best Smart watch under $100
Amazfit Bip 6
| MODEL | Display | Battery life | GPS | Water resistance | Compatibility | Sports modes |
| Amazfit Bip 6 | 1.97″ AMOLED | 14 days | built in | 5ATM | Android and iOS | 120 + |
The Amazfit Bip 6 is one of the most remarkable deals in the wearables market right now. At $79, it ships with a huge 1.97-inch AMOLED display (sharper than you’d expect at this price), built-in GPS, a 14-day battery life, sleep and stress tracking, and over 120 sports modes. You get a lot of watches for the money.
What makes the Bip 6 compelling as a value pick over the Active 2 is simply the price gap. If you don’t need NFC payments or offline music storage, you’re saving $35 while still getting GPS and that stunning screen. Sleep staging and stress monitoring work reliably, and smart notifications arrive without lag.
The companion Zepp app is one of the better ones in this category, delivering detailed charts and health insights that are easy to understand at a glance.

Amazfit Active 2 — ~$99
| MODEL | Display | Battery life | GPS | Water resistance | Compatibility | Key Extras |
| Amazfit Active 2 | 1.75″ AMOLED | 10 days | built in | 5ATM | Android and iOS | NFC, Music Storage |
Tom’s Guide named the Amazfit Active 2 the best cheap smartwatch of 2026, and it’s easy to see why. For right at $99, you get a gorgeous, bright AMOLED display, onboard GPS (no phone required on your run), 160+ sports and exercise profiles, NFC for tap-to-pay, and 4GB of storage for offline music. It genuinely does things many $200 watches don’t.
The design is slim and attractive — more like a fashion accessory than a fitness band — and it sits comfortably through the night for sleep tracking. Battery life runs about 10 days in typical use, which is excellent. The Zepp OS isn’t quite as polished as Apple’s watchOS or Wear OS, and the heart rate and elevation data can occasionally drift, but those are the only caveats at this price.
If you’re on Android or iPhone and want one watch that handles everything — fitness, smartwatch features, GPS, payments — the Active 2 is the undisputed champion under $100.

SAMSUNG Galaxy FIT 3 — ~$42
| MODEL | Display | Battery life | GPS | Water resistance | Compatibility | Key Extras |
| SAMSUNG Galaxy FIT 3 | 1.6″ AMOLED | 14 days | No GPS | IP68 | Android only | Sp02, Heart rate |
Samsung’s Galaxy Fit 3 arrived in early 2025 and immediately became one of the most exciting budget trackers on the market. At around $55, it offers a surprisingly large and vivid 1.6-inch sAMOLED display, over 100 workout tracking modes, fall detection (a safety feature usually reserved for premium devices), SpO2 monitoring, and detailed sleep analysis borrowed directly from the Galaxy Watch series.
The big catch: the Galaxy Fit 3 is Android-only. If you’re pairing it with a Samsung Galaxy phone, the experience is even smoother — data flows seamlessly into Samsung Health, and you benefit from tight ecosystem integration. iPhone users should look elsewhere.
At this price, the Galaxy Fit 3 is arguably the best-looking budget fitness tracker available, with a refined aluminium chassis that doesn’t feel cheap in hand or on the wrist.

XIAOMI Mi Smart Band 10
| MODEL | Display | Battery life | GPS | Water resistance | Compatibility | Key Extras |
| XIAOMI Mi Smart Band 10 | 1.72″ AMOLED | 21 days | No GPS | 5ATM | Android | 150+ Sports mode |
If you’re working with a tighter budget, the Xiaomi Mi Band 10 is almost absurdly good value. At around $40, it delivers an AMOLED color touchscreen, 20-day battery life on a single charge, 24/7 heart rate monitoring, SpO2 tracking, detailed sleep analysis, and swim-proof 5ATM water resistance. It supports 30+ exercise types and pairs with both Android and iPhone.
Xiaomi’s Mi Fitness app (formerly Mi Fit) is reliable and gives you clear charts covering sleep quality, heart rate trends, and step counts. The sleep tracking in particular is a standout — it uses a complex algorithm combining heart rate, body temperature, and movement to give you genuinely useful breakdowns of deep vs. light sleep.
The trade-off, as with many sub-$50 trackers, is no built-in GPS. But for the price, nothing comes close.
