No account. No server. All analysis runs on your iPhone from your Apple Health and Apple Watch data.
WHAT SPLITS READS FROM YOUR RUNS
• Automatic run classification - every run typed from its heart-rate shape and pacing, honestly, with a confidence level you can audit
• Proof of fitness - the same pace costing your heart fewer beats per minute than it did months ago, measured, not vibes
• Heart rate zones built from your own recorded maximums, not a formula guess
• Your response curve - which training actually moves your VO₂max, resting heart rate and HRV in the weeks that follow, tested across response windows from 2 to 12 weeks
• Heat sensitivity - your personal pace cost per degree, from watch-recorded conditions
• Smooth pace, effort and elevation charts with detail you can pan through on long runs
• Your journey - milestones, achievements and personal records across your entire history
SHARE THE RUNS WORTH SHARING

PRIVATE BY DESIGN
Your runs never leave your phone. Splits has no account system, no cloud, no ads and no tracking. It reads Apple Health with your permission and does every calculation on-device.
FREE AND PRO
Your latest run is always free, fully analysed. Splits Pro unlocks your full history, journey, achievements and the deep analysis - with a 7-day free trial on the monthly plan. Cancel anytime in Settings.
Splits works with running workouts recorded by Apple Watch or any app that saves runs to Apple Health. The more history you have, the more it can tell you - your first import reads years of runs in minutes.
