7 Best Fitness Tracker Watches Under $100 2026

This fitness tracker punches far above its price tag, delivering a rare blend of medical-grade health monitoring and rugged durability that’s hard to find under $100. With 24/7 dynamic heart rate, blood oxygen, blood pressure tracking, and temperature monitoring, it acts like a personal health sentinel on your wrist. The real showstopper? Its 5 ATM waterproof rating—a standout in this range—allowing swimmers to track laps, dive under water, or shower without hesitation, making it a top-tier choice for aquatic fitness lovers who want accurate data without breaking the bank.

In real-world testing, the 1.10-inch AMOLED HD touchscreen delivers crisp visuals even in sunlight, though the interface can feel slightly laggy when switching between apps. It reliably tracks steps, calories, and sleep stages—especially deep and light sleep cycles—and syncs smoothly with the “Keep Health” app, which organizes data into digestible charts. While it supports 25 sport modes, the lack of GPS means outdoor runners must carry their phone to map routes. Battery life impresses with 10–14 days of regular use, but the magnetic charging cable, while convenient, feels a bit flimsy over time.

Compared to basic IP68 models, this Zeacool tracker excels in water resilience and health depth, outperforming entry-level options that skimp on sensor accuracy. It’s ideal for swimmers, fitness newbies, and health-conscious users who want more than just step counting. Against the LIVIKEY or sub-$20 models, it trades some smart features for superior build quality and aquatic performance, offering a health-first experience with true swim-proof confidence.

For first-time buyers, the LIVIKEY Fitness Tracker is a no-fuss gateway into wearable wellness, offering solid core tracking at an unbeatable entry price. It nails the essentials: all-day heart rate monitoring, sleep stage analysis, and step tracking with enough accuracy to keep casual users informed. The IP68 waterproofing handles sweat, rain, and handwashing with ease, while smart notifications for calls, texts, and social apps ensure you stay connected—perfect for users who want a simple wrist companion without complexity.

During daily use, the tracker shines in consistency over sophistication. It logs steps and sleep patterns reliably, and the app allows setting custom step goals, helping build healthy habits. The 5–7 day battery life is decent, and a quick 2-hour charge gets you back up and running. However, the 9 sport modes feel limited compared to competitors, and while it tracks calories and distance, there’s no real-time feedback or advanced metrics during workouts. The screen, though responsive, lacks brightness adjustment, making outdoor visibility a struggle on sunny days.

When stacked against feature-rich models like the B0G1K8G8SS or Alexa-powered B0FWR9H9L9, the LIVIKEY doesn’t compete on specs—but it’s not meant to. It’s the ideal starter watch for teens, seniors, or budget-focused users who want dependable basics without clutter. For less than $20, it delivers essential fitness tracking with zero learning curve, making it a smarter buy than pricier but overcomplicated alternatives for light users who value simplicity and reliability.

If battery endurance and sport variety top your priority list, this 115-mode fitness tracker is a marathon runner, not a sprinter. It boasts 24/7 heart rate, blood oxygen, and blood pressure monitoring, giving users a comprehensive health snapshot right from the wrist. The 1.47-inch HD curved touchscreen is a visual upgrade over smaller rivals, offering crisp readability and smooth navigation, while the 150+ customizable watch faces add a personal touch that keeps the experience fresh. What truly sets it apart? A 10–12 day battery life on a single 2-hour charge, outlasting most competitors in heavy-use scenarios.

In real-world testing, the tracker excels at all-day activity logging, accurately capturing steps, distance, and calorie burn across multiple environments. The 115 sports modes—from yoga to rock climbing—make it a versatile companion for fitness enthusiasts exploring diverse workouts. When paired with your phone’s GPS, it maps outdoor runs with precision. However, the IP68 rating limits water exposure to showers and swimming, not prolonged submersion, which may disappoint serious swimmers. The sleep tracker provides detailed breakdowns of REM, light, and deep sleep, but occasional sync delays with the app can frustrate data-hungry users.

Against the Zeacool or Alexa-equipped Cillso model, this watch strikes a sweet balance between features and longevity, making it perfect for active users who hate daily charging. It lacks built-in voice assistants but compensates with broader sport tracking and superior uptime. For those who prioritize workout diversity and battery stamina over smart features, it delivers exceptional value with fewer compromises than most sub-$30 trackers.

Priced under $20, this fitness watch is a feature-packed powerhouse, redefining what’s possible at this budget level. It supports full Bluetooth calling—you can make, answer, and reject calls directly from your wrist, a rarity in this price bracket. Add in AI voice control for Siri, and you’ve got a hands-free assistant that manages alarms, music, and reminders with surprising clarity. The 1.85-inch HD touchscreen dominates the face, offering larger, clearer visuals than most rivals, and the 200+ customizable dials let you tailor the look to match any mood or outfit.

