SZOS

SZOS does a solid job tracking my daily activity. Step counting is accurate when compared to my treadmill. Heart rate monitoring during exercise is useful. Sleep tracking gives good insight into my rest patterns. The rewards system with points is a fun touch.

Decent companion app for budget SZOS watches. Pairing was straightforward via Bluetooth. Notifications for calls work well. SpO2 reading seems reasonable. The gamification aspect with points and lucky draws keeps me opening the app daily. UI could be more polished.

I use SZOS mainly for sleep monitoring and step tracking. The sleep quality map visualization is really helpful — I can see my deep vs light sleep trends over weeks. Call notifications come through reliably. Free with no subscriptions is a big plus.

For a free app paired with a budget smartwatch, SZOS delivers the basics well. Steps, heart rate, blood oxygen all track and sync. The multi-device support is handy — I paired two watches. Would appreciate faster data sync and more watch face options.

Good app for my SZOS smartwatch. Heart rate and SpO2 monitoring work well. The rewards points system motivates me to check my health data daily. Call notifications and find phone feature are very useful. Battery-friendly — doesn't drain my phone much.

SZOS tracks the basics — steps, sleep, heart rate. Blood oxygen readings seem consistent. The lucky draw and points system is a fun addition. Connection drops occasionally but reconnects automatically. Good value for a completely free app with no ads in health sections.

Paired my SZOS watch instantly. All health tracking features work — steps, heart rate, SpO2, sleep. The sleep quality map is my favorite feature. Notifications come through for calls and messages. Multi-device support lets me switch between two watches. Recommended.

Does what it promises for health tracking. Step counter is accurate and sleep analysis gives useful breakdowns. Heart rate monitoring throughout the day helps me stay aware. The gamification rewards keep it interesting. Wish the weather feature was more reliable.

Surprisingly feature-rich for a free smartwatch app. Blood oxygen monitoring, heart rate tracking, and sleep analysis all work well with my SZOS-695 watch. The points reward system and lucky draws are unique — haven't seen that in other watch apps. Simple and does the job.

Blood Oxygen (SpO₂) Monitoring

SZOS supports blood oxygen saturation measurement for watches equipped with SpO₂ sensors. This metric offers a general wellness indicator — particularly useful during exercise or sleep. As with all consumer wearables, these readings are for reference only and not intended for medical diagnosis.

Sleep Monitoring

The app provides sleep quality tracking that records total sleep duration and breaks it down into stages. A visual "sleep quality map" summarizes your nightly patterns, helping you identify factors that affect your rest. Weekly reports reveal sleep trends over time.

Body Status Assessment

SZOS integrates heart rate, blood oxygen, and activity data to provide an overall body status evaluation, giving you a holistic snapshot of your daily health and fitness level.

Gamified Rewards System

One of SZOS's standout features is its gamification and rewards system:

• Participate in in-app activities and events to earn points
• Accumulated points can be redeemed for gifts or rewards
• Lucky draw mechanics add engagement and fun
• Designed to motivate consistent health tracking habits

Smart Notifications & Connectivity

Call & App Alerts

SZOS pushes incoming call notifications to your watch, displaying caller ID on your wrist. App notifications from messaging and social media platforms can also be forwarded.

Find My Phone

Activate the "find phone" function from your watch to make your phone ring, helping you locate it quickly. Note: this feature requires the SZOS app to be running in the background.

Weather Display

Current weather conditions can be displayed on your watch face. Some users have noted that weather accuracy may vary by region.

Remote Camera & Music Control

SZOS supports remote camera shutter control and music playback from your watch, though user feedback indicates these features may have limited functionality depending on the watch model.

Multi-Device Support

SZOS supports connecting multiple wearable devices simultaneously. Data from each paired watch syncs to the same app, allowing you to manage and compare health data across devices.

Compatible Devices

SZOS is designed for SZOS-branded smartwatches, including the SZOS-695 series and other models distributed through online marketplaces. If your watch's packaging includes a QR code pointing to SZOS or instructs you to download the "SZOS" app, this is the correct companion app.

SZOS is published by XiZhi Communication (晟谷). The app collects location data, health and fitness data, and device identifiers. According to the App Store privacy label, precise location may be used for third-party advertising. Health and fitness data is listed as "not linked to your identity."
