Grad-X

GradX is your all-in-one outdoor companion for cycling, hiking, trail running, and skiing. Know exactly what's ahead — every climb, every descent, every degree of slope — in real time. - REAL-TIME SLOPE & GRADIENT DETECTION See the gradient of the road or trail ahead before you reach it. GradX shows a live elevation profile and grade percentage (▲ uphill / ▼ downhill) so you can pace your effort and never get caught off guard by a steep climb. - OFFLINE NAVIGATION Turn-by-turn navigation that works without signal. Vector maps are stored on your device, so you can navigate deep in the mountains or out of coverage with zero data usage. - HEART-RATE MONITORING Connect any standard Bluetooth heart-rate sensor (chest strap or armband) and track your BPM live on the heads-up display. Train smarter and stay in your target zone. - LIVE WEATHER ALONG YOUR ROUTE GradX checks the weather at points all along your route — not just your current spot. Spot incoming rain, snow, or storms before they hit, with clear icons right on the map and in the navigation banner. - ELEVATION PROFILE & CLIMB STATS A live elevation chart shows the terrain ahead during navigation and free exploration, with real-time grade so you always know how hard the next stretch will be. - ACTIVITY TRACKING Record your rides, hikes, and runs with GPS tracking. Review your route, distance, and elevation gain.
