Whether you're chasing a HYROX time, building strength around a career, or training in a body that changes month to month — Station Zero reads YOUR training, recovery, fueling, and (if you track it) cycle together. It tells you why today feels the way it does, what to do about it, and gives your coach the same view between sessions.
For every athlete · For every coach · For every gym · Performance (iPhone + Apple Watch) · Coach (iPad) · Studio (web)
Most fitness apps were designed around the same 25-year-old athlete with nothing else going on. Station Zero is built for everyone else — and works just as well for the 25-year-old too.
Career, family, sleep that varies, energy that varies. You want to keep getting better — but the same workout doesn't always land the same way, and you want the app to actually notice that.
Optional, athlete-controlled. If you choose to track it, your readiness reads and fueling targets account for where you are in your cycle — based on your own data, not population averages.
You've been at this 10, 20+ years. Your raw PRs don't move the way they used to. Station Zero shows effort-adjusted progress — the wins you're actually making, against your own baseline.
Race-prep tools, per-station splits, race-day prediction, training-load monitoring. Apple Watch guides every segment with live heart rate and pacing cues.
Not a medical device. Not for diagnosis, treatment, or prevention of any condition. Cycle tracking is athlete-controlled — never required, never assumed, never shared without consent. Built to inform training decisions, not replace medical guidance.
Not because of motivation. Not because of time. Because the apps they train with don't read their physiology, don't connect what they eat to what they're doing, and don't catch the early warnings before they become quit decisions. Station Zero exists to keep women healthy, fueled, recovered, and training intelligently for the next 20 years.
Most career-ending injuries are accumulated, not acute. The rotator cuff tear, stress fracture, or tendinitis that sidelines her for six months is usually visible weeks earlier — in patterns most apps don't watch. We watch.
The silent epidemic in women's training. Missed periods, bone density loss, mood collapse, infertility risk. By the time the symptoms show, it's been happening for months. We connect what she eats to what her training demanded — so she sees it the same day.
Training hard during the phase her body is most fragile leads to overtraining, burnout, and quitting. Her programming should adapt to where she actually is. Optional, athlete-controlled, never assumed.
Raw output declines with age even when fitness is improving. Without effort-adjusted progress, women interpret normal physiology as personal failure and quit. We surface the wins her stopwatch is missing — so she stays in the sport.
We're not another fitness tracker. We're the system that keeps her training, healthy, and progressing for the long arc — so dropout at 40 isn't the default.
Choose your role and see the jobs Station Zero helps you handle every day.
Most apps hand you data. Station Zero hands you an answer: "you're tired today, and your body has a reason — here's why and what to do." Calibrated to YOUR baselines, not a population average. Works for any sport you train — HYROX, CrossFit, lifting, running, hybrid.
You coach 30+ athletes. You see them an hour at a time. The rest of the week, you're trying to remember what each one did, how they felt, what's working, who's drifting. Station Zero ends that — you walk into every class already knowing the answer, you program next week from data instead of vibes, and the conversations you have with athletes finally have something behind them.
Memberships, scheduling, billing, comms — the basics that have to work. Plus retention intelligence that flags at-risk members before they cancel — fused from attendance, recovery, and training-progress signals nobody else can see. Athlete-count pricing — fair for small gyms, scales as you grow.
Independent coach or PT? Use Coach with Studio Solo Mode to manage programming, clients, sessions, progress, and billing without big-gym complexity.
Workout, recovery, attendance, and business data stay connected automatically.
The iPhone and Apple Watch app for workouts, readiness, HYROX race prep, progress, booking, and recovery.
Live class on one iPad, pre-class intel that ends the "how are you feeling?" guessing, per-athlete drill-in for week-to-week programming decisions, and coach-only conversation starters that make 1:1s land harder. The 23 hours between sessions stop being a blind spot.
The web dashboard for scheduling, billing, members, leads, reporting, and gym operations. Plus the full retention intelligence stack — at-risk roster with red/amber/green tiers, MRR-at-risk dollar count, per-member WHY-it-fired breakdown (Behavior · Body · Progress), and a Members Saved counter that proves the work is working.
No duplicate entry. No scattered athlete history. Each action makes the next one more useful.
The workout is published once to athletes, watches, and the live class view.
Watch and app capture effort, pace, splits, heart rate, and results.
Live signals and post-workout analysis reveal who needs attention.
Better coaching, visible progress, and connected operations strengthen retention.
Install Performance on iPhone and Apple Watch to try guided training, readiness, and HYROX performance tracking.
Try on TestFlight →See how Station Zero fits your classes, coaching workflow, and gym operations in a short pilot call.
Book a pilot call →Coach programs. Athlete trains on the Watch. Data flows back. Performance improves.
