Pace Radar vs Runnerd

Pace Radar reveals what other running apps miss: how your heart responds to the same pace over time. A downward trend means real aerobic progress — not just faster splits. YOUR HEART TELLS THE REAL STORY Every run is parsed second-by-second. Pace Radar aligns your heart rate and pace data on a precision grid, groups them into pace buckets, and plots weekly trends. Watch your heart rate drop at the same effort — that's fitness you can see. • Trend charts that show heart rate by pace bucket, week by week • Configurable pace buckets (15s to 90s width) for your training style • Rolling averages that smooth noise and reveal real progress • Time ranges from 1 week to 5 years of training history EVERY RUN, ANALYZED Tap any workout for a full breakdown: • Dual-axis chart: pace and heart rate over time, side by side • Per-kilometer splits with pace bars and heart rate • Cardiac decoupling analysis — see if your heart rate drifts during long runs • Actionable insight cards that explain what the numbers mean GRADE-ADJUSTED PACE Hills don't lie, but flat pace does. Pace Radar adjusts your pace for elevation changes using the Minetti metabolic cost model, so your trend data reflects true effort — not just terrain. EFFICIENCY FACTOR For Apple Watch runners with power data: track your Power-to-HR ratio over time. A rising efficiency factor means you're producing more speed per heartbeat. CARDIAC DECOUPLING The metric elite coaches use. Pace Radar compares your heart rate in the first and second half of each run. Under 5%? Strong aerobic base. Over 10%? Time to dial it back. Color-coded status on every workout and in your trend summary. PERSONALIZED INSIGHTS Pace Radar reads your training patterns and generates specific observations: "Your heart rate at 5:30 pace has dropped 4 bpm in 12 weeks." Real data, not generic tips.

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.
