RunNerd reads the runs you've already done and tells you what they mean. Same pace, lower heart rate. Faster, but working harder. Cadence slipping on the long ones. The things your numbers say when someone actually reads them. KNOW WHY EVERY RUN FELT THE WAY IT DID Every run gets a name, a read, and a receipt. Two short paragraphs from the coach on what happened and why, then elevation and pace on one chart with your heart-rate zones coloured along the hill. Tap a mile to see what it cost you. A PLAN FOR YOUR RACE DATE Tell the coach the race and the date. The plan builds around it, reads every run you finish, and adjusts the next one. Move a run, your plan adjusts. PRs WITH THE WHY A new personal record shows the old mark, how long it took, and what changed: heart rate at pace, cadence, conditions. Not just a time. YOUR WEEK AND MONTH, THE MORNING AFTER Weekly and monthly recaps on Home: miles, adherence, your best efforts, and one line on what the data says. Share any of it as a clean image. ASK ANYTHING A coach you can talk to. Why last week felt hard, what to do on today's run, whether you're on track for the race. WORKS WITH YOUR GEAR Apple Watch, Garmin, intervals.icu, and anything that writes to Apple Health. Your running history comes with you. NEW TO RUNNING? Pick a first goal, run your first mile or your first 5K, and let your phone guide the run out loud with run/walk intervals. No watch required. WHAT YOU GET - Named runs with a plain-English read on each one - Elevation and pace on one chart, heart-rate zones included - Personal records with what changed since the last one - Weekly and monthly recaps - Shareable receipts for runs, PRs and recaps - Race plans that adapt week to week - Easy, interval, long, and run/walk workouts - Guided runs with spoken cues - Weather-aware run recommendations Built by a lifter who became a runner and got tired of staring at numbers that didn't explain anything.
