PaceLensSee how your running is changing.
PaceLens turns the runs already in the Health app into a clear view of your progress, with focused trends, individual runs, and records—privately on your iPhone.
No account
Open PaceLens and review your own training history.
Processed on iPhone
Your running analysis stays on your device.
Progress Story
The change that matters, before the metric grid.
PaceLens opens with your runs and distance for the selected period, then compares them with the previous one when enough data exists. It is factual, filter-aware, and easy to scan.
Focused trends
Three charts. Each one explains what it shows.
Follow pace, training volume, and cardio fitness without smoothing, predictions, or invented scores.
Average pace
One point per eligible run, with exact values and a clear reminder that lower pace is faster.
Weekly distance
Recorded distance grouped by calendar week, including clearly identified partial weeks.
VO₂ max
Actual cardio-fitness estimates from the Health app, shown over time when available.
Built around runner jobs
Understand. Inspect. Remember.
The app’s four native tabs keep each task predictable while one shared filter controls every data view.
Progress
Understand how your training is changing through a concise story, three trends, supporting metrics, and heart-rate zones.
Runs
Find a workout in the filtered monthly history and open its existing distance, duration, zone, and record context.
Records
Keep personal records, milestones, consistency, and streaks in sight for the exact scope you selected.
Your view, your data
Depth when you need it. Quiet when you do not.
Filters across every view
Choose recent periods, calendar ranges, the last runs, or indoor and outdoor scopes without losing the selection between launches.
Heart-rate zones with context
Review duration and distance by your configured zones, including unzoned time when the data exists.
CSV export only when you choose
Create the current filtered export locally and share it through the iOS share sheet you select.
Private by design
Your training does not need another account.
The PaceLens app has no backend, cloud sync, analytics, tracking, or social feed. It reads compatible running data only after your Health permission and processes it on your iPhone.
