MasWear is a free companion app for Bluetooth smartwatches and fitness bands, developed by Shenzhen United Power Technology Co., Ltd.. Available on both Google Play (500K+ downloads, 2.8-star rating from 3.78K reviews) and the App Store (2.9-star rating from 50 ratings), the MasWear app connects your wearable device via Bluetooth to track health metrics, manage notifications, and customize watch faces — all without subscription fees or in-app purchases.
The MasWear app pairs with smart watches like the MS PEAK9, MS WatchUltra, and various third-party Bluetooth watches including Hammer Active 2.0, MD3 Max, Series 7 Mini, and Ultra 8. It serves as the central hub for syncing, visualizing, and managing health data from your connected smartwatch or fitness band.
How the MasWear App Works
The MasWear app connects to your smartwatch or fitness band via Bluetooth. Once paired, it continuously syncs health data — steps, distance, calories, heart rate, and sleep patterns — from your wearable to your phone. Data is displayed in daily summaries, 30-day reports, and trend charts for easy analysis.
The app also acts as a notification bridge: incoming calls, SMS, and app alerts (WeChat, WhatsApp, Facebook, etc.) are forwarded to your connected watch. You can answer or reject calls, quickly reply to text messages, configure health monitoring schedules, set activity goals, and customize watch faces — all from a single interface.
