- Read-only HealthKit
Read-only HealthKit. No writing to Apple Health.
Long-term progress is readable in the app
After a swim, questions remain
You have the data. Often not the context.
Apple Health stores the workout. A swimmer still needs to see pace, volume, available metrics, and whether a session was a one-off variation or part of a longer trend.
What happened to pace?
Workout detail shows available metrics and comparison against your 90-day average.
Was it a one-off or a trend?
Trends, load, and consistency help separate one different session from a longer rhythm change.
What deserves attention?
Insights highlight available signals, anomalies, and data quality without coaching promises.
From recording to context
SwimGlass is not another logbook. It interprets your swimming.
The app reads existing HealthKit workouts and turns them into clear metrics, trends, and insights without manual copying.
First, it turns a workout into a readable swim.
Distance, pace, heart rate, energy, stroke count, and other available HealthKit metrics are kept together.
Then it compares the session with recent weeks.
Key metrics get a 30/90-day reference, so one session does not stand alone.
It shows what HealthKit actually contains.
Maps appear only for open-water workouts with route data, and missing metrics are not treated as certainty.
Trends become things worth watching.
Load, consistency, anomalies, pace projection, and data quality help you read progress without medical or coaching promises.

FAQ
Before downloading.
Do I need Apple Watch?
SwimGlass analyzes swimming data stored in Apple Health, most often from Apple Watch pool swim or open-water workouts.
Will it work with older swims?
Yes, if those swimming workouts are stored in Apple Health and contain metrics the app can read.
Why are heart rate or map sometimes missing?
HealthKit does not include every sample for every workout. SwimGlass only shows available data and makes missing data visible.
Does SwimGlass send my Health data to a server?
The documentation describes SwimGlass as a local analytics view over Apple Health data, not another cloud layer over health data.
