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 running analytics for runners who take their data seriously. No subscription. No account. No compromises. READINESS FIRST. THEN THE RUN. Your Readiness Score tells you in the morning how much load you can handle today. One number, one orb, one clear recommendation. Calculated from HRV, resting heart rate, sleep, and your training load. No gut feeling. MILES ALONE SAY LITTLE. Ten easy miles and ten at tempo are not the same session. Runnerd turns every run into training load, from duration and heart rate. Plus heart rate zones and your intensity mix by 80/20. YOUR PLAN, ALL THE WAY TO RACE DAY. A season timeline instead of loose training days. Phases, weekly volume, race goals. You create planned runs right on the iPhone, and the coach suggests one and fills in the fields. Three coach characters judge the same day: The Ambitious One, The Balanced One, The Patient One. You pick the tone. FOR NERDS. WHO RUN. The Analysis tab breaks down your running economy: running power, aerobic efficiency, cadence, ground contact time, TRIMP. Trend lines show where you are heading across three months, six months, or a year. Every technical term is explained. RUNNERD DOESN’T RECORD RUNS. IT READS APPLE HEALTH. The recording is done by your Apple Watch, your iPhone, or any app that writes to Health. Runnerd reads what is already there. No Runnerd server, no login, no sign-up. Syncing runs through your private iCloud. Nothing lands on anyone else’s servers, nothing gets sold. FIT IS NOT FRESH. RUNNERD KNOWS. The Performance Management Chart shows fitness, fatigue, and form across your entire history (CTL, ATL, TSB). Fit and fresh are two different numbers, and only together do they tell you when a race will land. Plus race predictions from 5K to marathon. AFTER THE RUN IS WHEN IT STARTS. Every run with map, splits, heart rate zones, pace, and elevation profile. Runnerd classifies seven run types on its own. You mark the race yourself. AND THE DETAILS ONLY RUNNERS NOTICE. Shoe mileage with a wear limit. Personal bests, found in your own runs. Running partners. The shape of your week. No separate view, no big deal. Just there, because it belongs. PRO? ONCE. BOTH DEVICES, FOREVER. Runnerd is free and stays free. Pro unlocks the full analysis depth: running form analysis, race predictions, the coach “The Ambitious One”. Buy once, use it on iPhone and Mac. No subscription. Ever. NO AI. SPORTS SCIENCE INSTEAD. Runnerd calculates with the Banister model, with Daniels’ VDOT, and with the Karvonen formula. Methods from training science, not from marketing. Every number can be explained, every value has a source. You can do the math yourself. The coach texts are not AI either. The sentences are written by hand, and your own numbers decide which one appears. Sometimes one repeats.
