Description
Emotional fitness–powered by your wearable, decoded by neuroscience.
SIX is the first emotional fitness app built for wearables like Apple Watch, Oura Ring, WHOOP, Fitbit, Garmin, and more. It shows how your brain and body respond to real-life moments, so you know what boosts your mood, energy, and clarity.
Backed by 20+ years of neuroscience, SIX measures bio signals linked to oxytocin and dopamine—neurochemicals fueling motivation, connection, and wellbeing. It helps you identify the experiences that make you feel focused, energized, and fully alive.
No journaling. No guesswork. Just real-time, brain-based insights—delivered with the wearable you already use.

*Real-Time Emotional Fitness Scores: See how your brain responds to everyday activities with live Value (emotional connection) and Safety Scores (comfort vs. anxiety).
*Daily Key Moments: Identify peak experiences your brain flags as meaningful–science shows we need 6 daily to thrive—SIX helps you uncover them.
*Personalized Insights That Fuel You: Discover what boosts your energy, mood, and focus—so you can repeat what works and shift what doesn’t.

*Works with Popular Wearables: Connect seamlessly with Apple Watch, Fitbit, WHOOP, Garmin, Oura Ring, and more.
Why It Works
Emotional fitness is built on meaningful moments that trigger the release of oxytocin and dopamine—neurochemicals essential for connection, resilience, motivation, and joy.
SIX uses your wearable data to detect those moments in real time. By interpreting bio signals through the lens of neuroscience, it reveals how daily experiences shape your mental clarity, confidence, and emotional wellbeing.
Science shows we need 6 emotionally significant experiences daily to truly thrive. SIX helps you recognize and create more of them—no journaling, guessing, or extra effort required.
Who It’s For
SIX is for anyone who wants to feel better, think clearer, and live more intentionally—using data from a wearable they already use.
Great for those who:
-Track sleep, steps, recovery, or heart rate
-Care about emotional health, self-care, energy, & clarity
-Want to reduce stress or prevent burnout
-Are into biohacking, habits, or performance optimization

Ratings and Reviews
Mostly Great
So far I’m really enjoying this app. The only issue I’m having is it disconnects during my workouts when my iwatch connects to Peloton. I’m not sure if this is a me problem or n app problem. I’d love to have the app connected throughout my workouts as I feel like I’m missing out on some valuable feedback.
Developer Response ,
Hello, and thank you so much for this review! We're sorry to hear about the issue you are encountering with your app disconnecting during workouts. Unfortunately, when the Apple Watch enters a workout mode, it disables our app from being able to capture that data we need to surface your Key Moments. We're actively exploring ways to improve this functionality, and welcome continued feedback!
Cool app when it works
Could load the app on my phone and watch, but am unable to create an account; every time I try to and enter my email, a message pops up telling me to check my InBox for a message with a “magic link” to register. Have tried a dozen times over the last 48 hrs and so far no message with a magic link (despite double-checking that my email address is correct, as well as checking my spam folders). Therefore unable to register. Meanwhile, the Watch app works sometimes, and other times stops tracking. This has happened three or four times in the past two days; have had to reload the app and restart my devices. When the app works, it’s been interesting to see the data. In this early stage of development though, it’s just too frustrating to use. I may check back in in a few months to see if it’s improved, and if it will finally allow me to register.
My new best friend
I love this neuroscience based app. It’s an easy, fascinating and transformative tool to support emotional fitness and well-being. It passively measures my own and my clients’ key moments of focus, motivation, and connection, providing surprising even startling learning moments every single day about what truly engages or disconnects us. With super UI/UE, the objective data the app provides and the simple, profound steps to Increase joy are invaluable. SIX brings me reflection and insight every single day, it’s like having a funny, wise best friend who really cares and gives seriously good advice as well. Bravo and thank you!
