Description
Explore beyond the reaches of the Internet with Trail Sense.
- Designed for hiking, backpacking, camping, and geocaching - Place beacons and navigate to them - Use as a compass (only available on devices with a compass sensor) - Follow paths - Retrace your steps with backtrack - Use a photo as a map - Plan what to pack - Be alerted before the sun sets - Predict the weather (only available on devices with a barometer sensor) - Use your phone as a flashlight - And much more!
Trail Sense is a tool, and just like any other tool that you bring into the wilderness, it's essential to have backup equipment and skills. This app is intended for information purposes only and the accuracy of the predictions and sensors are determined by a number of factors, including calibration, sensor quality, external sources, etc. Use at your own risk, always have backup tools (ex. compass), and stay safe.
This app also does not, and will never, use the Internet - all information in Trail Sense comes directly from your phone's sensors, and no data will leave Trail Sense.
COMMON ISSUES - No compass: If your phone does not have a compass sensor, there is nothing I can do to make it work because that is hardware. You will still be able to use other features of Trail Sense. - No weather: The Weather tool is only available if your phone has a barometer sensor.

I'm the only developer of Trail Sense, so I will do my best to help out with issues - but I have a limited device selection to test on.
PERMISSIONS - Notifications: Allows Trail Sense to display notifications (backtrack, weather, sunset alerts, astronomy events, water boil timer, etc) - Location: Allows Trail Sense to retrieve your location for navigation, weather (sea level calibration), and astronomy. - Background location: Allows Trail Sense to retrieve your location for sunset alerts while in the background. On some devices, this will also improve the reliability of backtrack and weather monitor. - Physical activity: Allows Trail Sense to use your phone's pedometer for distance calculation. - Camera: Allows Trail Sense to use your camera on the sighting compass, clinometer, and for taking photos used by the Cloud Scanner, QR Code Scanner, and Photo Maps. - Alarms & reminders: Allows Trail Sense to post a notification at an exact time. This is used by the Clock tool (when updating system time) and Sunset Alerts.

I love Trail Sense, so many useful features! Could an SOS signal be added to the flashlight or the whistle?

Best App Made Ever... It has all options to use all the possible tools, a phone could have maximum possible. Even I got to know later that this app could even tell About the mAh right now present and have Flash options and Red light too and Many more. I love this app, Best app which could reveal all types of possible sensors, a phone could have. Like Altimeter, etc. Even I used it to find the Height of my House by throwing the stone and using cliff height tool. This App should get 5 STAR OVERALL.

Trail Sense is a fantastic multidisciplinary app with features like the compass and speedometer, which also work great as basic navigation tools for sailing (COG and SOG). *Adding a simple Man Overboard (MOB)* feature to mark and return to specific location when sailing, along with an adding few sailing terminologies for route planning overwaters, would make it even more useful for casual boaters. Overall, it’s a perfect tool for navigation and outdoor enthusiasts.

I installed this app in my phone, the app prompts the user to accept data terms, after that it tells user that their device does not have a compass sensor. Why did your app not test first whether your app will be compatible with the user's device, before collecting user data? At least the user would have had the option to not continue with setup and avoid wastage of user's time?
