StairSprint

StairSprint turns any staircase into a training tool. Press LAP at the bottom, sprint, press LAP at the top — the app records each climb with its time, your heart rate, and computes your vertical power in watts per kilo (W/kg), the number that makes efforts comparable across any staircase in the world. ON THE WATCH • One-button lap workflow built for stair repeats — no fiddling mid-session • Set your staircase once (step count, step height, 1-step or 2-step cadence) and it sticks for next time • Live screen: current climb time, climb count, heart rate • Per-climb summary table at the end: every rep's time, W/kg and HR • Weighted-vest support — add the load, W/kg accounts for it • Records a standard FIT activity that syncs to Garmin Connect like any workout THE COMPANION SITE (optional, free) stairsprint.baselinetech.ie — a crowdsourced world map of trainable staircases. Import your workouts, see your W/kg trend, and race everyone else's times on your local steps. Find a famous staircase (Manitou Incline, Montmartre, the 1000 Steps...) or add your own to the map. No subscription, no ads.

Sessions uploaded directly to StairSprint now include the calories burned, so the web app shows kcal alongside heart rate and power for every workout
