Introduction
Laxasfit is a free Bluetooth smartwatch companion app designed to bridge your wearable device with your smartphone. Developed by Shenzhen United Power Technology Co., Ltd., Laxasfit has surpassed 10 million downloads on Google Play, making it one of the most widely used companion apps for affordable smartwatches and fitness bracelets.
Available on both iOS (App Store ID: 6449592297, iOS 12.0+) and Android (package: com.lianhezhuli.laxasfit, Android 5.0+), Laxasfit puts complete health monitoring, workout tracking, smart notifications, and device management in one easy-to-use app.
How Laxasfit Works
Laxasfit connects to your smartwatch via Bluetooth Low Energy (BLE). Getting started is simple: download the app, grant Bluetooth and location permissions, navigate to the Device section, and scan to pair your watch. Once connected, the app continuously syncs health and fitness data from your wrist — steps, heart rate, sleep patterns, and workout records — presenting them in clean daily, weekly, and monthly dashboards.
The app also functions as a notification bridge: incoming calls, SMS messages, and alerts from apps like WhatsApp and WeChat are forwarded from your phone to your watch display, keeping you connected without constantly checking your phone.
Health & Fitness Tracking
Step Counting & Daily Activity
Laxasfit records your daily step count, distance traveled, and calories burned. Set personal step goals and compare your daily activity against weekly and monthly trends to stay motivated.
Sleep Analysis
The app provides detailed sleep tracking with a full breakdown of total sleep duration, deep sleep, light sleep, and awake periods. Review your sleep quality score and identify patterns to improve your sleep habits over time.

DeveloperShenzhen United Power Technology Co., Ltd.
Laxasfit is a free smartwatch companion app developed by Shenzhen United Power Technology Co., Ltd. with over 10 million downloads on Google Play. It connects to Laxasfit-branded smartwatches via Bluetooth and serves as your all-in-one health and fitness hub — displaying step counts, heart rate data, sleep analysis, and workout records. It also syncs calls, SMS, and app notifications from your phone to your watch, lets you download watch face designs, manage device settings, and set reminders. Available for both iOS (App Store) and Android (Google Play), it's completely free with no subscriptions.
How do I connect Laxasfit smart watch to my mobile phone?
To connect your Laxasfit smart watch to your phone: (1) Download the Laxasfit app from Google Play (com.lianhezhuli.laxasfit) or App Store (ID: 6449592297); (2) Open the app and complete the setup; (3) Enable Bluetooth on your phone; (4) Power on your Laxasfit watch and put it in pairing mode (usually by swiping to the Bluetooth/settings screen); (5) In the Laxasfit app, tap the Device section then 'Add Device'; (6) Select your watch from the scan list; (7) Confirm pairing on both devices. Once connected, grant notification access when prompted. The app will then sync data and forward notifications automatically.
Is the Laxasfit app safe?
Yes, the Laxasfit app is safe to use. It is available on Google Play and the Apple App Store, both of which require apps to pass security reviews. The app is published by Shenzhen United Power Technology Co., Ltd. and declares that all data is encrypted in transit and you can request data deletion at any time. The app collects Location, Personal info, and Health & fitness data to provide its services. As with any app, review the privacy policy at privacy.lhzl666.com for full details on data handling. The app does not require payment and contains no hidden fees.
Is the Laxasfit watch waterproof?
Water resistance varies by Laxasfit watch model. Most Laxasfit smartwatches carry an IP67 or IP68 rating, meaning they can withstand splashes, sweat, and brief water submersion (IP67: up to 1 meter for 30 minutes; IP68: deeper submersion). However, always check the specifications of your specific Laxasfit model before exposing it to water. Avoid hot water, showers, or saltwater regardless of IP rating, as these conditions can degrade seals over time. The Laxasfit app itself is a smartphone app and has no water resistance concerns.
Where can I find the Laxasfit smart watch manual?
Your Laxasfit smartwatch should include a quick-start guide in the box. For more comprehensive documentation, visit the official developer website at www.lhzl666.com. You can also search YouTube for 'Laxasfit setup' or 'how to connect Laxasfit smart watch' for video tutorials that walk through pairing, feature setup, and troubleshooting. The Laxasfit app itself also contains a help section within the device settings menu.
How do I change the watch face on my Laxasfit watch?
To change the watch face using the Laxasfit app: (1) Open the Laxasfit app and make sure your watch is connected; (2) Go to the 'Device' section; (3) Tap 'Watch Face' or 'Dial'; (4) Browse the available designs and select one you like; (5) Tap 'Apply' or 'Download & Set'; (6) Wait for the transfer via Bluetooth (usually 30–60 seconds). On supported Laxasfit models, you can also set a custom photo from your phone's gallery as the watch face — look for a 'Custom' or 'DIY' option in the watch face menu. You can also change the wallpaper directly on the watch by pressing and holding the current watch face.
What Laxasfit watches are compatible with the Laxasfit app?
The Laxasfit app is designed for Laxasfit-branded smartwatches including: Laxasfit T900 Ultra 2, Watch 9 Ultra, Watch 9 Max, Watch 8 Max/Pro/Ultra, GT4 Pro, i8 Pro Max, X8, X10 Max, H11, and other Laxasfit smartwatches and fitness bracelets. For Laxasfit MAX devices (such as the LJ515 bracelet), use the dedicated LAXASFIT MAX app. For some PRO model features (blood pressure monitoring, additional modes), use LAXASFIT PRO. If your watch packaging shows a QR code pointing to the Laxasfit app, that confirms compatibility.
How do I log into Laxasfit?
To log into Laxasfit: (1) Open the Laxasfit app; (2) On the welcome screen, tap 'Log In' or 'Sign In'; (3) Enter your registered email address and password; (4) Tap 'Sign In'. If you haven't registered yet, tap 'Register' or 'Create Account' and provide an email and password. If you've forgotten your password, use the 'Forgot Password' option to reset it via email. You can also use guest mode for basic pairing without creating an account, though a registered account allows you to sync health data across devices.
Is the Laxasfit app free?
Yes, the Laxasfit app is completely free to download and use on both Android and iOS. There are no subscription fees, no premium tiers, and no in-app purchases. All features — health tracking, workout recording, watch face management, smart notifications, device settings, and reminders — are included at no cost. The app is monetized through the sale of Laxasfit hardware devices rather than software subscriptions.
What is the difference between Laxasfit, Laxasfit PRO, and Laxasfit MAX?
Laxasfit, Laxasfit PRO, and Laxasfit MAX are three separate apps designed for different Laxasfit device variants. The standard Laxasfit app (com.lianhezhuli.laxasfit) is the main companion for most Laxasfit smartwatches — covering pairing, notifications, activity tracking, heart rate, and sleep analysis. LAXASFIT PRO (com.legend.LaxasfiPro.app) adds advanced features like blood pressure monitoring, enhanced call/SMS management, and an integrated camera remote for supported PRO models. LAXASFIT MAX (com.keya.laxasfitmax.watch.android) is specifically designed as the companion for the LJ515 smart bracelet, focusing on step counting, exercise modes, sleep tracking, and message push. Check your watch's box or QR code to identify which app is recommended for your specific Laxasfit device.

