Tread: Shoe Mileage Tracker

Running shoes wear out long before they look worn out. Tread keeps an honest count of the miles on every pair you own, so you know when it’s time for new ones — and which pair to grab today. Run, walk or hike with your Apple Watch or iPhone like you always do. Tread reads the workout from Apple Health and asks one question: which shoes? Tap your usual pair from the notification, the app or your wrist, and the miles land where they belong. WHEN TO RETIRE Set a retire-at limit for each pair. Tread watches your real weekly miles and forecasts the week each pair will reach it, warns you at 90%, and moves retired shoes into a searchable history with their final miles and cost per mile. BUILT FOR A ROTATION • Your usual pair is picked for you, per workout type • Auto-assign runs to one pair and walks to another • Split one workout between two or more pairs • Up next suggests the pair that has rested the longest • Cost per mile, average pace and weekly bars for every pair EVERY WORKOUT THAT WEARS SHOES Outdoor and treadmill runs, walks, hikes, trail runs, stairs and elliptical sessions are all counted. Bike rides and swims are left out. MAKE IT YOURS Snap a photo of your shoes and Tread lifts them into a sticker with a white outline, right on your iPhone. Scan the box barcode to fill in the brand and model. ON YOUR WRIST AND HOME SCREEN • Apple Watch app with a post-workout prompt and complications • Home Screen and Lock Screen widgets • Workouts and Shoes side by side on iPhone Duo PRIVATE BY DESIGN No account. No ads. No tracking. Your data stays in Apple Health and your own iCloud, and syncs between your iPhone and Apple Watch. Tread only reads from Health; it never writes. Everything works offline except the optional barcode lookup. One purchase. No subscription.
