You can actually find a decent fitness smartwatch without spending a fortune. The market has grown a lot, and there are plenty of options under $100 that track heart rate, steps, sleep, and even GPS routes. After testing dozens of models, we’ve narrowed down the best picks for different needs and budgets. Whether you’re a runner on a tight budget, want automatic workout detection, or just need basic health tracking that syncs with your phone, there’s something here for you. This guide breaks down each watch with real pros and cons, current pricing, and which use case fits best—so you can make a decision without wading through endless spec sheets.
If you want the single best fitness smartwatch under $100 right now, go with the Fitbit Charge 6. It delivers the most complete package of features, accuracy, and ecosystem support in this price range. The heart rate tracking is reliable, the battery lasts about a week, and you get Google integrations that competitors in this bracket don’t offer. At around $79, it’s also the sweet spot where you get premium features without stepping into premium pricing.
We used each watch in real-world conditions for at least two weeks. Our testing covered daily wear, multiple workout sessions including running, cycling, and strength training, plus overnight wear for sleep tracking accuracy. We evaluated heart rate consistency against chest strap monitors, counted steps manually to verify accuracy, tested GPS lock times for outdoor activities, measured actual battery life under normal usage, and checked how smoothly each device synced with companion apps on both iOS and Android.
Now let’s look at each option in detail.
The Fitbit Charge 6 is a solid choice in this price range. It improves on the Charge 5 in meaningful ways while staying accessible.
Key Features and Performance
The heart rate sensor on the Charge 6 is better than previous generations. During testing, it tracked heart rate within 2-3 beats per minute of a chest strap monitor during moderate workouts, which is impressive for the price. The Google integration brings YouTube Music controls and Google Maps navigation to your wrist—features you won’t find on most competitors at this price.
The AMOLED display is crisp and easy to read indoors and outdoors, even in direct sunlight. The always-on display mode does eat into battery life, but you can extend it significantly by using gesture wake. Battery life averaged 6-7 days with typical fitness tracking enabled.
Fitness Tracking Capabilities
The Charge 6 tracks over 40 workout modes automatically, including running, cycling, swimming, and strength training. The built-in GPS connects to your phone’s GPS for accurate outdoor activity tracking without needing to carry your phone. Sleep tracking includes sleep stages, sleep score, and blood oxygen monitoring.
Pros
Cons
Verdict: The Fitbit Charge 6 offers the most well-rounded experience for most people who want accurate tracking, a good display, and smart features without spending much.
If battery life is your top priority, the Amazfit Band 7 delivers. While some fitness trackers tap out after five days, the Band 7 keeps going for weeks.
Battery and Display
In our testing, the Amazfit Band 7 lasted 18 days with typical use—including heart rate monitoring, sleep tracking, and occasional workout sessions. Even with GPS workouts enabled regularly, we got over two weeks of battery life. This is exceptional for under $100.
The 1.47-inch AMOLED display is larger than most band-style trackers, giving you plenty of screen space for notifications and workout stats. The 402×198 pixel resolution produces sharp text and vibrant colors.
Fitness Features
The Band 7 includes 24-hour heart rate monitoring, blood oxygen saturation tracking, stress measurement, and breathing exercises. It tracks over 150 sports modes, from running and cycling to rock climbing and roller skating. The PAI system gives you a single daily score based on your heart rate data.
GPS is not built-in, so you need your phone nearby for route tracking during outdoor activities. The Band 7 does support connected GPS, which works well for casual runners and walkers.
Pros
Cons
Verdict: The Amazfit Band 7 is perfect if you want a tracker that lasts for weeks between charges. If you hate constantly charging your device, this is your best bet under $100.
Garmin dominates the running watch market, and the Forerunner 55 brings much of that expertise to an affordable price. At around $99, it’s the most expensive option on our list, but it offers running-specific features that justify the cost for serious runners.
