Take control of your running gear with TreadLeft. TreadLeft connects directly to Strava and Apple Health to automate your shoe tracking. No more manual logs or guessing games—know exactly how many miles are on every pair in your rotation, how your gear is performing, and precisely when it’s time to retire them. KEY FEATURES: Seamless Activity Syncing: Connect Strava and Apple Health to import your runs instantly. We automatically match activities to your active rotation, so your dashboard is always up to date. Tactical Shoe Loadout: Build your ultimate arsenal. Assign distinct roles to your shoes (Daily Trainer, Race Day, Trail, Recovery) and monitor the health of each category at a glance to ensure your rotation is perfectly balanced. Visual Wear Tracking: See the health of your gear instantly. Colour-coded progress bars (Fresh, Worn, Critical) help you visualise wear, protect your joints from dead foam, and prevent injury. The Finishers: Every shoe has a lifespan. When it's time to put a pair out to pasture, send them to the Finishers to preserve their lifetime stats and share a custom retirement card on your feed. Advanced Analytics: Deep dive into your data. Dedicated Performance and Gear tabs show your weekly mileage trends, wear rates, and total distance across your entire inventory. Live Shoe Deals: See the best prices on the exact models you need from major retailers, updated in real time. Set a price alert, and we'll notify you the moment your shoe drops below your target—so you never miss a flash sale. Smart Dashboard: Your running command centre surfaces exactly what needs attention—unassigned runs, critical wear alerts, rest-day reminders, and automated retirement countdowns based on your actual weekly pace.

The coach that tells you why. Every plan app adjusts. Treadly is the running coach that tells you why each run is there, puts every change to you before it makes it, and keeps a record of how its calls held up. The way a human coach would, on your iPhone and Apple Watch. Every run has a reason. Today's run says why it exists. Trimmed to 4.2 miles at readiness 36. Eased twenty seconds a mile for the heat. Every number that comes from the research opens to the paper behind it, and the week header shows the climb cap out loud. Readiness comes from your sleep, HRV, and resting heart rate in Apple Health. Coach calls. A bad night, a heat wave, a missed run, a sore knee. The coach proposes a change and waits. Accept or undo. Hurt, sick, or life keeps your streak safe. If a change would be too small to notice, it does not ask at all. A coach on the record. Every call and your answer go on the record. "You took the ease-day call 8 times. Next runs averaged B+." Called vs ran grades the coach's own pace calls against what you ran. Your race confidence comes with a finish window that narrows as race day nears, and locks two weeks out so you cannot cram. Someone can see your run. Free. Add up to three safety contacts. When you run, they can follow a live page that opens in any browser, no app and no account. Slide for SOS on your phone, your watch, or the Lock Screen and they hear first, with your location and your local emergency number one tap away. If your phone goes silent, they get a text, and one more when you are back. On race day, make a link from your race letter and send it to anyone: they see where you are on the course and your projected finish. The run itself. Treadly records the run, on your watch or just your phone. Two real voices in your ear, never a robot. Pace and heart-rate zones on your wrist, reps counted as you run them, and auto-pause that waits for you. If you live on Strava, Garmin, or COROS, connect once and it all flows in. Plans for any race. 5K to marathon, from your pace today. Compare coaching approaches with real numbers before you commit. Strength days live on the plan too, timed from your wrist. New to running? Your first month on the ladder is free. Shoes, free forever. Every pair gets a role. Treadly spreads the miles so shoes wear out on schedule instead of by surprise, and tells you when one is done. Run with people. Send a run to a friend and it lands on both plans, your long run included. They get two weeks of Pro when they join. Pair with one partner who sees the shape of your week and hears when a run goes by. What is free, what is Pro. Shoes, readiness, the science library, and safety contacts are free. The coach's calls, the record, inviting a friend, and a partner are Pro, after a 14-day trial that starts with your first run. $9.99 a month or $59.99 a year. Treadly depends on your phone's signal and battery and is not a substitute for emergency services. Coaching is grounded in published training science and is not medical advice.
