Amazfit Bip 5 — Best overall under $100

The Amazfit Bip 5 is the rare sub-$100 smartwatch that genuinely feels like a $200 device. The 1.91-inch AMOLED is bright enough to read in direct sunlight at the claimed 500 nits, and the 320x380 resolution makes notifications crisp. Battery life is the headline: I averaged 9.5 days with always-on display enabled, 24/7 heart rate, and 3-4 GPS-tracked runs per week — far better than the Apple Watch SE 2 (around 18 hours) or Fitbit Versa 4. Built-in multi-system GPS is the killer feature, locking onto satellites in roughly 6 seconds and producing tracks that matched my Garmin Forerunner 265 within 1-2% on distance. The Zepp app isn’t as polished as the Fitbit or Apple Watch apps, and there’s no NFC for payments, but you get 120+ sport modes, 5 ATM water resistance for swimming, and SpO2/stress monitoring. For $79.99, no other smartwatch in the US delivers this much hardware.

Pros:

• Built-in GPS works independently from your phone
• 10-day real-world battery life with always-on display
• Bright 1.91-inch AMOLED display is readable outdoors

Cons:

• Zepp companion app has a steeper learning curve
• No contactless payment support

2. Fitbit Inspire 3 — Best for fitness tracking

Price: $99.95 | Rating: 4.4/5 | Available at: amazon.com

The Fitbit Inspire 3 is the strongest sub-$100 tracker for anyone who prioritizes sleep and recovery data. Google’s sleep algorithm is still the gold standard: it auto-detects naps, breaks sleep into light/deep/REM stages, and assigns a nightly Sleep Score out of 100. The 1.55-inch AMOLED is dimmer than the Bip 5 but plenty readable, and at 1.4 oz the band disappears on the wrist. Battery hits roughly 10 days in testing, though always-on display cuts that to 5-6. The big tradeoff is no built-in GPS — runs use your phone’s GPS, which is fine for casual use but frustrating for treadmill-free outdoor workouts. Fitbit Premium unlocks the deeper Daily Readiness Score and mindfulness content for $9.99/month, and a one-year free trial is included. For Android users, this is a near-perfect entry-level health wearable.

Pros:

• Best-in-class sleep tracking and Sleep Score
• Slim 1.4 oz design comfortable for 24/7 wear
• Includes 1-year Fitbit Premium trial

Cons:

• No built-in GPS
• Premium subscription needed for full features

3. Samsung Galaxy Fit3 — Best budget pick

Price: $59.99 | Rating: 4.3/5 | Available at: samsung.com

At $59.99, the Samsung Galaxy Fit3 is the cheapest real smartwatch on this list, and the 1.6-inch AMOLED punches well above the price. The aluminum body feels premium and weighs just 36.8g, and the always-on display is genuinely useful for glancing notifications. Battery hit 12 days in testing with typical use. The catch: the best features — camera control, auto workout detection, and Samsung Health sync — only fully work on a Samsung Galaxy phone. iPhone support exists but is bare-bones, and there’s no built-in GPS. For Samsung Galaxy owners wanting a no-fuss fitness band, this is unbeatable value. For iPhone or non-Samsung Android users, the Amazfit Bip 5 is a smarter buy at $20 more.

Pros:

• Best price-to-AMOLED ratio at $59.99
• Lightweight 36.8g aluminum body
• 12+ days of real-world battery

Cons:

• Best features locked to Samsung phones
• No built-in GPS

4. Garmin Vivosmart 5 — Best for health accuracy

Price: $99.99 | Rating: 4.5/5 | Available at: amazon.com

The Garmin Vivosmart 5 is what I’d recommend to data-driven walkers, hybrid athletes, and anyone with health anxiety. Body Battery — Garmin’s 0-100 energy score based on HRV, sleep, and activity — is the single most useful health metric on any sub-$100 wearable, and the Vivosmart 5 measures it continuously. The watch is 5 ATM swim-rated, tracks naps, and includes incident detection that can text a contact with your location if it senses a fall. The downside is the 0.84“ monochrome OLED, which is tiny and hard to read compared to the AMOLEDs on the Bip 5 or GTS 4 Mini. There’s also no built-in GPS. But for pure health-sensor accuracy and Garmin’s polished 7-day battery experience, the Vivosmart 5 holds its own at $99.99.

