Trail Sense

Trail Sense is a navigation application developed by Kyle Corry, packaged as a single Android APK of version 8.2 weighing in at 12.66 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

1. Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
2. File size is a light 12.66 MB, so it installs quickly even on modest connections.
3. This build is signed by "Kyle Corry" — always verify the developer name matches what's listed on the app's official store page before installing an update.
4. After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
5. We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

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 is 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 and Sunrise Alerts.

Is Trail Sense free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does Trail Sense require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is Trail Sense safe to install?
We link to the exact APK published by Kyle Corry. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update Trail Sense?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.

1. Tap the Download APK button above and save the file to your device.
2. Open your device Settings → Security (or Apps → Special access → Install unknown apps) and allow your file manager or browser to install unknown apps for this one file only.
3. Open the downloaded com.kylecorry.trail_sense.apk file from your Downloads folder.
4. Tap Install and wait for Android to finish.
5. Open «Trail Sense» by Kyle Corry and grant only the permissions it actually needs.
6. Revoke the "unknown sources" permission once you are done installing.
