Boulder Tracker and climbing tracker (indoor)
· v3.1.262
About
Boulder Tracker is an indoor bouldering and climbing session tracker for your Garmin watch. It counts your boulders and routes, auto-detects falls, and lets you log climbs with one button press - paired with a powerful free companion web app for live view, charts, history, personal records and trends. (The automatic HR-based counting is marked as a beta feature, as it is still experimental.)

IMPORTANT: The menu must open on a long button press. On most watches it's the lower right (lap/back) button.
HOW IT WORKS
The primary counting flow is reliable and simple:
- Fall/drop detection (automatic) - accelerometer freefall + impact analysis adds a boulder for every detected fall.
- Manual logging (one button) - press SELECT after topping a route. Double-tap within 350 ms to undo.
Additionally, an experimental HR-based auto-detection state machine (IDLE to CLIMBING to REST) is available as a BETA feature. It is OFF by default - enable it from the long-press menu ("Auto-Count: ON (BETA)"). With Auto-Count on, an in-session carousel page toggles two detection phases: High-frequency for dense climbing (warmup/circuits) auto-counts with a refractory learned from your own cadence, while Max-intensity for projecting turns auto-count off so you log each hard send by hand. HR-based detection works best with a stable optical heart rate sensor or a chest strap; we keep tuning it across firmware versions and body types.

ACCURACY NOTE
We are honest about what is reliable and what is still being tuned. Fall detection and manual logging are accurate. HR-based auto-detection is a BETA experiment - useful, but it may miss short routes or trigger on cardio between climbs. The session fingerprint is also a BETA visualization. The watch always shows you the totals so you can verify and undo with a double-tap.
GRADE LOGGING & TOUCH
Optional per-climb grade logging uses the touchscreen. On Fenix, Forerunner and Epix watches the touchscreen is off during activities by default - enable Touch during activities in the watch's system settings to use grade logging while recording. Boulder counting, fall detection and live sync work on every supported watch regardless.
What's new
What's new in this release:
- Ending a session by tapping now works. On touch watches the paused screen's
"End" control resumed the session instead of ending it; tapping the lower half
now really ends and saves the session
- The paused screen now says it can be tapped - upper half resumes, lower half
ends (touch watches only)
- Pressing the menu button on a paused session now opens the session menu, with
Resume and End Session, instead of the settings menu that offered no way out
- New weekly streak, "Keep the week", on the glance, the end-of-session screen
and the Consistency page. Forgiving by design: a missed week simply starts
again at Week 1 - never a "streak lost"
- The app icon no longer carries a BETA badge
- Also includes the two crash fixes from the previous release: an invalid value
written at the end of an activity, and a "too many timers" error behind the
achievement banner
