Something hurts, and every other running app will still cheerfully hand you a tempo session. ZeeRun asks where it hurts, how bad it is, and whether it gets worse or better as you run — then tells you whether to run, modify or stop, and what it takes to get back. THE NIGGLE ROOM Tap the spot on an anatomical body map: shin, calf, achilles, knee, hip, foot, hamstring, groin, IT band, back — each side tracked separately, so a left achilles and a right knee are two different stories. Then answer three quick questions. Get a plain-language run, modify or stop verdict, with the reason behind it and the red flags that mean see a clinician, not an app. Anything worse than a watch-list ache opens a return-to-run ladder: four rungs from walk-jog back to a full session, each with a pass condition you clear before the next unlocks. The ladder is free, and your plan must respect the rung you are on — it cannot serve you a tempo on rung one. THE MORNING READ Four taps each morning become one readiness score, pulled from your sleep, HRV and resting heart rate against your own baseline through Apple Health. That score sets today's session and the week's mileage ceiling before you lace up. Ask Siri for it without opening the app. YOUR DURABILITY A durability score built from your injury history sets a weekly mileage ceiling and names the sites most worth watching. Load ratio and repair reading compare your last 7 days against the 4-week base you have truly adapted to, so ambition doesn't outrun adaptation. The strength work it keeps naming is now a guided prehab routine built around your own weak points. THE RUNNING Live pace, mile splits, saved routes, a Home Screen widget and a Live Activity. Intervals are called rep by rep in your ear, and every rep is saved as its own split. A cadence read draws your stride against your own average, never a magic number, with an optional metronome. A weather card reads heat, humidity, wind, air quality and daylight into one run-safety verdict, with what to wear. SHOES AND FUEL Give each pair a job — daily, tempo, long, race or trail — and ZeeRun puts the right shoe forward, retires it on the mileage that job deserves, and shows how your last four weeks split across the rotation. Long runs and races get a fuelling timeline: what to take and when, scaled to the heat. COACH Z An on-device coach voice writes your morning brief, your weekly debrief, and the Sunday Edition — a shareable newspaper front page of your running week — explaining every verdict without hype or noise. Nothing about your training leaves the phone. No account, no cloud, no ads reading your health data. ZeeRun is a wellness tool built to help you train longer by training smarter, not a medical service — for medical concerns, see a professional. FREE FOREVER The daily check-in, today's read, Coach Z's verdict, the body map, the niggle verdict, the return-to-run ladder, Siri, shoe rotation, fuelling, prehab, and all your logging — runs, routes, shoes, records, races and Mind tools. No account, no card.
