Introduction
Fundo Wear is a free smartwatch companion application developed by Shenzhen Fenyun Technology Co., Ltd. (深圳市分云科技有限公司) and available on both Google Play and the Apple App Store. With over 1 million downloads on Android, it is one of the most widely used companion apps for budget Bluetooth smartwatches — particularly generic, unbranded wearables that ship without a dedicated brand app.
If your watch's packaging or setup screen points you to download Fundo Wear, this guide explains everything: how to connect your smartwatch, what features it offers, how it compares to the newer FunDo Pro app, and answers to the most common questions.
What Devices Are Compatible with Fundo Wear?
The Fundo Wear app supports a range of low-cost Bluetooth smartwatches and fitness bands. Compatible models officially listed by the developer include:
AX9 series smartwatches
SX9 series smartwatches
DM09 smartwatch
GT88 smartwatch
TFL-1 / EPIC04 models
R02S-V008 and R02S-D10
IW-P9 and similar generic models
In practice, many low-cost Bluetooth smartwatches that advertise "Fundo Wear support" or ship with QR codes linking to Fundo are compatible. These watches are commonly sold on Amazon, AliExpress, and other marketplaces under various brand names.
How to confirm compatibility: Install Fundo Wear, enable Bluetooth, and tap the connection button. If your watch appears in the scan results, it is supported.
What is Fundo Wear and which smartwatches does it support?
Fundo Wear is a free smartwatch companion app developed by Shenzhen Fenyun Technology Co., Ltd. (also known as 深圳市分云科技有限公司) and available on Google Play and the Apple App Store. It is designed for low-cost Bluetooth smartwatches including the AX9 series, SX9 series, DM09, GT88, TFL-1/EPIC04, R02S-V008, R02S-D10, and IW-P9 models. Many generic, unbranded smartwatches sold on Amazon, AliExpress, and other marketplaces ship with a QR code that links to Fundo Wear. If your watch shows a QR code pointing to 'Fundo' or 'Fundo Wear' during setup, this is the correct app to use.
How do I connect Fundo Wear to my smartwatch?
To connect Fundo Wear: (1) Install the app from Google Play or the App Store. (2) Enable Bluetooth on your phone. (3) Open Fundo Wear and grant the required permissions (Bluetooth, Location, Notifications). (4) Tap the Bluetooth connection button on the home screen. (5) Select your watch from the list of scanned nearby devices. (6) Wait for the initial data sync to complete. If you experience frequent disconnections on Android, go to Settings → Apps → Fundo Wear → Battery and set it to 'Unrestricted' so the OS doesn't kill the app in the background.
What is the difference between Fundo Wear and FunDo Pro?
Both Fundo Wear and FunDo Pro are developed by Shenzhen Fenyun Technology, but they support different smartwatch ecosystems. Fundo Wear is designed for AX9, SX9, DM09, and GT88 series watches and focuses on Bluetooth voice calls, SMS sync, and basic health tracking. FunDo Pro supports SW, GT, GW, and SH series watches and offers more advanced features like 7 sports modes and Apple Health integration. The apps are not interchangeable — you must use the one your specific watch requires. Check the QR code on your watch or packaging to determine which app to download.
Where can I download the Fundo Wear APK for older versions?
