About
AX Core is your training operating system — one dashboard that brings together your lifting, recovery, sleep and nutrition. No more juggling four apps to understand whether today is a push day or a pull-back day.
WHY AX CORE IS DIFFERENT
Most workout trackers log your sets and stop there. AX Core combines your training with the data that actually predicts how hard you should push: HRV, sleep quality, resting heart rate, recovery score, and daily nutrition — all in one Today dashboard. Connect Apple Health and WHOOP to bring everything together automatically.
TRAIN WITH STRUCTURE
Follow expert-built programmes across strength, hypertrophy and HIIT — or build your own from scratch. Barbell, kettlebell and dumbbell programmes designed to progressively challenge you week after week. Pro users unlock an exclusive library of premium workouts, ready to go whenever you are.
TRACK EVERY REP
Log workouts with full set-by-set tracking, break personal records, and analyse your training volume over time. Live Activities keep your current set live on the Lock Screen and Dynamic Island — no more pulling your phone out between sets.
KNOW YOUR READINESS
Daily readiness scoring tells you when to push hard and when to back off. HRV trends, sleep breakdown, active calories and nutrition macros — all in one place, updated automatically from Apple Health.
COMPETE WITH RIVALS
Connect with AX Rivals — the companion app that lets you challenge friends, training partners, and gym rivals to head-to-head fitness battles. Deep link straight from your AX Core workout into a live challenge.
STAY ON STREAK
Your home screen widget keeps your training streak front and centre — because consistency is the only programme that actually works.
AX CORE PRO
Unlock unlimited programmes, full training history, advanced analytics, CSV data export, and the complete Pro workout library. AX Rivals subscribers get an exclusive discounted rate.
Log every rep. Beat every session.

They can import it free. Cardio that makes sense — running and other cardio now log by time instead of sets and reps. Smoother Live Activity — the workout timer on your Lock Screen and Dynamic Island now displays cleanly.