Anyone can log a workout. The hard problem is connecting training to recovery to race outcomes — and surfacing what actually works for each athlete.
Training → biometrics → race results → correlation → smarter programming. Every other platform handles one piece. We're the only one that closes the loop so coaches can see cause and effect, not just data points.
Official race import from results.hyrox.com. Station benchmarks against your gym. Standard-compliant scoring for Singles, Doubles, and Pro. Generic fitness apps bolt HYROX on. We built around it.
Per-athlete correlation engine surfaces why performance changes. Projections forecast where each athlete may be in 4/8/12 weeks. ACWR (acute:chronic workload ratio) flags when training load is above the athlete's usual range so coaches can plan recovery. Not a dashboard — a coach's brain, amplified.
Tap any metric — VO₂ Max, HRV, HRR60, Resting HR — to see what it is, why it matters, and where you rank for your age and sex. Athletes stop looking at numbers and start understanding them.
Station Zero connects what athletes do, what coaches see, and what owners need to run the gym.
Real-time BPM and HR zones on the wrist during every workout. Zone targeting, effort gauges, and pacing cues. The athlete trains smarter. The coach sees it all.
Step-by-step segments on Apple Watch. HYROX stations, AMRAP rounds, interval timers, rest countdowns. The Watch coaches the athlete through every phase.
See every athlete's results in real time. HR per station, duration, calories, RPE, round splits. Spot who crushed it and who needs recovery — instantly.
Daily readiness computed from HRV, resting HR, sleep quality, and training load. Recommendations from "Full Send" to "Rest Day." Coaches see who's recovered and who's not.
Per-station timing for SkiErg, Sled Push, Wall Balls, and every HYROX exercise. Compare sim to sim. Find weaknesses. Track improvement over months.
Predict race finish times from training splits. Compare station times to gym averages. Athletes see exactly where to focus to shave minutes off their HYROX time.
See what actually makes you faster. Station Zero correlates your training, recovery, and race data to surface patterns — like discovering your Fran time drops 12 seconds for every 10ms of HRV gained overnight.
Paste your results.hyrox.com URL. Station Zero parses your finish time, rank, all 8 run splits, and all 8 station splits automatically — then correlates the race with the training that prepared you for it.
ACWR, sRPE, and week-over-week trends — the sports-science metrics elite teams use to plan deloads. See when your training load is above your usual range so you can plan recovery before it accumulates.
Nutrition, hydration, sleep, training load, and (optionally) cycle — read together into one daily score. Athlete-controlled inputs, no data shared without consent.
The dashboard's hero is a one-sentence answer: "you're tired today, and your body has a reason — here's why and what to do." Cause + fix, calibrated to your own baselines, never a generic number out of context.
Optional, athlete-controlled. When enabled, fueling targets and recovery reads adjust to your cycle phase based on YOUR data — not a population template. Never required, never shared without consent. Disable any time.
Rate your effort 1–10 when you save the workout — takes 2 seconds. That single input is the spine of the whole intelligence engine: today's read, effort-adjusted PRs, training-load reads, the "this is normal for you" comparisons. Without RPE, the app reads numbers. With RPE, it reads YOU.
Connects what you ate to what your training is asking for. "Yesterday's hard session asked for ~600 extra calories — you ate 400 short. Today's effort may reflect that." Pulls macros from any app that syncs to Apple Health (MyFitnessPal, Cronometer, MyMacros, etc.) — you don't log twice. Cycle-aware carb adjustments when enabled.
Raw times don't tell the full story when life is loud or you've been training for 20 years. Effort-Adjusted PRs surface the wins your stopwatch missed — same time at higher effort is a win for the conditions you trained in.
Scores every member 0–100 for churn risk across THREE dimensions: Behavior (visits, no-shows, payment failures, never-activated new members), Body (HRV drift, sleep debt, training-load overload, cycle-phase mismatch), Progress (effort trend, PR cadence, coach-contact decay, effort-adjusted decline). Every other tool (Recovr, Keepme, Loyalsnap) reads only Behavior — Station Zero is the only one that catches athletes whose body is quitting before their feet do.
One tap on today's workout → OpenAI reads your prescribed blocks + sets and writes a 3-line coaching brief: what it trains, how to pace it, how to adjust to today's body. The synthesis serious athletes were already doing manually in ChatGPT — now built into the app for every workout.
Studio Dashboard tracks every athlete who moved from red/amber to green over the last 30 days. The number you show your accountant: "we saved 7 members worth $1,400 MRR this month because we caught them before they canceled." No other gym tool counts this.
Coach sees the same data their athlete sees — sleep, training load, recovery, cycle (if shared), progress trends. Plus the at-risk roster, pre-class member-intel pills on the live iPad, and one-tap "Mark as contacted" to log the intervention. The 23 hours between sessions stop being a blind spot.
