The Athlete's Operating System
Train like the sport demands.
One training log for people who lift, fight, run and play, instead of one app each. Say your session out loud, get one readiness number in the morning, and ask a coach that has read your training history. iPhone, iPad and Apple Watch.

You came here because
Most apps only count one kind of training.
- You lifted Monday, sparred Tuesday, ran Thursday. Your lifting app saw one session that week and called it a light week.
- So you keep two apps and a Notes file, and none of the three knows what the other two cost you.
- Then something starts hurting and you cannot say whether you ramped too fast, because nothing ever added it all up.
See it work
Three steps. Three screens.
In the order you would hit them. These are the app's own screens, with the app's own numbers on them.
Two of those no longer need your phone at all. Dial reps and weight on the Apple Watch and confirm the set with one tap, or ask Siri for your readiness on the way out the door. On iPad it is a real layout, sidebar and all, rather than a phone screen stretched to fit.
How to read the number
What readiness and workload are, and what they aren't.
- Readiness is an estimate. It comes from your HRV, sleep and resting heart rate in Apple Health, from your morning check-in, and from what you have actually been training, each read against your own baseline. Training counts by the size of the jump rather than the effort, so a hard week that is normal for you costs nothing and an unusual spike above your own norm takes points off. A guide for how to train today, not a verdict on your body.
- Workload counts every modality. Recent work is measured against your own baseline, not a population average. On most apps that baseline only sees one sport, which is why a heavy lifting week can hide inside a running app. Here the roll, the run and the squat session land in the same total.
- Neither one diagnoses an injury or predicts one. Versus is a training log and a planning tool, not a medical device. The load trend tells you the ramp is steep; it does not tell you that you are hurt, and it is no substitute for noticing that you are.
Readiness is free on every tier, every day. How it is calculated →
The coach
It asks before it prescribes.
Sensei runs on Anthropic's Claude, with your recent sessions, your per-exercise progression, your current camp, your readiness and your PRs in front of it. That is the whole trick: it answers about your training instead of about training. Ask it for an exercise swap and it wants to know why first. Tell it what happened in a round and it tags the positions and the finishes.
Elite tier. What it can do →
Who's it for
One product. Five athletes.
Same app underneath. Pick the one that sounds like your week.
I fight.
MMA, BJJ, Muay Thai, boxing, wrestling. Rounds and sRPE, a skill tree that goes position by position, camps and fight week.
Built for fighters →I lift.
PRs detected as you set them, your lifts against strength standards for your bodyweight, sex and age, a DOTS total, and openers through third attempts planned for meet day.
Built for lifters →I run, ride, or swim.
One recent race gives you easy, threshold, interval and repetition paces, and an equivalent time at every distance from 1500m to the marathon. Structured workouts run with live targets.
Built for endurance →My sport is the training.
18 sports, logged in seconds with sRPE and a score, 14 of them with a full skill tree. Off-field lifting periodised around your season, and readiness that knows when the game is.
Built for sport athletes →I do more than one of those.
Lift in the morning, sport at night. Two seasons stacked. Both count toward the same load, so neither one is invisible.
Hybrid athletes →Most people use two of the five loggers and ignore the rest. That is the intended use, not a failure of the app.
Pricing
Free forever is the actual plan.
All five loggers, daily readiness, the skill tree, nutrition, imports and the Watch app cost nothing and always will. A session plan each morning is free too. Core at $9.99/mo adds per-system load, plateau detection and training camps, and plans the day on a larger model. Elite at $14.99/mo adds Sensei, a coach you can ask why, and a programmed week of skill drills for your sport.
