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.

Great app and I have recorded 46 routes since I used it already. I hope the developer can keep on the development of this app. If it is keeping improving and have more functions I don’t mind to pay for downloaded

Many bugs but overall a great app

The trails and information are all very up-to-date and it's great for looking for the perfect trail, but there are many bugs. Search bar doesn't even work and I have to restart the app, some users I search up don't even show up (even though they are accounts made by the people I know) and signing in with your Apple ID makes it so you cannot sign in from any other device other than your own

Developer Response ,

For the search bar, please make sure you are searching in the "Dashboard" tab for your own records, and "Browse" tab from other public routes. For the user search for being friends, please search in the "Friends" tab.

For the Apple ID login, please make sure you have select using your apple id (email) for apple login and not selecting hiding your email while registration. Then, you can login by your email if you use as your apple id. If you have other consideration to change your login in method, please email for details.

Please also enhance map’s details. The text in map is too small. And there is no name for start and end point. If the app allow user to edit Start and End point’s names. Or app is able to pick a close area as a start or end points’ names automatically, then it would be very helpful.
