iTrailMap 3D lets you see yourself on a 3D mountain, record your tracks and upload them to the web. It also records stats like vert and distance. The app was designed for skiers and snowboarders. But it works great for mountain biking and hiking also.

- See your GPS location on the slopes.
- Record your tracks, and show them to friends later.
- Record your vertical feet and total distance skied.
- Extremely fast access to paper maps. Don't let your hands freeze while waiting for maps to download.
-Flip smoothly between 3D GPS maps and paper maps. With a single touch. (See website for iPhone compatible YouTube video demo)
-App starts up where you left off, so you are right back to viewing the current resort after startup.
-Landscape mode for both 3D maps and paper maps.
- 750+ resorts currently available. From all over the world. All have 3D models with lift lines displayed. See website for complete list of resorts. If you don't see your favorite resort, let us know and we'll add it for you ASAP!

*Note: These are not "official" trail maps. Always adhere to posted signs, trail closures, and official resort maps. Big Air Software is not affiliated with the ski resorts listed.

If you're tracks are broken up or "dotted", the iPhone's GPS is not receiving a good signal. Try putting the phone in a different pocket. An arm pocket or breast pocket is ideal.

Continued use of GPS running in the background can dramatically decrease battery life.
