Launched this week
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.

Hey Product Hunt! 👋
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_raney Ray has taken over my fitness life. The only app I use every day. I am probably biased. But it’s completely changed how I exercise and increased the consistency. It’s not one feature. It’s all the service design touch points and how they come together to create a true personal trainer in an app.
Ray
@elliot_cohen You sir, are a legend! thank you 🙏
@colin_raney The real-time adjustments are impressive. Most apps break the moment life gets unpredictable — this feels built for that reality
Congrats on the launch
Very Nice. Also loved the way website is designed. Any plans for an android ?
Ray
@bekjon_ibragimov Thanks for the kind words. We definitely have Android on the road map. (My cofounder, Rich was one of the co-founders of Android...so it's got to happen 😉)
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.
Ray
@jordan_bresler aww TY Jordan, appreciate you.
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!
Ray
@charlotte_whalen Thank you Charlotte!
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!
Ray
@jeffvlahos thank you Jeff!
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.
Ray
@jeff_ledell TBH, letting Ray make all the decisions is the best part!
Looks like a great app, however not yet available to download in the UK. Will it be coming here anytime soon?
Ray
@joshh_founder Hopefully later this year? The main hurdle is that Ray does a lot over text, and we have to figure out what that means outside the US cell system