So I bought this from Temu for literally $4 and I didn't expect it to be this great because of all of the other reviews saying the contacts don't work and it doesn't notify you… well you have to go into this app and sync your info from your phone to your watch and it literally does everything an Apple Watch does pretty much! It's super simple and easy to use — you can call, text message, look at notifications, personalize your watch face with a picture from your photo album. Only took me a few minutes to figure it all out. Great value!

Pricing InfoFree to download and use on both Android and iOS. No subscription required. All health tracking, workout recording, watch face management, notifications, and device management features are included at no cost.
It's good for the price, decently affordable compared to others. I mainly use it to monitor my heart rate and it works well for that. Upsetting that I cannot reply to messages, and the sleep tracker doesn't always work perfectly. Battery life could be better, but overall it does what it says. Wish there were more customization options.
App Store
Really solid companion app for a budget smartwatch. Paired with my Laxasfit watch in under a minute and all the health features work reliably — step counting, heart rate, and sleep tracking are the highlights. Notifications come through consistently. The watch face selection is decent with good variety. Would love to see more sports modes added.
App Store
Works great for tracking my daily fitness goals. The heart rate monitor is accurate enough for my needs and the sleep analysis gives useful insights. I appreciate that there are no subscription fees — everything is completely free. Bluetooth connection is stable and the app design is clean. Good choice for anyone looking for a simple health tracker.
App Store
Decent app that does the basics well. Connected to my smartwatch without any issues and the step counting and sleep tracking are fairly accurate. The UI is simple which I appreciate. Occasional Bluetooth disconnects but it reconnects automatically. Not the most feature-rich app but it's free and does what it promises for an affordable smartwatch.
Google Play
It's good and works perfectly! But I think you should add more games since it's kinda boring, and I want to reply directly from the watch. I love that you can optionally create a custom wallpaper. At least add games like Tetris or Snake that support the watch. Also it sometimes automatically disconnects — please fix this. I'll put 5 stars when you add more features!
Google Play
If I could make a suggestion: the app needs some work on certain features — the sound is not loud enough and Bluetooth turns off occasionally. The watch time display needs to be bigger and there should be more watch face options to pick from. The weight and height personal info on the watch shows wrong values. Also wish the screen would light up when I move my wrist instead of having to push a button.
Google Play
The app is good overall but it automatically cancels workout progress and the record gets lost. I ran for 2 hours and when I checked it hadn't recorded anything — I started again and the same thing happened. I normally use Strava which works great in comparison for recording sessions. For basic health tracking and step counting the app is fine, just the workout recording needs fixing.
Google Play
This app pairs easily with my Laxasfit smartwatch and has all the essential health tracking features I need. Heart rate monitoring works well and the sleep analysis is helpful for improving my sleep habits. Notifications sync properly throughout the day. The interface is clean and easy to navigate. Could use more watch face options but overall a great free app.
Google Play
Solid fitness companion app. Accurately tracks my daily steps, heart rate, and sleep quality. The workout recording feature is useful for my morning runs. Bluetooth connection stays stable throughout the day with no major disconnects. Love that it's completely free with no hidden costs or subscriptions. Good app for basic health monitoring on a budget smartwatch.
