Spade & Co Health Smartwatch 4 Review: Big Features, Tiny Price — But What’s the Catch?
The Spade & Co Health Smartwatch 4 is aiming high — promising heart rate monitoring, blood oxygen tracking, sleep insights, and call/text alerts, all for under $100. It looks and feels like a smartwatch that should cost more than it does, and for casual users focused on fitness goals, it might just deliver enough.
This fourth-gen model refines the basics: a large color touchscreen, waterproof design, 24/7 tracking, and multi-day battery life. It supports both Android and iOS, and its companion app promises full control over health metrics and notifications.
But with a price tag this low, compromises are inevitable. There’s no app store, voice assistant, or third-party integration. Workout tracking is basic, and heart rate readings may vary during intense activity. Still, for a budget-friendly fitness-focused watch, the Spade & Co Health Smartwatch 4 hits more marks than it misses — especially for first-time buyers or anyone stepping up from a basic tracker.
If you’re looking for core health features without the premium price tag, this watch offers surprising value — just know its limits.

Smart Features & Core Tech
Spade & Co Health Smartwatch 4
Health Sensors & Metrics
The Spade & Co Health Smartwatch 4 includes a surprisingly wide range of health tracking tools for a sub-$100 device. It monitors 24/7 heart rate, SpO₂ (blood oxygen levels), sleep stages, steps and calories burned. The watch automatically tracks your daily activity and provides periodic wellness reminders like “time to move” prompts and hydration alerts.
Sleep tracking is one of its standout features, offering a breakdown of light, deep, and REM stages, with many users noting its overnight tracking as surprisingly accurate. SpO₂ readings are available on demand or automatically overnight — a premium feature rarely seen in this price range.
However, while daytime heart rate tracking is decent, it becomes less accurate during high-movement workouts, a common limitation in budget wearables that lack dual-frequency sensors or advanced filtering algorithms.
Fitness Modes & Workout Support
This watch includes over 20 sports modes, covering popular options like walking, running, cycling, elliptical, and yoga. You can initiate a workout directly from the watch and track duration, calories, and heart rate in real-time.
While the modes are useful, they’re fairly basic — there’s no auto-detection, cadence data, recovery metrics, or adaptive coaching. GPS is also not onboard, which means any location tracking must be done via your smartphone — fine for walking around the neighborhood, but less ideal for serious runners or outdoor cyclists.
In short, it's good for casual tracking but lacks the depth or precision needed by athletes or data-hungry fitness enthusiasts.
Display & Build Quality
The Spade & Co Health Smartwatch 4 uses a 1.85" TFT color touchscreen, which offers a larger viewing area than most fitness trackers in this class. It’s bright enough for indoor use and usable outdoors in shade, though it struggles a bit under direct sunlight.
The casing is lightweight plastic with a soft silicone strap that’s comfortable for all-day wear. It’s IP68 water-resistant, making it suitable for daily handwashing or light rain, though not for swimming or deep water exposure.
Build quality feels good for the price — the watch doesn’t creak or flex, and users consistently report that it holds up well with everyday wear and tear.
Smartwatch Features & Notifications
Despite its low cost, the Spade & Co Health Smartwatch 4 includes several “smart” features. You’ll get call and message notifications, app alerts (like WhatsApp, Instagram, Gmail), alarm and timer tools, and music playback control when tethered to your phone.
There’s no app store or voice assistant, so it doesn’t behave like a full smartwatch. But for core convenience — like seeing who’s calling, reading texts, or skipping songs during a workout — it does the job.
Vibration alerts are strong and customizable, and the UI is simple enough that most users can navigate the watch within minutes of unboxing.
Battery & Charging
Battery life is another strong point. The Spade & Co Smartwatch 4 promises up to 7 days per charge5–6 days of real-world use, including daily health tracking and moderate notifications.
Charging is done via a magnetic USB charger and takes roughly 1.5–2 hours to reach full capacity. There’s no wireless charging, but for a sub-$100 watch, that’s expected.
Many buyers commented positively on the low-maintenance nature of the battery — it’s one of the rare wearables you don’t have to plug in every night.
Performance & User Experience
Spade & Co Health Smartwatch 4
Health & Fitness Accuracy
For a budget smartwatch, the Spade & Co Health Smartwatch 4 delivers better-than-expected accuracy — with some caveats. Daily heart rate tracking is fairly consistent, especially when users are at rest or engaged in low-motion activities like walking or yoga. Sleep tracking also earns high marks, with users noting that the device does a solid job differentiating between light, deep, and REM sleep stages. The inclusion of overnight SpO₂ tracking adds a level of insight not typically found in sub-$100 models.
That said, performance during workouts is hit-or-miss. During high-intensity training or cardio sessions involving arm motion (like HIIT or elliptical machines), heart rate readings can fluctuate or briefly lag behind. The absence of GPS onboard also impacts the precision of run or cycling tracking unless you keep your phone with you.
Still, for casual users or beginners looking to stay active and monitor trends over time, the overall tracking performance is more than serviceable — just don’t expect medical-grade metrics or Garmin-level reliability.
