A Tool for True Adventurers

• As with any piece of gear, always carry backups and know how to use them—especially traditional tools like a map and compass.

• Data accuracy depends on several factors such as calibration, sensor quality, and environmental conditions.

• Use the app as an aid, not a replacement for experience and preparation.

*Important:

• Trail Sense never connects to the Internet.

• All information comes from your device’s sensors, and no data is collected or transmitted.

Common Questions

FAQ

Q: Does Trail Sense need an Internet connection to work?

A: No, Trail Sense never connects to the Internet. All its features operate entirely offline, drawing data only from your device’s sensors. This means you can use it anywhere in the world without worrying about connectivity or data usage.

Q: How accurate are the navigation and sensor readings in Trail Sense?

A: Accuracy depends on your phone’s hardware quality, calibration, and environmental conditions. For best results, regularly calibrate your compass and ensure your sensors are functioning properly. Remember that Trail Sense is designed to complement—not replace—traditional navigation methods such as maps and compasses.

Q: My phone doesn’t show compass data. Why is that?

A: Some phones do not include a magnetic sensor, which is required for compass-related features. If your device lacks this sensor, the compass and orientation tools will not work, but the rest of the app’s functions remain fully operational.
