Tap "Missions" at the bottom of the home screen and select "2026 Taipei Grand Trail".

Tap "View More" to pick a trail (e.g., Section 1).

⚠️ Important Reminder
For Android users, it is highly recommended to tap "Start" while you still have a strong internet connection to ensure the mission has downloaded completely.
If the screen displays "Incomplete Download," "Download Failed," or stays stuck on "Downloaded/Downloading" and won't let you press "Start," please follow these steps:
Go to the specific Offline Mission.
Tap the Delete icon (the "trash can" icon).
Once deleted, re-download the offline mission in an area with a stable internet connection.

Step 5: Start the Mission |
At the trailhead, you can switch to Airplane Mode (ensure GPS is still on).
Tap "Start Mission".

Check Data: Ensure "Distance," "Time," and "Altitude" are updating. If not, wait a moment or restart the mission until data appears.
Catching Gems: Follow the GPX path. When you are near a gem, your phone will vibrate and play a sound to notify you it has been collected.

Step 6: End & Save |
To finish, press the Red Button twice (Pause, then Stop).


Step 7: Upload Progress |
With Signal: The app uploads automatically.
No Signal: Once back in range, go to "Me" > "My Tracks" and tap "Upload" manually. Your gems will only be counted after the upload is successful.



⚠️Important Reminders
One Mission at a Time: The app only supports one active mission. If routes overlap, you must hike them separately to get gems for both.
Don't Forget to Save: Achievement only accumulates if you save and upload your records.
Refresh Offline Data: If it has been more than a month since your last record, please delete and re-download the Offline Mission under "Me" > "Offline Missions" to ensure the data is up to date. (Don't worry, your collected gems are saved to your account!)
