About Diorama
For athletes with more races ahead.
Training should account for the person doing it. Diorama brings your abilities, equipment, goals, and recovery into sessions you can review and choose.
Why it exists
Masters athletes are still racing and training seriously in their 40s, 50s, and beyond. They also carry old injuries, busy schedules, and decades of context that a generic training plan cannot see.
Some context lasts beyond a training block: movement options, equipment, and lasting physical limitations. Other context changes with the day: sleep, soreness, and available time. Ray uses both when proposing sessions, while you keep control of what it remembers and what enters your plan. Para athletes, masters athletes, and athletes training through injury bring different needs to that same idea.
The metaphor
Your body is a landscape.
A diorama is a constructed scene you observe from every angle: terrain, light, weather, and time of day. The app does the same for gait, recovery, sleep, pain, labs, and training. It gives you a landscape you can read without turning it into a leaderboard.
How we approach it
Practical over theatrical
Lead with useful help. If a feature doesn't make a real decision easier, it shouldn't be there.
Guidance without guilt
Design for imperfect weeks, missed sessions, and human variability. Good coaching adapts to the athlete, not the other way around.
Context over pressure
Bring pain, recovery, readiness, and planning together so decisions feel grounded and free of shame.
Privacy with restraint
Local-first by default. AI boundaries are clear. Your data is not the product.
Who built it
Designed and built independently by Dylan Marks, drawing on 25 years in healthcare software and his own experience training through injury.
“I built this because I needed it. I was training through injury, approaching 50, and every app I tried either dumped data on me or coached hard with no idea what was actually going on in my body or my week. I just wanted to know what to do today — without feeling judged for being human.
I've spent 25 years building healthcare software, where careful handling of personal data isn't optional. That thinking is built into Diorama. You should get to choose who sees your health data.”
