Mountain Log Japan

Off route? It now suggests a section to the nearest trail. Descent estimates skip rest time, and course times update offline. Pro is one-time - no subscription.

Record every hike with GPS, plan course times, and bring past climbs back to life just by scanning your photo library. Track your progress on Japan's 100 Famous Mountains. One-time purchase - no subscription.

■ NEW IN THIS VERSION

[Better help when you go off route]

• If you stray from your route, the app searches for nearby trails and asks whether to fill in the section to the closest one
• Off-route checks start only after you reach the start of your route - no false alarms on the way to the trailhead
• Off-route distance is measured to the route line itself for more accurate detection
• Your heading is shown on the current-location marker, even on a north-up map

[More accurate course times and descent estimates]

• Time spent standing still is excluded from your estimated finish time, so breaks don't skew it
• Pace multiplier now goes up to 2.0x to match slower, steadier hikers
• Recalculate course times even with no signal
