One app holds everything
behind how you perform.
Onyx Performance OS keeps your training, your recovery, your food, your sport and your test results in one app. The parts read from each other, so the check-in you answer in the morning changes the weight the app suggests in the afternoon, and the food you log through the week shows up in the report you get on Monday.
The first seven days are free in the app, then $24.99 a month or $199.99 a year. On the web you pay by card today. Cancel any time and keep access to the end of the period.

Today comes first
Your readiness score, the session planned for today and one line on what your readiness means for your loads.
What it covers.
Train
Follow a program chosen from your goal, experience and available days, or build your own. Every set carries a recommended load calculated from your previous sessions, your check-in and the set before it, with the reason written next to it. The library holds over 400 movements with video and coaching cues.
Recover
A morning check-in asks about sleep, soreness, energy and pain, and explains every scale it uses. If you report pain, the lifts that load that region are reduced for the day. With seven nights of Apple Health data, a recovery reading compares your sleep, heart rate variability and resting heart rate with your own baseline.
Eat
The food diary searches 440,000 foods by name and brand, scans barcodes and remembers what you log. Every entry carries its vitamins and minerals, and you can tap any nutrient to read what it does in the body, which of your foods supplied it and which foods carry the most.
Your sport
Practices, classes, matches, runs and walks count toward your week, with distance and pace recorded on runs, rides and walks. A team schedule entered once makes your sessions appear before they happen, ready to confirm with your effort for the day.
Test
The home test day walks you through tests you can do where you train, scores them against published norms for your age and sex, and shows the change every six weeks. Members tested at the Lab see their Onyx Score and the profile behind it.
Your week
Every Monday you receive a report on the week: sessions, sport hours, sleep, food and the one change the numbers support. The Progress tab opens with your current week, then your strength on every lift, your test results, your body weight, your classes, your training load and your readiness.
How a week works.
- 01
Check in each morning.
You answer a few questions about sleep, soreness, energy and pain. That reading, together with last night's sleep from Apple Health, sets how heavy today should be.
- 02
Train and log.
Each set comes with a recommended load and the reason for it. You lift, rate the set Easy, Medium or Hard, and the next set adjusts. Your food, your sport and your weigh-ins go into the same record.
- 03
Read the week.
Every Monday the report puts your sessions, sport hours, sleep, food and readiness side by side with the week before, and names the one change the numbers support.
Anybody who wants a more informed way to train.
Starting out
You get a first program that fits what you have, loads that start light and move when you do, and every scale explained before you use it.
Training alone
You get the number on the set, the reason behind it and a report that reads your week back to you, which are the three things a coach would give you between sessions.
Athletes out of season or away from Miami
You get the same app and the same loads the Lab's athletes use, with your season, matches and practices in the record.
Already tracking everything
You get one place for training, sleep, food and testing, and one Monday read that says what to change.
