IMPORTANT — to see your results: open stairsprint.baselinetech.ie/watch on your phone and enter the Link code shown on the watch. Your sessions are already uploaded and waiting for you. 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.

Touch is locked while recording, so rain or a sleeve on the screen can't mark a lap or open a menu. Lap and Stop are buttons only. START resets the stair count in the picker, so switching staircases is quick. Short flights now count: climbs from 2 seconds up are scored (was 5). Live W/kg from the barometer and GPS staircase auto-labels.
