Start, stop and set the speed of a KingSmith or WalkingPad treadmill from a browser tab. No phone app, no account, nothing to install.
Open it in Chrome or Edge and press Connect. Your browser talks to the treadmill over Bluetooth, the same way it would to a pair of headphones — set the speed, watch your distance, steps and calories as you walk, and keep a record of every session. Nothing is sent anywhere: your walks are saved on your own device and never uploaded.
Most of them. Belt Control doesn't go by model name — it asks your treadmill what it can do when you connect, and adapts to the answer:
Safety. Belt Control commands a motorised treadmill. Only start it when you can see the belt, and stop it with the treadmill's own controls or safety key rather than relying on this app — a Bluetooth link can drop while the belt keeps running. It is not a safety device and is provided without warranty; you use it at your own risk.
Belt Control is an independent project. It is not affiliated with, endorsed by, or sponsored by Beijing KingSmith Technology Co., Ltd. WalkingPad® and KingSmith® are trademarks of that company, used here only to say which treadmills this app can talk to.
