OnWear

OnWear is a free companion app developed by Shenzhen Lingwei Innovation Technology Co., Ltd. (iOS) and Watch Tech Dev (Android) for LinWear LW-series sports smartwatches. Once paired with your watch via Bluetooth, OnWear syncs daily steps, distance, calories burned, sleep stages (deep/light/awake), and continuous heart rate data from your watch to your phone. It also pushes phone call and SMS notifications to your watch, supports reminders (sedentary alerts, alarms), and includes an anti-loss feature. OnWear is free on both Google Play (com.lw.linwear) and the App Store (id1522652325). The advanced version, OnWear Pro (com.linwear.top), adds blood pressure, blood oxygen (SpO₂), and respiratory rate for supported devices like the LW61.

To connect OnWear to your LinWear smartwatch: (1) Download OnWear from the App Store (id1522652325) or Google Play (com.lw.linwear). (2) Open the app and create an account or log in. (3) Enable Bluetooth on your phone. (4) Power on your LinWear watch and make sure it's in pairing mode (usually shown on the watch screen). (5) In the app, tap the 'Add Device' or pairing button. (6) Select your watch from the scan list. (7) Confirm pairing on both devices. If prompted, grant phone, SMS, and notification permissions to enable notification forwarding. Keep both devices within 1–2 meters during initial pairing.

OnWear is designed primarily for LinWear LW-series sports smartwatches. The base OnWear app (com.lw.linwear) lists the LW15 as its primary associated device. OnWear Pro (com.linwear.top) lists the LW61. Both apps describe themselves as compatible with 'all kinds of sports watches,' suggesting they may work with other generic Bluetooth fitness watches using the same communication protocol. If your watch packaging shows a QR code pointing to OnWear, or the setup guide says to download OnWear, that's the correct app. For full health features (blood pressure, SpO₂), ensure you're using OnWear Pro with a compatible watch model.

OnWear (com.lw.linwear) is the base companion app for LinWear sports watches (primarily LW15), offering step tracking, sleep monitoring, heart rate, call/SMS notifications, and basic reminders. OnWear Pro (com.linwear.top, formerly LinWear) is the advanced version associated with the LW61 and other higher-end models. OnWear Pro adds blood pressure monitoring, blood oxygen (SpO₂) readings, respiratory rate tracking, and richer lifestyle reminders (sedentary alerts, intelligent alarm clock, anti-loss). OnWear Pro also has more downloads (1M+ vs 500K+) and a higher Google Play rating (3.6 vs 3.3). Both are free. Choose OnWear Pro if your watch supports the extended health sensors.

Common OnWear connection issues and fixes: (1) Bluetooth off — ensure Bluetooth is enabled on your phone; force-close the app and reopen it. (2) Distance — keep phone and watch within 1–2 meters. (3) Clear cache — go to phone Settings > Apps > OnWear > Storage, clear cache and data, then relaunch. (4) Re-pair — remove the watch from OnWear and your phone's Bluetooth settings, then pair again. (5) Update the app — download the latest version from the Play Store or App Store. (6) Restart both devices — power off both phone and watch, restart, and try pairing again. (7) Permissions — ensure Location, Bluetooth, and Notification permissions are granted to OnWear. If issues persist, contact Watch Tech Dev support via the app's support section.

Yes. OnWear integrates with Apple Health (HealthKit) on iOS. When enabled, the app syncs your exercise data, sleep records, and heart rate from your LinWear watch into the Apple Health app. OnWear Pro also syncs blood pressure, blood oxygen (SpO₂), and respiratory rate to Apple Health when your watch supports those sensors. To enable: open OnWear on iOS and follow the prompt to authorize Apple Health access, or go to Settings > Privacy > Health > OnWear to manage permissions. There is no Google Fit integration mentioned for the base OnWear app.

Yes. Both OnWear (com.lw.linwear) and OnWear Pro (com.linwear.top) are completely free to download and use on Android and iOS. There are no subscription fees, premium tiers, or in-app purchases. All features — health tracking, notification forwarding, reminders, device management, and Apple Health sync — are included at no cost. The apps are bundled conceptually with LinWear hardware purchases and serve as free utilities for compatible smartwatch owners.

To set up notifications in OnWear: (1) Make sure your watch is connected via Bluetooth. (2) Open the OnWear or OnWear Pro app. (3) Navigate to Device or Notification settings in the app. (4) Enable call notifications (requires phone permission) to receive caller ID on your watch. (5) Enable SMS notifications (requires SMS permission) to see message content on the watch. (6) For third-party app notifications (WhatsApp, WeChat, Line), find the app notification list and enable the apps you want. (7) On Android, you may need to grant 'Notification Access' in phone Settings > Accessibility > Notification Access. For iOS, approve notification permission when the app first asks.

OnWear tracks: steps, distance, and calories burned (daily and weekly summaries); sleep monitoring with deep sleep, light sleep, and awake stage breakdown; and continuous heart rate with historical chart. OnWear Pro adds: blood pressure measurements (requires compatible watch hardware), blood oxygen saturation (SpO₂), and respiratory rate. The app also offers sedentary reminders to prompt movement, and syncs all iOS health data with Apple Health. Note that all measurements are consumer-grade wellness readings from optical and sensor hardware — not medical-grade data. Accuracy depends on watch hardware quality and proper wearing position.

To update your LinWear smartwatch firmware via OnWear: (1) Connect your watch to the OnWear app via Bluetooth. (2) Navigate to Device Settings or the device management section in the app. (3) Look for a 'Firmware Update' or 'System Update' option. (4) If an update is available, tap to download and install. (5) Keep your watch charged and close to your phone during the update. (6) Do not turn off either device during the update process. If a firmware update fails or shows 'upgrade terminated,' restart both devices and try again. If issues persist, contact Watch Tech Dev support — their team typically responds with troubleshooting guidance including video instructions.
