What the app does
It does not just show numbers. It explains them.
Apple Watch records the workout. SwimGlass extracts the signals swimmers need before deciding what to do next.
A decision right after opening.
Latest swim, 30-day performance, and pace mix against reference without spreadsheets.
Every swim has context.
Filter 30/90 days or all workouts, then compare distance, pace, heart rate, calories, and coach notes.
Active pace separated from rest.
Workout detail uses active segments, pace zones, stroke styles, route maps, and reference comparison.
Trends become the next step.
Training load, consistency, anomalies, pace projection, and data quality in one calm view.

FAQ
Before downloading.
Does SwimGlass write data to Apple Health?
No. The app uses HealthKit permissions only to read swimming workouts and available metrics.
Do I need Apple Watch?
SwimGlass analyzes data stored in Apple Health, most often from Apple Watch pool swim or open-water workouts.
Why are heart rate or map sometimes missing?
HealthKit does not include every sample for every workout. SwimGlass only shows data that is available.
