Splits vs Runnerd

Every run is read automatically - easy, tempo, intervals, long, race - and cross-referenced with your heart rate, VO₂max, sleep and the weather, so you see what your training is doing to your body, not just what you did. 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 Turn photos taken mid-run into share cards with your route and stats overlaid - story-ready in two taps. 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.

Runnerd is a running coach and a serious analytics app in one. It builds a plan around your goal, explains every recommendation and works with the runs you've already logged. No subscription. No account. No compromises. HOW IT WORKS Connect Apple Health and Runnerd reads your past runs, whether they came from your Apple Watch, your iPhone or another running app. No blank slate: Runnerd knows where you stand from day one. Keep tracking with whatever you use today. Set a goal, like your next half marathon, and pick a coach. The Patient One builds up carefully, The Ambitious One pushes harder, and The Balanced One sits in between. The difference shows up in your plan, not just in the tone. Runnerd maps out every week until race day and schedules more of the run types you enjoy. You can add your own runs whenever you like. Each morning, your coach checks the plan against your readiness. After each run, it reviews how it went. Ahead of your goal? It'll tell you. Goal asking for more than your coach allows? It'll tell you that too. FOR NERDS WHO RUN Fitness, fatigue and form, running economy, intensity, training load: Runnerd shows whether your training is working and explains every term along the way. It's all built on proven sports science, not AI: Banister for fitness and form, Daniels VDOT for training paces and predictions, Karvonen for heart rate zones. IPHONE AND MAC Check in on your iPhone, dig deeper on your Mac with a native Mac app. Your data syncs through your private iCloud. Runnerd collects nothing and runs no servers.
