Health & Performance Analytics for Busy People
JackStack helps individuals turn their Garmin health and activity data into clear, actionable insights—so they can better understand how sleep, stress, and training affect daily performance and long-term well-being.
Private beta • Founder-led • Data-firstWhat JackStack Does
JackStack securely connects to your Garmin account (with your permission) and organizes key metrics—sleep, heart rate, training load, steps, stress, and more— into simple dashboards and trends. The goal is to make it easier to see patterns over time: what helps, what hurts, and where to adjust.
Unified View
Bring together activities and all-day metrics from Garmin into one place for a clearer picture of your health and training.
Trends Over Time
See how sleep, stress, and training load evolve across days, weeks, and months—beyond individual workouts.
Privacy by Design
Your data stays yours. JackStack does not sell user data and keeps access limited only to what you authorize through Garmin Connect. You can revoke access at any time.
Who JackStack Is For
JackStack is currently in a small private beta, focused on people who use Garmin devices and want a deeper understanding of how their habits and training choices influence energy, focus, and recovery.
Looking ahead, JackStack may offer optional group-level insights for teams or communities—always with strict privacy protections and without sharing individual user data.
