Live Race Stats on Amazfit: your race position on the watch screen

Live Race Stats is a free app for Amazfit watches. At races timed by our system it shows your place, the gaps to your rivals and the leader, how those gaps are changing, and your laps — right on the watch screen.

What you need

• An Amazfit watch on Zepp OS 3.0 or newer (for example GTR 4 or Active 2).
• Your phone nearby with internet and the Zepp app installed — it acts as the bridge for the watch.
• A race timed by our system: you will need the competition ID and your bib number.

Installation

Find Live Race Stats in the app store inside the Zepp app and install it on your watch. The app is free.

Setup (in the Zepp app on your phone)

Open the app settings and fill in three fields:

• Site URL — the address of the results site.
• Competition ID — the race number.
• Bib number — your start number.

Below that you pick a metric for each row of the screen, so you decide what to see on the watch and in what order.

Which metrics you can show

• Place abs / Place gr — place overall and within your group, as "place/total".
• Gap ahd / Gap bhd / Gap ldr — the gap to the rider ahead, from the rider behind, and to the leader.
• Dynam ah / bh / ld — how those gaps changed over the last lap: did you close in or lose ground.
• Laps — laps completed.

Every metric comes both for the overall standing (abs) and for your group (gr).

How to read the values

• 3/4 — you are third of four.
• +0:22.0 — the rider ahead is 22 seconds up the road.
• -0:11.3 — you are 11.3 seconds ahead.
• -- — no data yet.

How it works

The watch cannot reach the internet on its own. A service part of the app inside Zepp on your phone makes the request to the site and hands the ready answer to the watch — so the phone must be nearby and online. The server computes every value and the watch only displays it, which means new metrics can be added on the site without updating the watch app.

Supported devices

Round 466 and 480 pixel screens and square 390 ones on Zepp OS 3.0 and newer. Verified on Amazfit GTR 4 and Amazfit Active 2.

If you own a different device

If you have another wearable that can run apps, you can write your own client: the data comes from our site's open API and needs no authentication.

Request: GET https://universalbicycle.team/api/v1/live-stats/{competition_id}/{bib}, where competition_id is the numeric race id from the competition page URL and bib is the start number.

The response is JSON whose stats field is a "key → string" dictionary: place, gaps, their per-lap dynamics and laps. If there is no snapshot yet for that race/bib pair you get a 404 — just retry later; polling more often than once every 30–60 seconds makes no sense.
