Four apps · one health picture
Train hard enough and everything else has to keep up.
XR is one system across four apps: training load sets your fuel, fuel sets the week's prep, and your labs say when to back off. The complete picture — not four trackers that never speak to each other.
iPhone app coming soon to the App Store.
Taper begins week 11
One loop, not four subscriptions
Each app writes something the next one reads. That is the whole argument for a suite: the complete picture only exists when training, fuel, food and bloodwork are the same record.
- Race date
- Training load
- Fuel targets
- Week's prep
- Lab markers
- …and the coach adjusts.
XR Fit
On iPhoneThe coach that writes the session you can actually do today.
It builds from the equipment in front of you, prescribes a target effort for every set, and moves the weight when your reps and RPE say it should. Strength, running, cycling, rowing, swimming and Hyrox are treated as one training life, not six apps.
- 869 exercises, each with equipment, grip setup and coaching notes
- Target RPE per set, adjusted from what you actually logged
- Race date drives the block — build, peak, taper
XR Fuel
In buildFuel that follows the plan, not a generic calorie goal.
Macros, calories and hydration on one dashboard, with targets that move as race week approaches — carb-loading when it matters, recovery after. It reads the training load XR Fit already wrote, so you are not entering your week twice.
- Targets shift with the training block, automatically
- Hydration and carbs weighted for race week
- One dashboard — no manual re-entry from your training app
XR Kitchen
In buildThe week's targets, turned into one prep session.
Kitchen takes the macros Fuel is already tracking and turns them into a shopping list and a single prep block. The failure mode it is built against is the one everybody has: a perfect plan and nothing in the fridge on Wednesday.
- Meals derived from the week's real targets
- One shop, one prep session, no daily decisions
- Adapts when the training week changes
XR Health
In buildThe markers underneath the training.
Labs and protocol adherence, tracked over time and lined up against your training load — so a bad block has somewhere to be explained. XR Health records what you and your clinician decide. It does not recommend protocols, and it never surfaces a dose.
- Lab markers trended against training load
- Adherence tracked, never prescribed
- Your data stays yours — per-athlete isolation, always
Tracked over time. Not medical advice, and never a dose.
869
exercises in the library
Every one carries equipment, grip setup and coaching notes — which is what lets the coach write a session you can perform with what you have.
Counted from the shipped exercise database on 15 August 2026, not an estimate. It is the only number on this page we ask you to take on trust, and that is how we counted it.
What we are not claiming
No ratings, no press quotes and no advisory board — XR is new and has none of those yet. XR Health tracks labs and adherence; it is not medical advice and never surfaces a dose. Decisions about a protocol belong with you and your clinician.
Start with your next race.
Put a date in, and the training block, the fuel targets and the week's prep follow from it.
