SIX turns the Apple Watch or wearable you already own into a personal dashboard for mental and emotional wellness. Using 20+ years of neuroscience, it reveals what lifts your energy, lowers your stress, and helps you thrive.
You’ll see exactly how your brain responds to everyday moments—so you can do more of what moves you and less of what drains you.

• Daily Key Moments: Automatically capture the six most emotionally meaningful moments your brain experiences each day.
• Mood & Energy Forecasts: Know how you’ll feel tomorrow—plan, recover, and perform with clarity.
• Local Recommendations: Personalized suggestions for local finds, media, and podcasts that are likely to create Key Moments for you.

WHY IT WORKS

I honestly feel like SIX understands my brain better than I do! 👀 This is the first legit neuroscience app I’ve found (or that exists?) that allows me to measure how my brain is reacting across my day so that I can discover the moments that matter the most to ME. I’m constantly on the go and can’t get into journaling (sorry, not my cup of tea) so their Key Moment feature has been a game changer for reflection and caused me to be a lot more self-aware of the things that I need to prioritize to make my day/week/life better. My Key Moments often happen during things that I know I get really into - like painting or solving problems at work- but other times it surprises me and lets me know that activity/moment was valuable to my brain and I should be prioritizing them more often! My guitar has been collecting dust and I finally picked it back up the other day and got a Key Moment- so I’m going to try to weave in time to shake off the rust and play more. Also the mood and energy forecast is super cool- it predicted me getting in a slump when I was not taking enough time for myself. Back on track now but now I know I can use it to try to circumvent low mood days proactively by trying to get more Key Moments! Works great with my Garmin which is now getting a ton more love- just had to pair it and now it starts collecting when I slap it on in the morning- no extra steps. Really really love this app and excited to see what else it can uncover about myself!

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!
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.