A 33-minute Half Murph is just a number. We show you the round where you broke, the movement where you faded, and the second where the wheels fell off.
Cycling figured this out in 2005. Power-per-pedal-stroke became the gold standard. Every pro team uses it because without it you are guessing.
Running closed the gap in 2010 with per-kilometer splits and live heart rate. Rowing always had it via Concept2 per-stroke logging.
HYROX is six years old and its coaching tools are still at "remember what felt hard." Station Zero is the per-station power meter for hybrid fitness.
Wodify and BTWB tell a coach who finished and when. Station Zero tells them what happened in every minute of that workout, on every station. That is the difference between a logbook and a coaching tool.
Every workout generates actionable insights. The more athletes train, the smarter the platform gets.
Three forces converged to create this opportunity.
Clinical-grade heart rate sensors on 100 million wrists. Athletes already own the hardware. They just need the software.
From 175,000 athletes in 2023 to over 650,000 in 2025. From 5,000 affiliated gyms in late 2024 to 15,000+ by April 2026 — tripled in 16 months. Bloomberg called it the fastest-growing race format in fitness in March 2026.
Existing tools each solve one piece. Wodify (now an official HYROX partner for gym ops) handles memberships, programming, and post-class scoring. SugarWOD logs results. Whoop gives biometric data only to the athlete — the coach is locked out. None of them stream live in-class biometrics from the athlete's wrist to the coach's screen, and none capture per-segment HR for the post-workout breakdown.
From programming to performance insights in four steps.
Create or paste any workout. HYROX sim, AMRAP, For Time, intervals. Schedule it for any date.
Open Watch. Pick scaling level. Get guided segments with live HR zones, pacing cues, and rest timers.
Results sync to the coach dashboard instantly. HR, station times, calories, RPE, round splits.
Spot weaknesses. Adjust programming. Track training load. Coach with data, not guesswork.
HYROX and functional fitness is massive, growing fast, and underserved by technology.
Growing 7.5% annually. 15,000+ CrossFit affiliates, hundreds of HYROX training gyms, all needing better tools.
Target pricing. At 50 athletes per gym, that's $750-1,250/month recurring revenue per gym.
Conservative capture of the addressable market. Our performance advantage grows with every workout logged.
Every workout makes the platform more valuable — for the athlete and the coach.
After 3 months, they have a performance profile: HR patterns across workout types, station-specific times, recovery trends, PRs. That history doesn't exist anywhere else. Switching means starting over.
Training load data across the entire gym. Which athletes are peaking, who's at injury risk, how programming changes affected performance. This compounds weekly — the longer they use it, the more they depend on it.
Existing tools do pieces of the puzzle. Nobody connects coach, athlete, and real-time biometrics in one platform.

Station Zero isn't another workout logger. It's the only platform that closes the loop between programming, execution, and insight.
ROXFIT raised $1.9M building an athlete-only HYROX app. No coach dashboard, no gym platform, no team management. Station Zero is the only HYROX platform that serves both the coach and the athlete — closing the data loop between programming and performance.
Wodify's HR tracking requires Myzone chest straps ($100+ each) displayed on a gym kiosk. Station Zero uses the Apple Watch athletes already own — live HR on their wrist, not on a TV across the room. Zero hardware cost to the gym.
Whoop gives incredible biometric data to the athlete — but the coach never sees it. Station Zero routes HR, readiness, training load, and recovery data directly to the coach dashboard. The coach can finally use biometric data to make programming decisions.
No competitor delivers step-by-step workout segments with live HR zone coaching on the Apple Watch. BTWB passively records. Strava tracks after. Apple Fitness+ plays videos. Station Zero actively coaches the athlete through every station, rest, and round — in real time.
Features that make investors say "wait, it does that too?"
Set up a camera at any station. It auto-detects athletes via on-device face recognition, records their set, and saves the clip for coach review. Privacy-first — all processing on-device, no cloud.
Coach describes what they want in natural language. AI generates a complete workout template with stations, scaling levels, duration, and segments. Save, edit, publish in seconds.
Daily readiness computed from HRV, resting HR, sleep quality, and training load. Recommendations range from "Full Send" to "Rest Day." Coaches see who's recovered and who's not.
Predict race finish times from training splits. Compare station times to gym averages. Athletes see exactly where to focus to shave minutes off their HYROX time.
Athletes and station cameras capture movement clips automatically during training. On-device pose detection flags depth, range, and bar-path issues per station. Coach reviews flagged clips first instead of watching every rep.
Live circuit timer with team cards, partner rotation, and station tracking. Real-time broadcast to all athlete devices. Built for class-style HYROX training.
Built fast, shipping weekly, validated with real coaches and athletes.
Designed for scale from day one. Zero infrastructure cost at current usage.
