Each sport. The numbers it actually needs.
No generic step counts. Each sport gets the load model coaches already use, computed from what you log and what Apple Health already knows.

Log the set. Beat the last one.
Every set shows what you did last time. Rest timers run on the sheet. PRs are detected as they happen, not entered later.

Fuel tracked against the training, not in a vacuum.
Daily macro and hydration targets, food search, barcode scan, saved meals. A weekly AI summary reads your nutrition against your training load and says what it sees.

Fitness, fatigue and form on one chart.
Every session gets a Training Stress Score. The Performance Management Chart plots chronic load, acute load and balance, and the coaching insights say what the trend means for this week.
Live endurance sessions on the wrist. Structured workouts arrive step by step, with targets.
HRV, resting heart rate and sleep from Apple Health. Per-muscle fatigue with overlap warnings before you double up.
Build multi-week programmes with progression rules, or run one written by a coach on the marketplace.
Body composition photos and measurements, plotted over time.
A daily readiness indicator from grip strength.
Follow other athletes, give kudos, keep a feed that is about the training.
The stack a serious athlete ends up paying for.
Five tools, five logins, five places the data never quite meets. PROTR covers all of them in one place.
Is PROTR free?
Yes. All core features - workout logging, nutrition tracking, AI insights, and the marketplace - are free. There are no paywalled essentials.
What sports does PROTR support?
Running, cycling, swimming, triathlon, strength training, Hyrox, functional fitness, yoga, pilates, and recovery sessions.
Does PROTR work with Apple Watch?
Yes. The PROTR Watch app lets you log workouts and track endurance sessions from your wrist, syncing everything back to your iPhone.
Can I track my training load like a pro?
Absolutely. PROTR calculates Training Stress Score (TSS) for every session and plots your Chronic Training Load (fitness), Acute Training Load (fatigue), and Training Stress Balance (form) on a Performance Management Chart.
Does it sync with HealthKit?
Yes. PROTR reads sleep, HRV, heart rate, and VO2 Max from Apple Health, and writes workout and nutrition data back so everything stays in sync.
Free to plan. Free to log. Free to analyse.
The marketplace is there for when you want a real coach looking at the numbers.
