About

Garmin Connect shows max HR and average HR per lap — but never the minimum. If you're doing interval training and want to
  see how far your heart rate drops during recovery laps, there's no built-in way to get that.

  Garmin Lap Analyzer fills that gap. When viewing any activity on Garmin Connect, a "Lap Stats" button appears. Click it to:

  - Select which laps to analyze
  - See min HR, max HR, and avg HR computed from raw per-second measurements
  - See avg pace and distance per lap
  - Copy the results as a clean, plain-text table

  How it works:
  The extension reads the raw FIT file (per-second recording data) directly from Garmin's servers using your active session —
   no passwords or tokens are stored. All processing happens locally in your browser.

  Example output:

  Lap | Distance | Avg Pace | Min HR | Max HR | Avg HR
  1 | 1.00 km | 5:15/km | 120 | 162 | 145
  2 | 1.00 km | 5:08/km | 130 | 168 | 152
  3 | 1.00 km | 5:02/km | 128 | 175 | 155

  Privacy:
  - No external servers — all data stays in your browser
  - No stored credentials
  - No tracking, no analytics, no telemetry
  - Only activates on connect.garmin.com