If you need an older or alternative version of Fundo Wear for Android, you can download APK files from trusted mirror sites. The most reliable sources are Uptodown (fundo-wear.en.uptodown.com/android) and APKPure (apkpure.com/fundo-wear/com.kct.fundowear.btnotification). The current version is 3.7.4. Always download from reputable sites and scan the file with your antivirus before installing. Avoid random sites offering 'modded' or 'premium unlocked' versions, as these may contain malware.
Is Fundo Wear free? Are there in-app purchases?
Yes, Fundo Wear is completely free to download and use. There are no subscription fees, no premium tiers, and no in-app purchases listed in either the Google Play or App Store listings. All features — including step tracking, sleep monitoring, heart rate, Bluetooth calls, notifications, and camera remote — are available at no cost.
Can I add custom watch faces with Fundo Wear?
Fundo Wear itself does not include a built-in watch face store or custom watch face gallery. The available watch faces depend on the smartwatch hardware and its firmware. Some compatible smartwatches come with a few pre-installed watch face options that can be cycled through on the device itself. For additional watch face customization, you may need to check if your specific watch model supports third-party watch face apps or firmware updates from the manufacturer.
Why does Fundo Wear keep disconnecting from my watch?
Frequent disconnections are usually caused by the phone's battery optimization killing the Fundo Wear background process. Fixes: (1) Android: Settings → Apps → Fundo Wear → Battery → set to 'Unrestricted'. Also lock Fundo Wear in your recent apps list so it stays running. (2) Make sure Bluetooth is always enabled. (3) On Android, keep Location services enabled (required for BLE scanning). (4) Try toggling Bluetooth off and on to force reconnection. (5) Check that 2.4 GHz Wi-Fi isn't causing interference (Bluetooth and 2.4 GHz Wi-Fi share the same frequency band). (6) Make sure you're within Bluetooth range (typically 10 meters / 33 feet).
What is a good Fundo Wear alternative app?
The best Fundo Wear alternative depends on your specific smartwatch — most companion apps only work with their own device ecosystem. Common alternatives for budget wearables include: FunDo Pro (same developer, for SW/GT/GW/SH series watches), Da Fit (by Mo Young Limited, for CRREPA-protocol devices), VeryFitPro (for Bozlun/iWOWN-protocol watches), HryFine, and GloryFit. For open-source options, Gadgetbridge is an Android app that supports many generic wearables without requiring a cloud account. Only use an alternative if your specific watch model is confirmed compatible.
Can I use Fundo Wear on a PC or Mac?
Fundo Wear does not have an official Windows or Mac desktop application. It is designed for Android (4.3+) and iOS (7.0+) smartphones. On Apple Silicon Macs running macOS 11 or later, you may be able to install the iOS version. You can technically run the Android version on a Windows PC using an Android emulator such as BlueStacks, but Bluetooth device pairing may not work correctly in a virtual environment. For full functionality, Fundo Wear should be used on a real Android or iOS phone.
Does Fundo Wear support cloud data backup?
Yes, Fundo Wear supports cloud data synchronization. Your motion and health data (steps, sleep, heart rate) can be synced to a cloud service for permanent storage. This means your fitness history is preserved even if you switch phones or reinstall the app. However, note that the developer's privacy practices have not been fully disclosed — the App Store notes that the developer has not provided detailed privacy information.