Notifications & App Integration
The Health Smartwatch 4 offers a decent notification system, especially considering the price. Users receive call alerts, SMS, and push notifications from major apps like Instagram, Facebook, Gmail, and WhatsApp. Vibration feedback is strong and distinguishable, and messages are easy to read thanks to the large display.
However, you can’t reply to messages or take calls — this is strictly a viewing-only setup. There’s also no voice input or emoji rendering, which might feel limiting for smartwatch veterans. Still, users who just want to be alerted to incoming messages without pulling out their phone will find the implementation functional and straightforward.
The companion app (Spade Health App) is a mixed bag. It does the basics — shows heart rate trends, steps, sleep history — but suffers from a dated interface and occasional syncing issues. Some users report that sleep data fails to load or daily step counts require manual refreshes. App updates have improved stability, but it still lags behind polished competitors like Zepp or Fitbit.
Smart Assistant & Voice Control
This is one of the few areas where the Spade & Co Health Smartwatch 4 offers... nothing. There’s no Google Assistant, no Alexa, no proprietary voice commands — not even basic voice memo features. That’s a major trade-off compared to slightly pricier competitors like the Amazfit Bip 5 or older Galaxy Active models.
For buyers who don’t care about voice input, this may not be a dealbreaker. But if you're used to dictating messages, asking your watch about the weather, or controlling smart home devices by voice, this watch will feel like a step backward.
That said, given the watch’s sub-$100 MSRP and it being a fitness-centric watch, the omission is understandable. It’s built for health tracking and basic alerts — not as a productivity tool. The UI is entirely touch-based, with no side buttons or gesture controls either.
Bottom line: If voice control is important to you, you’ll need to shop higher up the chain.
Battery Life
Battery life is a highlight. Spade & Co claims 7 days of use, and most users report somewhere between 5 and 6 days of moderate usage per charge. That includes daily activity tracking, sleep monitoring, and receiving notifications. Heavier use — like long workouts or frequent syncing — might reduce that to 4 days, but that’s still miles ahead of similarly priced smartwatches with bright screens.
The included magnetic charger takes about 90 minutes to fully replenish the battery. There’s no fast charging or wireless support, but it’s a low-maintenance setup that most users found convenient and reliable.
Unlike many devices in the budget tier, battery performance on the Spade & Co Health Smartwatch 4 doesn't feel like a compromise. If anything, it's one of the key reasons to consider this device — particularly if you're upgrading from a tracker that needs near-daily charging.
Comfort & Design
Despite its low price, the Spade & Co Health Smartwatch 4 is surprisingly comfortable. It’s light enough to wear overnight, and the silicone strap feels soft out of the box — no break-in period required. Users consistently mentioned that they forgot they were even wearing it, especially during sleep or long walks.
The 1.85” display gives it a larger footprint than most basic fitness trackers, which may feel bulky on smaller wrists. However, the slim casing and smooth edges help offset this, and users found it well-balanced overall.
Design-wise, it looks like a hybrid between a Fitbit Versa and an Apple Watch clone — not revolutionary, but clean and modern. It’s available in several colors, and while build materials are plastic, it doesn't feel cheap or creaky.
Button-free operation makes the design look sleek, though some users wished for a physical back or home button. Still, the tap/swipe interface is intuitive and responsive.
Companion App & Ecosystem
The Spade Health companion app is functional but far from perfect. It handles syncing, data visualization, watch face selection, and basic settings. Users can view daily, weekly, and monthly graphs for heart rate, sleep, and steps — though the design can feel clunky or outdated.
Where it falls short is consistency. Multiple reviews mention occasional syncing delays, sleep data dropouts, or step counts that don't update in real time. Firmware updates have improved stability somewhat, but bugs remain.
Ecosystem-wise, there’s no integration with third-party services like Google Fit, Apple Health, Strava, or MyFitnessPal. What happens in the Spade app stays in the Spade app — which may be fine for casual users, but limits long-term tracking or data export options.
Customization is also limited: a few watch faces, no custom widgets, and no downloadable apps. It’s a closed ecosystem, and it shows — but for $99, it still covers the basics well enough for entry-level users.
Final Verdict
Spade & Co Health Smartwatch 4
The Spade & Co Health Smartwatch 4 is proof that you don’t need to spend a fortune to get meaningful health data and a capable smartwatch experience — at least for the basics. At just $99, it delivers strong core functionality like 24/7 heart rate tracking, surprisingly decent sleep monitoring, and reliable notification support. It’s comfortable enough to wear all day and night, and the battery lasts the better part of a week — something even $300+ smartwatches often struggle with.
But it’s important to set realistic expectations. This isn’t a “smartwatch” in the full app-store-and-voice-assistant sense. There’s no AI integration, no music streaming, no voice replies, and the app can be hit-or-miss depending on your phone. Fitness tracking is best suited for casual users, not competitive athletes or data obsessives.
That said, for someone looking to dip their toe into the world of health tracking — or upgrade from a basic step counter — this watch covers more ground than you’d expect for the price. It won’t replace a Fitbit Charge 6 or Apple Watch SE, but it doesn’t need to. It’s trying to be affordable, functional, and accessible — and on that front, it mostly succeeds.
💡 Best for: First-time smartwatch users, casual fitness fans, or anyone who wants sleep and health tracking without paying three figures.
