## What is TraceLens?

TraceLens turns the workouts already stored in Apple Health into insights you can actually use — no social feed, no leaderboards, no accounts.

YOUR WORKOUTS, FINALLY UNDERSTOOD
Every run, ride, walk and hike you've recorded lives in Apple Health. TraceLens reads that data — routes, pace, heart rate, elevation — and gives it a clear, calm place to live. See your timeline, tap any workout, and dig into what happened and why.

ROUTES THAT TELL STORIES
Open any workout to see its route on a map, with pace, heart rate and elevation curves you can scrub. Drag the cursor and watch the map follow — find the exact moment that hill broke your pace.

COMPARE WITHOUT THE ANXIETY
Select two or three workouts and compare distance, time, pace, heart rate, ascent side by side — with weather context and honest notes. No leaderboards. No competition. Just you vs. you.

TRENDS THAT SHOW PROGRESS
Weekly, monthly and yearly summaries reveal whether you're training enough and getting faster. Distance bars, pace trends and period-over-period changes at a glance.

YOUR DATA, YOURS ONLY
TraceLens is a personal tool. Everything is read from Apple Health and analyzed on your device. No account, no cloud sync, no ads, no tracking.

Every route tells a story. Find yours with TraceLens.
