For most people, the Fitbit Inspire 3 is the best fitness tracker under $100. It is slim, comfortable, works with Android and iPhone, tracks everyday wellness and sleep well, and avoids the distractions of a full smartwatch. If you need phone-free GPS, choose the Amazfit Bip 6 instead. Samsung phone owners should consider the Galaxy Fit3, while the Amazfit Active 2 offers the most ambitious training feature set at the top of the budget.
This ranking is for U.S. shoppers using a strict device-price limit of $100 before tax. Prices and stock were checked on August 11, 2026, but promotions and availability can change. The CMF Watch Pro 2 is included as a conditional pick because its official U.S. page was sold out at the time of verification.
Best fitness trackers under $100 at a glance
| Tracker | Checked U.S. price | Built-in GPS | Battery claim | Phone compatibility | Best for |
|---|---|---|---|---|---|
| Fitbit Inspire 3 | $79.95 promotional price; $99.95 regular price | No | Up to 10 days | Android and iOS | Everyday wellness and sleep |

Battery figures are manufacturer “up to” claims rather than guaranteed runtimes. GPS, frequent notifications, calls, always-on display settings, and workout recording can reduce battery life.

The ranking weighs current U.S. pricing, official specifications, independent buying guidance where available, phone compatibility, GPS capability, battery claims, and the practical experience each device is designed to provide. A fitness tracker under $100 normally covers steps, heart rate, sleep, workouts, and notifications. The biggest dividing line is GPS: some models can record an outdoor route without relying on a phone, while others use the phone’s GPS or do not provide route tracking on their own.

“Under $100” means the device itself must be priced at $100 or less before sales tax. The standard Amazfit Active 2 Round qualifies at $99.99; the more expensive premium version does not. A temporary sale price may qualify a product today but should not be treated as permanent.
1. Fitbit Inspire 3 — Best overall for everyday wellness
Checked price: $79.95 at the Google Store promotional price, with a listed regular price of $99.95. Recheck the current price before buying.

If you want the safest all-around choice, start with the Fitbit Inspire 3. It is the most focused tracker here: a narrow band with a small color AMOLED display, dependable core wellness features, and fewer smartwatch distractions than the larger watch-style alternatives.
The Inspire 3 tracks heart rate, sleep, steps, workouts, and notifications. It can automatically recognize some exercises, is rated for 5 ATM water resistance, and is claimed to last up to 10 days per charge. Compatibility with both Android and iOS makes it the least restrictive recommendation for households that use different phone platforms.
Why the Inspire 3 ranks first
- Comfortable everyday design: Its slim band format is better suited to sleeping and continuous wear than a larger watch for many users.
- Strong wellness focus: It covers the essentials without trying to replace a smartwatch.
- Broad compatibility: It works with Android phones and iPhones.
- Good battery claim: Up to 10 days is competitive for a small tracker.
- Water resistance: Its 5 ATM rating is more reassuring for normal water exposure than the IP68-only CMF alternative.
What it does not do
The Inspire 3 has no onboard GPS. It can use a paired phone for GPS-based outdoor route, distance, and pace tracking, but it cannot independently record a route when you leave the phone behind. That is the main reason runners and cyclists may prefer the Amazfit Bip 6 or Active 2.
The display is also small. It is useful for quick glances, but a larger watch-style tracker is easier for viewing maps, workout statistics, and notifications during exercise. Some more advanced Fitbit and Google Health insights may also depend on optional premium services, so buyers should distinguish the core tracking functions from subscription-based extras.