Scratchy audio (very) while receiving phone calls through the watch. The Bluetooth connection works but the call quality could be much better. Steps and sleep tracking are decent though. Wish the app had a more modern interface.

Pricing InfoFundo Wear is completely free with no in-app purchases, subscriptions, or premium tiers. All features including step tracking, sleep monitoring, heart rate, Bluetooth calls, notifications, cloud sync, and camera remote are available at no cost.
Works fine for what it is — a basic companion for my cheap smartwatch. The step counter is reasonably accurate and I like the daily charts. The heart rate readings seem about right compared to my doctor's readings. The app hasn't been updated in a while though.
App Store
Simple and does the job. I use it mainly for step counting and notifications. The Bluetooth calls feature is a nice bonus even if the audio quality isn't perfect. Cloud sync means I don't lose my data. Free with no ads — can't complain.
App Store
The sleep monitoring works okay but doesn't break down deep vs light sleep like some other apps. Steps are accurate. Camera remote shutter is fun for group photos. Would be nice if the developers updated it more frequently — the iOS version feels abandoned.
App Store
Got this for my GT88 watch. After some initial pairing trouble, it connected and has been working steadily. Steps, heart rate, and notifications all sync fine. The interface is dated but functional. For a free app with no subscriptions, it covers the basics well enough.
Google Play
The app works fine for basic fitness tracking. My AX9 watch connects reliably and steps sync every time I open the app. Sleep data is basic but useful. Main complaint: the app looks like it was designed in 2015. A UI refresh would go a long way. But it's free and functional.
Google Play
Been using this with my DM09 watch for almost a year. The Bluetooth calling feature actually works well — better than I expected from a budget watch. Step counter and heart rate are reliable. Cloud sync keeps my data safe. Would love to see watch face customization added.
Google Play
Decent companion app for cheap smartwatches. Paired with my SX9 without issues. Notifications come through reliably from WhatsApp and WeChat. The camera remote is useful. Steps seem accurate compared to my phone's pedometer. Would appreciate Google Fit integration.
Google Play
Surprisingly functional for a free app. Heart rate tracking works well on my R02S watch. The monthly charts help me see trends. Cloud backup is a great feature — I changed phones and all my data carried over. Only downside is no dedicated sports modes like FunDo Pro has.
Google Play
Works with most generic Bluetooth watches I've tried. The app is simple and straightforward. Steps, sleep, and heart rate all function as expected. The find-my-watch feature has saved me a couple of times. Wish it supported more modern watch protocols, but for older budget watches it's the go-to app.

Once paired, the Fundo Wear app enables real-time Bluetooth voice calls through your smartwatch. You can make and receive calls, sync your phone's contact list to the watch, and read SMS messages directly on your wrist. This is one of Fundo Wear's standout features compared to many budget smartwatch apps.
Smart Notifications
The app pushes incoming call alerts, SMS notifications, and third-party app notifications (such as WhatsApp, Facebook, and other social apps) from your phone to the watch display in real time.
Step Counting & Activity Tracking
Fundo Wear records your daily step count, estimates calories burned, and tracks walking distance. Data is synced from the watch via Bluetooth and displayed in clear daily and monthly charts. You can set exercise goals (campaigns) to encourage regular workouts.
Sleep Monitoring
The app monitors your nightly sleep status and duration, providing basic sleep tracking data that helps you understand your rest patterns over time.
Heart Rate Monitoring
For watches with an optical heart rate sensor, Fundo Wear collects and displays heart rate readings throughout the day, helping you keep track of your cardiovascular health trends.
Cloud Data Sync
Motion and health data can be synchronized to a cloud service for permanent storage. This means your fitness history is preserved even if you switch phones or reinstall the app.
Remote Camera Control
Use the smartwatch as a Bluetooth remote shutter to trigger the smartphone camera from a distance — ideal for group photos and selfies.
Anti-Lost & Find Device
The app includes a Bluetooth anti-lost alert and a "find device" function that can make your misplaced watch ring, helping you locate it quickly.
Multi-Language Support
Fundo Wear supports 13 languages including Simplified Chinese, Traditional Chinese, English, German, French, Spanish, Italian, Japanese, Korean, Russian, Portuguese, Romanian, and Greek.

Connection tip for Android: If Fundo Wear frequently disconnects in the background, go to Settings → Apps → Fundo Wear → Battery and set it to Unrestricted. Most disconnection problems are caused by the OS killing the app to save power.

Bottom line: Only use Fundo Wear if your watch specifically requires it. These apps are not interchangeable — each works only with its own supported device ecosystem. If your watch QR code points to "Fundo Wear," use Fundo Wear; if it points to "FunDo Pro," use FunDo Pro.
Privacy and Safety
Fundo Wear is published on both official app stores and is the legitimate companion app for many budget smartwatches. Users should note:
Permissions: The app requests Bluetooth, location, contacts, and notification access. These permissions are needed for its core features.
Download only from official stores: APK files from unofficial third-party websites may be outdated or modified. Use Google Play or the App Store whenever possible.
Medical disclaimer: Fundo Wear is not a medical device. All health metrics (steps, heart rate, sleep) are for general wellness reference only and should not be used for clinical diagnosis or treatment decisions.