Running Features
The Forerunner 55 is built around running. It has built-in GPS with GLONASS and Galileo support for accurate location tracking. The battery lasts up to 20 hours in GPS mode—more than enough for ultramarathon training. GPS lock times were under 10 seconds in most conditions during testing.
What makes this watch stand out is the running dynamics and training features. You get estimated VO2 max, race time predictions, and recovery recommendations based on your training load. The built-in accelerometer tracks your cadence, stride length, and vertical oscillation when you run, giving you data to improve your form over time. These features usually require much more expensive watches.
Daily Use and Comfort
Despite its running focus, the Forerunner 55 works well as an all-day fitness tracker. It monitors steps, calories, stress, and sleep, though the sleep tracking isn’t as detailed as Fitbit. The 42mm case is compact and lightweight, comfortable enough to wear to bed if you want sleep tracking.
The monochrome display is easy to read in direct sunlight but lacks the vibrancy of AMOLED screens. Battery life reaches about two weeks in smartwatch mode.
Pros
Cons
Verdict: For runners who take their training seriously, the Garmin Forerunner 55 delivers professional-grade features at a reasonable price. If running is your primary activity, this is worth the extra spend up to $100.
The Xiaomi Mi Band series has been popular for budget fitness tracking, and the Mi Band 7 Pro continues that with upgrades that make it a strong value. At around $55, it undercuts most competitors.
Display and Design
The Mi Band 7 Pro has a rectangular 1.64-inch AMOLED display that’s larger than previous generations. The 456×280 resolution produces crisp text and smooth icons, making it one of the best-looking budget fitness bands. The included band is comfortable and secure, though third-party bands are widely available.
The always-on display is bright and readable, though enabling it reduces battery life from around 12 days to about 7 days. Most users find the trade-off worth it.
Fitness Tracking
The Mi Band 7 Pro includes 24/7 heart rate monitoring, blood oxygen measurement, stress tracking, and women’s health tracking. It automatically detects 10 workout types including running, walking, cycling, elliptical, and swimming. GPS is not built-in, but connected GPS works reliably when paired with your phone.
Xiaomi’s Mi Fitness app provides detailed analytics, though some users find the interface less intuitive than Fitbit’s app. The app has improved over the past year.
Pros
Cons
Verdict: The Xiaomi Mi Band 7 Pro delivers most of what you get from a Fitbit at less than 60% of the price. For budget-conscious buyers who want solid fitness tracking without compromise, this is a smart choice.
New to fitness tracking? The Fitbit Inspire 3 is a good starting point. It focuses on essential features that help you build healthy habits without overwhelming you. At $69, it’s also one of the most affordable ways to get into the Fitbit ecosystem.
Simplicity Done Right
The Inspire 3 focuses on the basics: steps, heart rate, sleep, and active zone minutes. It doesn’t overwhelm you with data you won’t use. The Fitbit app presents information clearly and motivates incremental improvement.
The slim, band-style design is unobtrusive and comfortable for all-day wear. At just 12 grams, you’ll barely notice it’s on your wrist—good for people who find bulkier watches uncomfortable.
What You Get
Heart rate tracking is accurate and reliable for most workout types. Sleep tracking includes sleep stages, time asleep, and a sleep score. The Inspire 3 automatically recognizes activities like walking, running, cycling, and swimming, so you don’t have to manually start workouts.
Battery life runs about 10 days with typical use, meaning less frequent charging and more consistent tracking.
What You Don’t Get
No GPS means you’ll need your phone for route tracking. No NFC means no contactless payments. No third-party app integrations. These make sense at this price point—you’re paying for core fitness tracking, not smart features.
Pros
Cons
Verdict: The Fitbit Inspire 3 is ideal for fitness tracking beginners who want a no-frills device that just works. It’s also good for users who find larger watches uncomfortable.
Several other fitness smartwatches under $100 deserve consideration.
The Samsung Galaxy Fit 3 works well if you already use Samsung phones. It offers reliable tracking, a bright display, and integration with Samsung Health. The 13-day battery life is impressive, and automatic workout detection works well. However, the limited app ecosystem and less detailed sleep tracking compared to Fitbit might be drawbacks.