2. Amazfit Bip 6 — Best budget tracker with built-in GPS
Checked price: $79.99 announced U.S. price, with U.S. availability announced through Amazfit.com and Amazon.
The Amazfit Bip 6 is the clear choice when built-in GPS matters more than having the simplest companion app. It delivers phone-free route recording, a large display, and a long battery claim at a price below the budget ceiling.
Its 1.97-inch AMOLED screen is much larger than the Inspire 3’s display. The Bip 6 includes onboard GPS, offline maps, more than 140 workout modes, heart-rate monitoring, blood-oxygen monitoring, sleep tracking, notifications, and 5 ATM water resistance. Amazfit claims up to 14 days of battery life, although GPS-heavy use will generally require more frequent charging.
Why it is the best GPS value
- Built-in GPS: It can record outdoor routes without requiring the phone to provide the GPS signal.
- Offline maps: The mapping feature is unusual at this price.
- Large AMOLED display: Better for workout data and watch-style interactions.
- Wide workout coverage: More than 140 workout modes provide plenty of activity options.
- Long battery claim: Up to 14 days is the strongest claim among the five ranked devices.
Trade-offs
The Bip 6 lacks NFC payments and does not offer as many third-party smartwatch capabilities as a full smartwatch. Independent reviewers have also described the Zepp companion app as less polished than Fitbit’s app. The large watch-style body may be less discreet than a slim band, particularly for sleep tracking or smaller wrists.

Built-in GPS does not mean the watch never needs a phone. You will still typically use a phone for setup, syncing, notifications, software updates, and reviewing a full activity history. It does mean you can leave the phone behind for a GPS workout and record the route on the watch.
Choose it if: you run, walk, hike, or cycle outdoors and want GPS without carrying your phone. Skip it if: you value Fitbit’s simpler wellness experience or want contactless payments and a broad smartwatch app ecosystem.
3. Samsung Galaxy Fit3 — Best for Samsung Android users
Price reference: Samsung announced a U.S. launch price of $59.99, with U.S. availability beginning January 9, 2025. Treat that as a price reference rather than a guarantee of the current retailer price.
Free tools Windows power users keep installed
One-click scans. No signup required.
The Samsung Galaxy Fit3 is a bargain for Samsung users who want a lightweight companion band for steps, sleep, notifications, and basic workouts. Its 1.6-inch display is relatively spacious for a band, and its close integration with Samsung phones makes it a logical low-cost choice within that ecosystem.
The Fit3 includes an optical heart-rate sensor, sleep monitoring, blood-oxygen measurement, stress measurement, automatic workout detection, and phone-notification features. Samsung lists up to 13 days of battery life and IP68 protection.
The compatibility warning matters
Samsung states that the Galaxy Fit3 is compatible only with Android phones. It is therefore not a suitable recommendation for iPhone owners, regardless of its low price. Buyers should also confirm the current phone and app requirements before purchasing, especially if they are using a non-Samsung Android phone.
The official specifications do not list onboard GPS, and independent buying guidance likewise identifies GPS as unavailable. For GPS-style route tracking, the Fit3 needs a connected phone rather than recording the route independently.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
The Fit3 also cannot perform body-composition measurement or ECG. Those omissions are not necessarily a problem for a basic activity band, but they matter if you are comparing it with more expensive Samsung wearables.
Choose it if: you use a Samsung Galaxy phone and want an inexpensive band for everyday activity, sleep, and notifications. Skip it if: you use an iPhone or need phone-free GPS.

