Meet Ray, your new personal trainer. You work with Ray like you'd work with a human trainer; tell Ray your goals, restrictions, or injuries, and it develops a custom plan for you. During workouts, Ray coaches you through every set with real-time voice guidance while computer vision counts your reps. And Ray adjusts on the fly. Short on time? Different equipment? Ray's got you. It's the flexibility of a personal trainer, available anytime, anywhere.
We created Ray because we wanted to make it easier (and less intimidating) for more people to exercise regularly.
Here's the thing: strength training is one of the best things you can do for your long-term health—but most fitness apps are built for people who already know what they're doing. We wanted to build a personal trainer for everyone else. Someone to guide you, adapt to you, and help you build better habits.
A bit about me: I've spent many years creating products and experiences for people at places like IDEO, Formlabs, and PillPack. At PillPack, we focused on helping people take their medications regularly. That experience taught me a lot about building products that help build healthy behaviors. Ray is the same mission, different habit.
Where we are today: 📱 Live for 8 months ⭐ 4.88 rating in the App Store 🏋️ Thousands of people trained 💪 Users rate our workouts 4.7 on average 🔁 If someone does 2 workouts, they usually do 10—that retention makes us incredibly proud
What makes Ray different: 🗣️ Talk to Ray like a trainer—set goals, mention injuries, change your workout mid-session 🎧 Real-time voice coaching guides you through every set 🧨 Dynamic Programming understands what you've been training and focuses on the right areas of your body 🎯 Programming focuses on strength training, light conditioning, & stretching 📷 Computer vision counts your reps on core exercises ⚡ Adjusts on the fly—short on time, different equipment, just tell Ray 🧠 Detects unfamiliar exercises and walks you through them 📲 Syncs with Apple Health to understand your other activities 💬 Text nudges to keep you consistent
We'd love your feedback: Everyone trains differently. Ray is early in its journey, and right now, we have proven flows focused on helping newer users navigate fitness. And we're adding more expert flows and features soon. We'd love to hear how Ray could better adapt to your style—and where you'd like to see the product go.
Give Ray a try and let us know what you think! Colin + the Ray team (7 of us in Cambridge, MA) 🚀
Hey there! This app is so amazing! Any plans to release it on Android? Thank you so much!
Very cool idea! AI replaces another profession, and that’s great news for our future.
Congrats on the launch! Very nice landing page. For me, the hardest part is getting started and staying in a routine. Look forward to trying this out.
I use a trainer and go to the gym, but needed something extra at home. After using Ray just a few times, I already start thinking ooh I could squeeze a workout in right now. I'm not sure what they've done, but I'm already "hooked" - unusual for me. I like the 20 minute workouts and that I can choose no equipment. I like the constant timers so I know exactly where I am in the workout.
From a design perspective, Ray feels intentionally understated.
Instead of trying to explain everything up front, the interface seems to trust progressive disclosure — letting clarity emerge through interaction rather than through dense UI or copy. That choice usually signals a team that’s thought carefully about first-time user anxiety.
As a first impression, the product feels calm and confident, which is a refreshing contrast to many tools that try to do too much visually.
Ray is AMAZING. Super simple to follow and the most important part, it fits my life. Yes, I know I should set up a schedule and follow it with discipline. But that is not how my life is at the moment. With Ray, I have been able to exercise at home when I couldn't run, at 11pm when I didn't have time during my day, in my hotel room when I was traveling, shortened my exercise time when it was too much. I love the text suggestions and facts that it drops every few days. Love that I can work out with my music and no equipment and there are other options when I do have equipment! I started with only 20 minutes 3 times a week and I can feel the difference. I would never have that flexbility with a trainer. Thanks Colin and team.
I am at session 29 and I'm finally getting into a routine, the personalized voice experience really makes a difference.
Ray has been such a game changer when it comes to staying consistent with workouts. There's no more fussiness when it comes to figuring out your workout and the tailored customizations creates a more joyous and personable experience. Love the friendly reminders and enjoy the "post-mortem" that lets you honestly reflect on how the workout was. As I look to lean more into weightlifting in 2026, I can't wait to have Ray as a sidekick in the gym!
Ray is great, allows to customize workouts. I am recovering from an injury and Ray was able to tailor the workout to my specifications. I like how there are video looped to show proper form. Great work to the Ray team!
This app solves the huge issue of “what do I do today”. I literally talk to it and in 30seconds I have a custom workout. I shut my brain off and let it do its thing.
As a working mom with a very full plate day-to-day, Ray has been a godsend...and it's shifted a persistent blocker in my brain around daily movement. I've found that fitting in a 20 minute workout when / where I can makes a world of difference in keeping me consistent—especially because I'm a recovering perfectionist and former "all or nothing" gym go-er, which had proven totally unsustainable for my current phase of life and evolving mindset around movement. I want to live a long and healthy life with strength and mobility at the forefront, and Ray has shown up as a true partner in helping me build new habits that support this mindset. Ray also takes real-time feedback well, if I have small notes to share about my experience after a workout. My daughter even joined me for a couple of sessions at home over the holidays, which was a lot of fun. :) Excited to keep it going in 2026, and to see how Ray continues to evolve.
Congrats @colin_raney and team! I know Colin personally, but I’ve been using Ray on my own and it’s the first time I’ve been consistent and excited about home strength training. Feels like a trainer in your ear, works great with music, and love how it adapts to time, equipment, and anything else you throw at it. Excited to see it grow!
It is not available in the Apple App Store for India. Any plans to make it available?
Looks like a great app, however not yet available to download in the UK. Will it be coming here anytime soon?
Ray is the best! My partner and I have been using Ray for a few months now, and we love how versatile the workouts are, depending on what we need that day. Excited for what's to come in 2026!