In practice, the 115+ sport modes cover everything from basketball to yoga, and the 3-axis gravity sensor delivers accurate step and calorie tracking throughout the day. The Da Fit app syncs data smoothly, though it lacks advanced health insights like sleep scores. Notifications for WhatsApp, Instagram, and email arrive instantly, but message replies aren’t supported, limiting interactivity. Battery life holds strong at 6–7 days, and the IP68 rating ensures it survives workouts, rain, and showers—though not swimming. The microphone quality is decent in quiet environments but struggles in windy or noisy areas.

Compared to the LIVIKEY or basic pedometers, this model delivers premium functionality at a budget price, making it the best bang-for-buck under $20. It’s ideal for young adults, students, or professionals who want calling, voice control, and fitness tracking in one sleek package. Against the B0FWR9H9L9 Alexa model, it trades Alexa for lower cost and bigger screen, offering more utility for less money—especially for iOS users who rely on Siri.

This Alexa-powered smartwatch is the complete package, earning its title as the best overall fitness tracker under $100 by blending smart convenience, health tracking, and rugged design into one seamless experience. The built-in Amazon Alexa is a game-changer—ask for weather, set timers, control smart home devices, or get news updates without touching your phone. Combined with Bluetooth 5.3 calling and message notifications, it keeps you connected like a mini smartphone on your wrist. The 1.83-inch HD display with 3D tempered glass is bright, scratch-resistant, and readable in direct sunlight, making it a pleasure to use outdoors.

Performance-wise, it tracks heart rate and sleep with high consistency, providing actionable insights through the VeryFit app. The 120+ sport modes cover nearly every activity, from swimming (despite IP68 limits) to hiking, and sensor accuracy during runs and gym sessions is impressive. However, GPS requires phone connection, and the watch isn’t suitable for swimming or hot showers, which may disappoint some users. Battery life delivers 5–7 days, and a 1.5-hour charge gets you back to full—fast, but not class-leading.

When compared to the B0G1K8G8SS or Zeacool models, this watch stands out with Alexa integration and superior smart features, making it perfect for tech-savvy users who want voice control and fitness tracking in one. It’s the most balanced option for daily drivers who value connectivity, health monitoring, and convenience. Against the B0FYHQ67VJ, it trades slightly shorter battery life for a smarter, more interactive experience—making it the ultimate all-rounder for under $30.

For users who treat their wrist like a health dashboard, this fitness tracker is the gold standard under $40, offering clinical-level monitoring with lifestyle smarts. Its 24/7 heart rate, blood pressure, and blood oxygen tracking deliver continuous health insights, helping detect irregularities before they escalate. The 1.58-inch ultra-high-resolution display is stunning for its class—vibrant, sharp, and always on, so you never need to tap to check time or vitals. With over 250 watch faces and customizable dials, it doubles as a fashion statement while maintaining serious functionality.

In real-world use, the 120+ sports modes track everything from cycling to Pilates with precision, and GPS route mapping via phone sync gives runners and hikers valuable feedback. The VeryFit app generates long-term health trends, making it easier to spot patterns in sleep or heart rate variability. It handles daily tasks flawlessly—water reminders, menstrual tracking, music control, and weather updates—but the microphone quality during calls is average, and Alexa or Google Assistant integration is missing. Battery life hits 6–12 days, though heavy GPS use cuts it down fast.

Against the Alexa-equipped B0FWR9H9L9 or the budget B0G59B4VR8, this model dominates in health depth and display quality, making it ideal for health-focused users, professionals, or older adults monitoring chronic conditions. It’s the only tracker in this list with lifetime customer support, adding peace of mind. For those willing to spend a bit more, it delivers the most complete health ecosystem under $50—outperforming rivals in metrics, design, and long-term reliability.

At just $13.99, this fitness tracker is a budget miracle, offering Bluetooth calling and health tracking at a price that feels like a steal. You can make and answer calls directly from your wrist, a feature typically reserved for much pricier models, and the built-in microphone and speaker deliver clear audio in quiet environments. It packs 24/7 heart rate, blood oxygen, and sleep monitoring, syncing data to your phone with reliable accuracy. The ultra-HD touchscreen is responsive, and with customizable watch faces, it feels more premium than its cost suggests—perfect for users who want smart features without spending a fortune.

In daily use, it tracks steps, calories, and sleep stages with decent precision, though the app lacks advanced analytics like sleep scores or heart rate variability. The IP68 waterproofing handles showers, sweat, and swimming, making it durable for active lifestyles. Battery life is strong—6–12 days per charge—and the magnetic charging is fast and convenient. However, the smart features are basic: no voice assistant, limited notification support, and no GPS. The calculator, flashlight, and find-phone functions add novelty but aren’t frequently used.

Compared to the LIVIKEY or even the B0G59B4VR8, this model offers the lowest entry point with calling capability, making it the best budget-friendly pick for cost-conscious buyers. It’s ideal for teens, seniors, or secondary device users who need call access and basic fitness tracking. Against the B0CS3GTYXZ, it delivers more functionality for less money—proving you don’t need to spend big to stay connected and active.
