Quick Start
⚠️ 16.Jun. 2025
1. Restart the Tracker After Charging: Please remember to restart the tracker after charging it. If you don’t restart it, you may experience tracking lag and stop during use.
2. Magnetometers Mode Currently Unavailable: Due to an upgrade in the chip of the latest trackers, the calibration algorithm for the magnetometer is still under development. As a result, the magnetometer mode is temporarily unavailable. We apologize for any inconvenience this may cause.
3. Custom Tracker Color Issue: If you customize the tracker color and save it to the device, there may be a software error that causes the color to revert to the default blue-green after one minute of inactivity.
We are working on resolving these 3 issues in a future firmware update. It is expected to be completed by the end of June.

Label your tracker
For quick identification and wearing of each tracker, Excap provides stickers with positions. Each tracker is assigned a default pairing position upon first startup.
By clicking on the device card in Excap, you can attach the sticker to the corresponding tracker’s casing.
Installation and Wearing
Install the strap into the tracker; the wearing position is shown in the figure above.
- The tracker’s switch must be facing up.
- The tracker should be in front of your body.
- Make sure the tracker doesn’t slide on you as much as possible.
- 6/8 points mode are both supported, foots trackers are optional, if you do not need to move your ankles.
It is recommended that you try using the 6 point tracker first. Foot trackers are mounted about a quarter of the way down the inside of the foots.
