6 Best Smart Rings and Fitness Trackers Under $100 in 2026
Smart rings and fitness trackers have become one of the most affordable ways to keep tabs on heart rate, sleep, blood oxygen and daily activity without committing to an expensive smartwatch ecosystem. This guide rounds up six options that all sell for under $100, ranging from full-featured fitness watches to discreet, lightweight rings.
It is built for shoppers who want a clear, side-by-side look at what each device actually offers, how customers who bought them have rated them, and how many people have left feedback. Every product below is drawn from real catalog listings, and every claim about features, pricing and ratings comes directly from that listing data rather than hands-on testing.
#1 — Our Top Pick
Smart Watch Fitness Tracker with 24/7 Heart Rate, Blood Oxygen Blood Pressure Monitor Sleep Tracker 120 Sports Modes Activity Trackers Step Calorie Counter IP68 Waterproof for Andriod iPhone Women Men
★ 5 (88)
Smart Watch Fitness Tracker with 24/7 Heart Rate, Blood Oxygen Blood Pressure Monitor Sleep Tracker 120 Sports Modes Activity Trackers Step Calorie Counter IP68 Waterproof for Andriod iPhone Women Men
This smartwatch tops the list by combining a perfect 5 out of 5 rating with one of the broadest feature sets on this page: 24/7 heart rate, blood oxygen, blood pressure, sleep tracking and 120 sport modes, all in an IP68 waterproof build for under $90. Its 88 reviews are a smaller sample than some of the ring competitors further down this list, so the rating should be read as a strong but still relatively early track record rather than a long-proven one. Even so, the combination of a flawless average and a genuinely feature-dense package is what earns it the top spot ahead of cheaper, more minimal ring options.
The Bestinn Smart Watch Fitness Tracker lands at the top of this list for a straightforward reason: it pairs a perfect 5 out of 5 customer rating with the most comprehensive feature list of any product in this roundup, including 24/7 heart rate monitoring, blood oxygen tracking, blood pressure readings, sleep tracking and 120 distinct sport modes, all backed by IP68 waterproofing. For shoppers who want a single device to cover the full spread of everyday health metrics rather than piecing together functionality from a smaller ring, this breadth of features at an $89.99 price point is hard to match on this list.
It is worth noting that the 5.0 average comes from 88 reviews, a reasonable but still modest sample compared to the 367 reviews behind the WEYATO ring further down this list. That does not undermine the rating, but it does mean the evidence is somewhat newer. The pairing of a flawless score with an unusually complete feature set is ultimately what separates it from the more pared-down, lower-priced ring alternatives, making it the strongest overall pick for buyers who want maximum tracking capability for under $100.
- + Perfect 5.0 average rating
- + Tracks heart rate, blood oxygen and blood pressure in one device
- + 120 sport modes and IP68 waterproofing for varied activities
- + Full smartwatch form factor compatible with Android and iPhone
#2
Smart Health Ring Fitness Tracker for Men Women, New RG 8The Milavan RG 8 ring matches the top product's perfect 5.0 rating while costing less than half as much at $43.99, making it the most budget-friendly 5-star option on this list. Its 80 reviews are fewer than the WEYATO ring ranked just below it, but the combination of a top rating and the lowest price among the 5.0-rated products is what pushes it ahead of that higher-review-count competitor.
#3
Women Men Smart Ring Health Tracker, Sleep Exercise Health Monitoring Wearable Device, IP68 Waterproof, iOS/Android Compatible, No Subscription Required, 5‑Day Long Lasting Battery (Rose Gold, 8)With 367 reviews at a perfect 5.0 average, the WEYATO ring has by far the largest review base of any product on this list, which is a meaningful signal of broad adoption. It lands at #3 rather than higher because it costs slightly more than the Milavan ring above it and its listing describes tracking in more general terms, without specifically calling out blood oxygen or blood pressure monitoring.
#4
Smart Bracelet, Health Fitness & Activity Tracker with All-Day Continuous Heart Rate/Blood Pressure Monitor, Sleep Tracker, 170+ Sport Modes, 60 Day Battery & Free App, IP68 Smart Band for Android IOSThe PJIVE smart bracelet brings a long feature list — continuous heart rate and blood pressure monitoring, sleep tracking, 170+ sport modes and a 60-day battery — at a mid-range $66.48 price point. Its 4.8 rating across 262 reviews is slightly below the perfect scores of the top three products, which is why it ranks fourth despite the strong feature set.
