GoSki - Ski Tracker

Precision ski telemetry for serious riders. 1Hz GPS, vertical drop, speed profile, run classification and resort data. All on-device, no subscription.

GoSki is a precision ski telemetry and resort intelligence tool designed for skiers and snowboarders who want data, not guesswork.

HIGH-PRECISION TRACKING • 1 Hz GPS sampling with full accuracy metadata • Computed metrics: top speed, average speed, vertical drop, distance, run count • Automatic activity classification distinguishes ski runs from chairlift rides • Background location support — tracking continues even when the screen is off • Works fully offline; all data written locally via SwiftData

POST-RUN ANALYTICS • Charts for speed over time and altitude over time • Per-run statistics: duration, max speed, vertical loss, total distance • Season trends: aggregate vertical, total runs, fastest day • Native SwiftUI charts optimized for iPhone displays

RESORT INTELLIGENCE • Curated resort database covering global destinations • Trail counts broken down by difficulty (green / blue / black / double black) • Elevation profile: base, summit, vertical drop • Live weather integrated via Open-Meteo (air temperature, wind, snowfall) • Interactive map with search, filter and sort

PRIVACY ARCHITECTURE • All tracks, runs and analytics stored locally on your iPhone • No accounts, no login, no ads, no analytics SDK • The only outbound request is to the public Open-Meteo weather API; no personal data is transmitted • Clear permission prompts, location access requested only when needed

OPTIMIZED FOR iOS • SwiftUI + SwiftData, native performance • iPhone-only, portrait and landscape supported • Background modes limited to location, activated only during active tracking • MapKit powered resort and track visualization

No subscription. No data harvesting. Just a professional tool for skiers.
