Yes — your data is secure. All your data is stored on your device. Activity data syncs via Apple CloudKit/HealthKit when enabled. We don't use third-party cloud services, analytics, or tracking of any kind. Your activities, routes, and health data are protected by Apple's privacy standards. See our Privacy Policy for full details.
Yes! Trekka tracks activities completely offline. You can download map regions for offline use, so you can navigate even without cellular service. GPS tracking works anywhere you have a clear view of the sky. No internet connection required for any tracking features.
Yes! The watchOS app is fully standalone. You can track activities, view maps, navigate routes, and monitor all metrics directly from your Apple Watch — no iPhone needed. The iPhone companion app provides activity history, route management, settings sync, and workout mirroring.
Yes! Trekka integrates with Apple HealthKit to read heart rate and other health metrics during workouts, and write your workout data back to Apple Health so it contributes to your Fitness rings. This integration is optional and requires your explicit permission. You can revoke access at any time in iOS Settings > Privacy & Security > Health.
Trekka supports 20+ activity types including hiking, trail running, walking, running, mountain biking, road cycling, gravel biking, climbing, mountaineering, kayaking, canoeing, stand-up paddling, skiing, snowboarding, backcountry skiing, cross-country skiing, snowshoeing, and more. Each activity type can have its own customized data field layout.
Trekka uses advanced GPS filtering algorithms similar to Apple's own apps, eliminating jitter for rock-solid tracking even under tree cover. With the barometric altimeter, elevation accuracy is sub-meter. Horizontal GPS accuracy typically ranges from 3–10 meters depending on signal strength. You can enable Precise GPS mode for maximum accuracy (at the cost of more battery).
Absolutely! You can customize every screen with your preferred metrics and choose from 6 grid layouts (1×1, 1×2, 1×3, 2×1, 2×2, 2×3). Metrics are organized in categories with search, and each activity type can have its own layout configuration. You can manage layouts directly from your iPhone or on the Watch.
Trekka auto-saves your activity every 30 seconds. If the app crashes or is terminated, you can recover your full activity when you reopen the app. This periodic save system ensures you never lose your data, even during 8+ hour activities.
The storm alarm monitors barometric pressure from Apple Watch's built-in sensor. When it detects a rapid drop (greater than 4 hPa in 3 hours), it sends a haptic warning notification. It includes stationary detection to avoid false positives from elevation changes. This is a potentially life-saving feature for hikers, climbers, and mountaineers.
Yes! Trekka includes full Apple Watch Ultra support: map the Action Button to "Drop Waypoint" or "Toggle Map Zoom," auto Water Lock for water sports, and quick-access to the Ultra's 86dB emergency siren. Layouts are optimized for the larger 49mm display.
Trekka includes multiple battery optimization features. Low Power Mode reduces GPS update frequency for multi-day adventures. On watchOS 9.0+, it's compatible with Apple's system Workout Low Power Mode — maintaining full GPS and heart rate accuracy while reducing other system consumption. You can also toggle Precise GPS on or off to balance accuracy vs. battery life. Typical usage is 15–20% per hour standard, 8–12% with low power mode.
Yes! You can export activities from the app's Settings. Activities are also automatically saved to Apple Health (with your permission). You can export GPX files with full route data for sharing or analysis in other apps.
Trekka requires Apple Watch Series 4 or later running watchOS 10.0+, and an iPhone with iOS 17.0+ for the companion app. The Watch app works standalone, but the iPhone provides additional features like activity history, route management, and settings sync.
Please check the App Store listing for current pricing. Trekka is designed to provide serious value for outdoor enthusiasts with professional-grade features you won't find in generic fitness apps.
Trekka provides GPS tracking, route guidance with GPX import, backtrack mode, off-trail detection, ETA calculations, and coordinate display (decimal, MGRS, UTM). However, it should not be relied upon as your sole means of navigation. Always carry appropriate maps, a compass, and other navigation tools. GPS accuracy can vary, and device batteries can fail. Use Trekka as a powerful supplement, but always prioritize safety.
