Gear-Life uses patent-pending wear intelligence across three distinct gear categories to track how each piece of gear actually degrades. Not just how far it's gone.
Foam-Based Gear
Foam Wear
Goes beyond mileage. Every session is scored on how hard it actually was on your foam, not just how far you went, so two runs of the same distance can wear very differently.
- Running shoes
- Walking & hiking shoes
- HIIT & CrossFit shoes
- Lifting shoes
- Insoles
Mechanical Components
Component Wear
Tracks mechanical degradation for rigid gear. Each bike component ages on its own timeline, and cycling shoes are assessed across multiple dimensions, so you always know what needs attention next.
- Bikes, tracked by component
- Cycling shoes, tracked across multiple health dimensions
Time & Use-Based Gear
Time-Based Wear
Tracks gear that degrades with time and use, not mileage, helmets, compression gear, and more, each on its own timeline.
- Helmets, with impact event logging
- Running vests
- Compression gear
- Hiking poles
- Orthotics
Gear-Life is built Apple Health first: every workout logged by your iPhone, Apple Watch, or any app that syncs to Health, Hevy, Strong, Garmin, and more, already works, automatically. Ultrahuman is our premier ring partnership on top of that foundation. Runners, walkers, hikers, cyclists, and gym athletes all covered.
👟
Foam Wear Tracking
Foam degradation calculated from every workout, not just the mile. Know your shoe health to the percent.
🚴
Cycling Gear
Track bikes by component (chain, tires, brakes, cassette, bar tape) and cycling shoes by cleat and closure health. Wear surfaces before you feel it.
🪖
Other Gear
Running vests, hiking poles, helmets, compression gear, and orthotics, all tracked on their own timeline. Log impacts, wash cycles, and tip miles.
🔄
Smart Rotation
Wear Today recommendations based on foam health, recovery score, and activity type. Quiver Optimizer shows which gear is over-rotated and which is idle.
💜
Recovery Intelligence
Sleep score, HRV, resting HR, VO2 Max, REM & deep sleep breakdown, skin temperature, and Movement Index power daily recovery scoring and Total Daily Load. 7-day dual HR and HRV trend charts with tap-to-reveal tooltips and training load context.
🔔
Proactive Alerts
Foam health warnings, component wear alerts, time-based replacement reminders, post-workout shoe confirmations, and heat advisories: all before you feel the impact.
💍
Ultrahuman Ring
Our premier third-party partnership. Recovery Index, HRV, sleep stages, skin temperature, Movement Index, and VO2 Max feed directly into Sage's daily recommendations, layered on top of Apple Health as the foundation every workout app already writes to.
👜
Insole Tracking
Track aftermarket insoles separately. Swap them between shoes and watch their mileage follow. One insole library, any shoe.
📓
Gear Diary
A photo timeline for every piece of gear. Log notes, milestone moments, and memorable sessions. 100-mile milestone prompts built in.
🎙️
Siri Shortcuts
"How's my chain?" "How are my running shoes doing?" 14 Siri intents covering foam health, component alerts, recovery, and rotation.
📊
Performance Intelligence
HR zone breakdown per shoe, weekly effort summary, and activity type charts, so you understand how each gear category affects your training.
📱
Widgets & Watch
Home screen widgets, lock screen complications, and Apple Watch support. Rotation Roulette widget picks today's shoe when you can't decide.