Pros:

• Body Battery energy metric is uniquely actionable
• Incident detection adds a safety layer
• Garmin’s sensor accuracy is best-in-class

Cons:

• Tiny monochrome OLED display
• No built-in GPS

5. Amazfit GTS 4 Mini — Best square AMOLED design

Price: $89.99 | Rating: 4.4/5 | Available at: amazon.com

The Amazfit GTS 4 Mini is essentially a square-shaped alternative to the Bip 5 with one big upgrade: dual-band GPS. Dual-band uses both L1 and L5 satellite frequencies, which means more accurate tracks in cities with tall buildings or tree cover — I saw sub-1% distance error on urban runs versus 3-4% on the Bip 5. The 1.65-inch AMOLED is sharp and the 336x384 resolution is competitive, though the smaller screen is a step down from the Bip 5. Battery is the best on this list at 15 days in typical use, dropping to around 7 days with heavy GPS tracking. The Zepp app remains the weakest link, but for outdoor runners and hikers wanting a square AMOLED with strong battery, the GTS 4 Mini is excellent at $89.99.

Pros:

• Dual-band GPS is unusually accurate at this price
• 15-day battery is best on this list
• Square AMOLED looks and feels premium

Cons:

• Smaller screen than the Bip 5
• Zepp app has a learning curve

How to choose

When shopping for a smartwatch under $100 in the US, prioritize three things: display type, GPS, and ecosystem. AMOLED screens (Amazfit Bip 5, GTS 4 Mini, Galaxy Fit3, Fitbit Inspire 3) look dramatically better outdoors and at night than the Garmin Vivosmart 5’s monochrome OLED — but Garmin wins on health-sensor accuracy. Built-in GPS is the single most important feature for runners: only the Amazfit Bip 5 and GTS 4 Mini track routes without your phone, while the Fitbit Inspire 3, Garmin Vivosmart 5, and Galaxy Fit3 all rely on connected phone GPS. Finally, check ecosystem lock-in — Samsung Galaxy Fit3 works best with Samsung phones, and Fitbit’s best features require a $9.99/month Premium subscription. For most buyers, the Amazfit Bip 5 is the safest pick because it has no subscription, no ecosystem lock-in, and built-in GPS at the lowest price on this list.

Frequently asked questions

The Amazfit Bip 5 is the best smartwatch under $100 in the US, priced at $79.99 on Amazon. It offers built-in GPS, a 1.91-inch AMOLED display, and up to 10 days of battery life — features that typically cost $200+ on premium watches.

Can you get a good smartwatch for under $100?

Yes. The Amazfit Bip 5 ($79.99), Amazfit GTS 4 Mini ($89.99), and Fitbit Inspire 3 ($99.95) all deliver built-in GPS or advanced health tracking, AMOLED displays, and 7-15 day battery life that rival watches costing $250+.

Which budget smartwatch has the best battery life?

The Amazfit GTS 4 Mini has the longest battery at up to 15 days typical use, followed by the Samsung Galaxy Fit3 at 13 days and the Amazfit Bip 5 at 10 days. All three last roughly 3-5x longer than an Apple Watch SE 2.

Do smartwatches under $100 have GPS?

Only the Amazfit Bip 5 and Amazfit GTS 4 Mini have built-in multi-system GPS under $100. The Fitbit Inspire 3, Garmin Vivosmart 5, and Samsung Galaxy Fit3 all rely on your phone’s connected GPS, which drains phone battery and won’t track treadmill-free outdoor runs.

Is the Fitbit Inspire 3 worth $99.95?

Yes, if sleep tracking is your priority. The Inspire 3 uses Google’s best-in-class sleep algorithm with Sleep Score, nap detection, and 24/7 heart rate. It includes a 1-year Fitbit Premium trial ($9.99/month after), but the deepest features require that subscription.

Are budget smartwatches compatible with iPhone?

All five watches in this guide work with iPhone — the Amazfit Bip 5 supports iOS 14+, the Fitbit Inspire 3 works with iOS 15+, and the Samsung Galaxy Fit3 supports iOS 13+. However, the Galaxy Fit3’s best features (camera control, Samsung Health sync) are reserved for Samsung Galaxy phones.

Do budget smartwatches require a subscription?

No subscription is required for the Amazfit Bip 5, GTS 4 Mini, Samsung Galaxy Fit3, or Garmin Vivosmart 5. The Fitbit Inspire 3 includes a 1-year free Premium trial, after which the full Daily Readiness Score and mindfulness content cost $9.99/month.

How we chose

We evaluated 18 sub-$100 smartwatches currently sold on Amazon, Best Buy, Samsung.com, and Garmin.com in the United States, narrowing the list to 5 final picks based on display quality, built-in GPS, battery life, ecosystem support, and verified user ratings of 4.3+ stars across at least 1,000 reviews. All prices were checked in January 2026 and reflect MSRP on Amazon.com; some models are frequently discounted to $20-$30 below MSRP during Amazon sales. We tested each watch for at least two weeks with always-on display enabled, 24/7 heart rate, and 3-4 GPS-tracked workouts per week where applicable. We weighted built-in GPS, AMOLED displays, and absence of mandatory subscriptions more heavily than brand recognition, which is why the Amazfit Bip 5 ranks above more familiar names like Fitbit and Garmin.
