About this app

TrailWatch: Your Best Hiking Guide

Hike with a purpose: join us in protecting Hong Kong’s country parks!

TrailWatch is the first smartphone app in Hong Kong that combines conservation with the appreciation for Hong Kong’s country parks.

When you hike with TrailWatch, you can track your hikes in real-time using GPS, and help surveil the countryside by reporting unusual incidents. You can also plan and share your trails, as well as check out routes created by other users.

Enjoy. Share. Protect.

Key Features

Hiking record: Supplement records of your hikes with your own photos and statistics calibrated by the app, including elevation, length, distance, speed, calories burnt etc.

Browse routes: Find feature trails or routes near you and bookmark them—or customise them to suit your needs! Search for featured and routes near you and start tracking, or modify and bookmark them to suit your preferences

Plan routes: Plot routes simply by tapping the start and end points—and the app will map the rest of the trail for you. If you wish, you may personalise the route and add points of interest.

Invite friends: Create a group tracking event and send your TrailWatch friends an invitation! The invitation will contain everything your friends need to know, including route details, where to meet, and so on.

Locate friends: Using internet data, members of a group tracking event can identify the real-time locations of all participants. This means even those who have wandered off course can be located.

Share photos: All photos taken by group members can be automatically uploaded to the group tracking event and shared with all members without making additional settings.

See who finished fastest: The time spent by each individual group member to complete a group tracking event will be published on a list after the event has ended.

Safeguard our trails: Users are encouraged to monitor and protect country parks by reporting unusual incidents during their hikes. “Concrete Path,” a new category of incidents, allows users to report concrete paved walkways along trails.

TrailWatch offers four kinds of maps: the TrailWatch HK Map, TrailWatch Terrain Map, Open Cycle Map, and MapBox Streets Map.

It tracks route clearly on the map, distance, calories, and allows photos along the way. Very good However, there is a bug in attaching photos where without selecting categories will not attach. It should attach after the tick is pressed.

The same trail record has been duplicated 240 times, and there is no way to delete them in one go. I am truly disappointed with this unfriendly user interface! I have decided to delete this app

Hi Wong, our server was having an issue at that time; therefore, an unexpected issue occurred. We sincerely apologise for causing any inconvenience to you.

Just installed. Found that the share function only share to Whatsapp, which is not very useful. Both Android and iOS have API for an App to share links to all other Apps. Please consider to update and use it.

Of course you can share through other app! The default sharing is set on your own phone, which is not related to TrailWatch.