#5
Smart Ring for Women Men, Fitness Ring with Heart Rate, Blood Oxygen,Stress, Sleep Tracker, Step Tracker, Fit Ring No Subscription Fee, IP68 Waterproof Smart Ring for iPhone & Android (Rose Gold, 6#)The REWSX ring lists a strong feature set for its price — heart rate, blood oxygen, stress and sleep tracking with no subscription fee — and carries a solid 4.8 rating. Its 41 reviews, however, are the smallest sample on this list, so that rating should be read as a modest early signal rather than a thoroughly proven track record, which is why it ranks fifth.
#6
Fitness Tracker, Smart Watches for Women Men with 24/7 Heart Rate/Blood Pressure/Blood Oxygen Monitor, Sleep Tracker, Calories&Step Counter, IP68 Waterproof Health Activity Trackers for Android&iPhoneThe RLQA fitness tracker offers a comprehensive feature set — 24/7 heart rate, blood pressure and blood oxygen monitoring plus sleep and step tracking — and a solid 4.9 rating across 153 reviews. It ranks last mainly because, at $99.99, it sits right at the top of the under-$100 range covered by this guide, making it the least cost-competitive option relative to similarly equipped products above it.
How we selected these products
This list was built by comparing publicly listed customer ratings, the number of reviews behind each rating, the current price, and the features each brand actually lists on its product page. A high star rating backed by only a handful of reviews is treated differently than the same rating backed by hundreds, since a larger review base generally gives a clearer picture of how a product performs across many different buyers.
Price was weighed against what each device includes out of the box — for example, whether it tracks blood pressure in addition to heart rate, how many sport modes it supports, and whether it requires a subscription. No products were purchased or tested firsthand for this guide; the rankings reflect research into existing listing data, ratings and review volume rather than personal use.
How to Choose a Smart Ring or Fitness Tracker Under $100
Budget wearables in this price range can vary a lot in both form factor and feature depth, so it helps to think through a few practical questions before choosing one.
- Form factor: Rings are smaller and more discreet, and often advertise longer battery life relative to their size, but they typically have no screen and rely entirely on a companion app. Watches and bracelets usually offer a display and can pack in more sensors, at the cost of being bulkier on the wrist.
- Tracked metrics: Check the listing carefully for exactly which metrics are tracked. Heart rate and step counting are standard, but blood oxygen, blood pressure and stress tracking are not always included, even on similarly priced products.
- Subscription requirements: Some wearables require an app subscription to unlock full tracking history or advanced features. If ongoing cost matters to you, look for listings that explicitly state no subscription is required.
- Rating versus review count: A 5.0 average built on a small number of reviews is weaker evidence than a slightly lower rating backed by hundreds of reviews. Consider both numbers together rather than the star rating alone.
- Battery life and waterproofing: If you plan to wear the device during workouts or swimming, confirm the IP rating, and check the advertised battery life if you don't want to charge it frequently.
FAQ
- Are smart rings as accurate as fitness watches for heart rate and sleep tracking?
- Listings for both rings and watches in this category typically advertise similar sensor-based tracking for heart rate, sleep and activity. Accuracy can vary by brand and individual fit, so it's worth checking a product's specific listed features and customer rating rather than assuming all rings or all watches perform identically.
- Do I need a subscription to use these fitness trackers?
- Not necessarily. Several products in this list, including the WEYATO and REWSX rings, explicitly advertise no subscription requirement. Always check the individual listing, since subscription requirements can vary even within the same product category.
- Is a higher review count more important than a higher star rating?
- Both matter, but a very high rating from only a handful of reviews is weaker evidence than a slightly lower rating backed by hundreds of reviews. A large review count generally gives a clearer picture of how a product performs across a wide range of buyers.
- What's the main trade-off between a smart ring and a fitness watch under $100?
- Rings tend to be smaller, lighter and less visible, but they typically lack a screen and may list fewer tracked metrics. Watches and bracelets usually display more information at a glance and often support more sport modes, but are bulkier to wear all day.
- Does IP68 waterproofing mean I can swim with these devices?
- IP68 generally indicates strong resistance to dust and water immersion, but exact swim-safety depends on the manufacturer's specific guidance. Check the individual product listing or manufacturer instructions before swimming or showering with any wearable.
Each of these six products covers the core fitness-tracking basics — heart rate, sleep and activity — at a price under $100, with differences showing up mainly in form factor, extra sensors like blood pressure or blood oxygen, battery life, and how many customers have reviewed them so far. The Bestinn Smart Watch leads this list for combining a perfect rating with the broadest feature set, while the ring options from Milavan, WEYATO and REWSX offer lighter, more discreet alternatives at lower price points. Matching the right pick to your needs ultimately comes down to how much you value a screen and extra sensors versus a smaller, simpler everyday wearable.
