ZTFit is a free companion app for smart bracelets and smartwatches, developed by Shenzhen ZhanTuan Technology Co., Ltd (深圳市战团科技有限公司). With over 1 million downloads on Google Play and availability on iOS, ZTFit connects budget Bluetooth wearables with your smartphone — delivering health monitoring, exercise tracking, watch face customization, and smart notifications in one lightweight interface.
Designed for users of affordable ZTFit-compatible smartwatches including models like the T900 Ultra, ZT Pro10, ZT Max20, Watch X, and HIWATCH ULTRA GS, the app provides practical fitness and health features including step counting, sleep analysis, heart rate monitoring, and multiple sport modes — all completely free with no subscription.
How ZTFit Works
ZTFit connects to your smartwatch or smart bracelet via Bluetooth Low Energy (BLE). Once paired, the app syncs health data — step counts, heart rate readings, sleep records, and workout logs — from your wrist to your phone. Data is displayed in clean daily summaries so you can monitor your activity and health trends.
The app also serves as a notification bridge: incoming calls, SMS messages, and app alerts (WhatsApp, WeChat, Facebook, etc.) are forwarded from your phone to your watch, so you stay informed without constantly reaching for your phone. You can even reject incoming calls directly from your watch.
