ability, and physical activity patterns in everyday settings. We’ll see if daytime versus nighttime heat exposure affects mood differently. We’ll also see if factors like gender, race, education, income, geography, or medications make people more vulnerable or protected. Real-World Impact Your participation will help us identify targets for practical, affordable interventions to maintain mental wellness during hot weather. We're committed to developing clinical guidelines that reduce human suffering as temperatures rise. Our Broader Mission HEAT-MIND Lab (Healthy Environments and Temperatures – Mechanisms in Neuropsychiatric Disorders) integrates lived experiences of people with mental health conditions into every aspect of our research. We're training the next generation of researchers and sharing our methods so scientists worldwide can advance this critical field. We believe in meeting people where they are, sharing findings through social media, news outlets, and community channels – not just academic journals. We're also developing training for mental health professionals to understand climate impacts on their patients. Be Part of the Solution This research prepares us for the mental health challenges of climate change. By participating, you're not just contributing data – you're helping build a future where we can protect psychological well-being in a warming world.