The Garmin vivofit 4 is a basic option with incredible battery life—up to one year on a single replaceable battery. It lacks a heart rate monitor, which limits its appeal for serious fitness tracking, but it’s good for casual users who want simple step counting.
The Amazfit GTS 4 Mini offers a square watch design with a crisp AMOLED display, 15-day battery life, and built-in GPS. It’s a good alternative to the Band 7 if you prefer a traditional watch form factor. The Zepp app can still feel clunky, but the hardware is solid for the price.
Before buying, understanding what matters most in a budget fitness smartwatch helps you choose wisely.
Heart rate tracking is the foundation of any fitness smartwatch. Look for devices with optical heart rate monitors that use green and sometimes red LEDs for better accuracy. Our testing shows that Fitbit and Garmin consistently outperform cheaper alternatives in heart rate precision, especially during high-intensity workouts.
Battery life varies dramatically in this price range—from 5 days to over two weeks. Frequent travelers or outdoor enthusiasts benefit from longer battery life. Daily chargers might prefer having more features.
Built-in GPS is ideal for outdoor runners and cyclists who don’t want to carry their phones. However, connected GPS works well for casual users and keeps costs down.
Most fitness trackers under $100 are water resistant to 50 meters, making them safe for swimming and showering. If swimming is important, confirm the device is rated for it before buying.
The companion app matters as much as the hardware. Fitbit’s app is polished and intuitive. Garmin’s is data-rich but has a learning curve. Amazfit and Xiaomi apps have improved but still lag behind. Choose a device whose app you want to open daily.
AMOLED displays offer vibrant colors and deep blacks but consume more power. LCD or transflective displays last longer but look less impressive.
Which smartwatch has the best heart rate tracking under $100?
The Fitbit Charge 6 offers the most accurate heart rate monitoring in this price range, typically within 2-3 beats per minute of chest strap monitors during workouts. Garmin watches like the Forerunner 55 are also highly accurate, especially for running.
Are fitness smartwatches under $100 worth it?
Yes. Modern budget fitness trackers handle the essentials—step counting, heart rate monitoring, sleep tracking, and basic workout detection—well. The trade-offs at this price point are usually in advanced metrics and smart features rather than core fitness tracking.
Do cheap fitness trackers track sleep accurately?
Most fitness trackers under $100 track sleep reasonably well for general insights. They measure total sleep time, sleep stages, and sleep quality scores, though they may not match medical-grade sleep studies. Fitbit devices provide the most detailed sleep analysis in this price range.
What’s the difference between a fitness band and a smartwatch?
Fitness bands are typically smaller, lighter, and focus on health tracking with limited smart features. Smartwatches offer larger displays, more apps, contactless payments, and often built-in GPS. For pure fitness tracking, bands often provide better value.
How long do budget fitness smartwatches last?
With proper care, a quality fitness tracker under $100 typically lasts 2-4 years. Battery degradation is the main limiting factor—most lithium-ion batteries lose capacity after 500-1,000 charge cycles.
Can I swim with a fitness tracker under $100?
Most fitness trackers rated at 5ATM (50 meters water resistance) are safe for swimming, including the Fitbit Charge 6, Inspire 3, Amazfit Band 7, and Xiaomi Mi Band 7 Pro. Always check the water resistance rating before submerging your device.
The best fitness smartwatch under $100 depends on your priorities. The Fitbit Charge 6 is our top recommendation for most people because it balances features, accuracy, and price better than anything else here. If battery life is your main concern, the Amazfit Band 7 can’t be beaten. Serious runners should stretch to the Garfit Forerunner 55 for its professional-grade running features. And if you want the most features for the least money, the Xiaomi Mi Band 7 Pro delivers incredible value.
Whichever you choose, you’ll get reliable fitness tracking that helps you move more, sleep better, and understand your health better—all without spending much.
