Belt Control — treadmill control in the browser

Using a WalkingPad without the KS+Fit app

You don't need an account, a phone, or the manufacturer's software to run a KingSmith treadmill. There's no password standing between your pad and any app that knows how to talk to it — and a web browser can.

What you actually lose without the app

Most WalkingPads come with a small remote, and for walking it's genuinely enough: start, stop, faster, slower. What the remote can't do is remember anything. No history, no daily total, no goal — and the numbers on the treadmill's own display reset the moment you finish.

That memory is what the phone app is really for. The price of it is an account, a login, notifications, and your walking data sitting on somebody else's server. For a lot of people that's a bad trade, which is why this page exists.

How the browser one works

Modern browsers can connect to Bluetooth devices directly, once you pick the device from a list the browser shows you. That's all this is. There's no pairing code to type, no extra software in between, and nothing goes to a server — your browser talks to your treadmill over Bluetooth, the same way your headphones do.

In practice: open the page in Chrome or Edge, press Connect, and pick your pad from the list. The app then works out for itself how to talk to your particular treadmill. Which pads that covers.

What you get

Where your data lives

In the browser you used, on your own device, and nowhere else. Nothing is uploaded and there's no account to make.

That has a real cost worth saying plainly: clear your browsing data and your history goes with it, and a walk recorded on your laptop won't show up on your tablet. The backup file exists for exactly that reason — it's how you move your history, and it's on you to save one.

Nothing to install. Open it in Chrome or Edge with the treadmill switched on and nearby.

Is it safe to run a treadmill from a web page?

It's exactly as safe as running it from the phone app — which is to say the belt can start with nobody standing on it, and that's true of every option on this page, remote included.

What the app does about it: starting and resuming both ask you to confirm and show the speed first; the speed is capped to what your treadmill says it can do, and capped again in case a pad reports something nonsensical; Stop is always available, works with the Esc key, and stays pinned on screen from the moment you press start until the belt reports it has stopped. And the app never reconnects on its own, because silently reattaching to a treadmill that might be moving is not a safe thing to do.

Those reduce the risk rather than removing it. Closing the page does not stop the belt. Use the treadmill's own controls or safety key as the real stop.

Does it need an internet connection?

Only to load the page the first time. After that it keeps a copy and works offline — the connection to your treadmill never used the internet in the first place.