4. Amazfit Active 2 — Best training features under $100
Checked price: $99.99 for the standard Amazfit Active 2 Round. The premium version costs more and does not fit the strict pre-tax $100 limit.
The Amazfit Active 2 is the feature-maximizer in this group. At the budget ceiling, it offers a watch-style interface and a more structured training toolkit than a basic activity band normally provides.
The standard model has a 1.32-inch AMOLED display, built-in GPS with map navigation, more than 160 workout modes, strength-training recognition, heart-rate and sleep tracking, recovery and readiness features, Bluetooth calls, and 5 ATM water resistance. Amazfit claims up to 10 days of typical-use battery life. It supports Android 7.0 and later and iOS 14 and later.
Why training-focused buyers should consider it
- GPS and maps: It can record routes independently and provide map navigation.
- Structured exercise tools: Strength-training recognition and a large collection of workout modes go beyond basic step counting.
- Recovery and readiness: These features can help users organize training and rest, although they should be treated as wellness guidance rather than medical analysis.
- Smartwatch functions: Bluetooth calling and a larger interface make it more versatile than a narrow tracker band.
- Cross-platform support: It works with recent Android and iOS devices.
The budget caveat
At $99.99, the standard Active 2 has essentially no room for a price increase, shipping charge that is included in the device total, or a model mix-up. Confirm that you are buying the standard Round version and that the pre-tax device price remains at or below $100. Do not assume the premium version qualifies.
Its watch-style design is also less discreet than the Inspire 3. And while the Active 2 reports health and training metrics, those readings are consumer wellness estimates—not diagnoses or substitutes for clinical equipment.
Choose it if: you want GPS, maps, workout depth, recovery information, and smartwatch functions in one device. Skip it if: you want the smallest possible band or do not want to monitor a price right at the budget limit.
5. CMF Watch Pro 2 — Best smartwatch-style design when available
Checked price: $69 official U.S. list price. The official U.S. product page was marked sold out when checked, so this is a conditional recommendation rather than the safest immediate purchase.
The CMF Watch Pro 2 is compelling on paper for buyers who dislike narrow fitness bands. It has a conventional smartwatch appearance, interchangeable bezels, multi-system GPS, and an 11-day battery claim at a historically low list price.
Its larger interface is better suited to watch-style notifications and workout glances than the Fitbit Inspire 3’s small screen. Multi-system GPS provides built-in route tracking, making it a potentially attractive alternative to the phone-dependent Fitbit and Galaxy Fit3.

Why availability and water use change the recommendation
Because the official U.S. page currently says “Sold out,” confirm stock, seller authorization, warranty coverage, and the return policy before choosing it. A low list price is not useful if the only available seller has unclear support or an inflated price.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsThe page also warns that the CMF Watch Pro 2 should not be used for swimming or prolonged submersion despite its IP68 rating. That makes it a weaker choice for regular swim use than the 5 ATM-rated Fitbit Inspire 3, Amazfit Bip 6, and Amazfit Active 2. Do not interpret an IP68 rating by itself as permission for swimming.
Choose it if: you want a watch-like design and built-in GPS and can verify current stock. Skip it if: you need a currently dependable purchase, regular swim use, or the clearest after-sales path.
Which fitness tracker under $100 should you buy?
- Choose the Fitbit Inspire 3 for the best balance of comfort, sleep tracking, core wellness features, phone compatibility, and simplicity.
- Choose the Amazfit Bip 6 for built-in GPS, a large display, offline maps, and the longest battery claim.
- Choose the Samsung Galaxy Fit3 if you use an Android phone—particularly a Samsung Galaxy phone—and want the least expensive ecosystem-friendly band.
- Choose the Amazfit Active 2 if structured training, maps, recovery features, strength recognition, and Bluetooth calls matter more than having a discreet band.
- Consider the CMF Watch Pro 2 only after confirming that it is back in stock at a trustworthy price and seller.
What to check before buying
- Confirm phone compatibility. Fitbit, Amazfit Bip 6, and Amazfit Active 2 support both major mobile platforms within their stated requirements. The Galaxy Fit3 is Android-only.
- Decide whether you need onboard GPS. If you want to run or cycle without carrying a phone, focus on the Bip 6 or Active 2. The Inspire 3 and Galaxy Fit3 depend on a connected phone for GPS-style route tracking.
- Check the exact model and current price. The Active 2 premium version is not part of this under-$100 ranking, and the Fitbit price is a promotional snapshot. The Samsung price is a launch-price reference, not a promise of current retail pricing.
- Match water protection to your use. The Inspire 3, Bip 6, and Active 2 carry 5 ATM ratings. The CMF Watch Pro 2’s official guidance specifically says not to swim or submerge it for prolonged periods.
- Think about the display format. A slim band is less intrusive for sleep and daily wear. A larger watch-style display is easier to read during workouts and when checking notifications.
- Separate core tracking from optional insights. Some Fitbit and Google Health features may require a premium service. Also, heart-rate, blood-oxygen, stress, sleep, calorie, readiness, and similar readings are wellness estimates, not medical diagnoses.
Care and replacement options
A tracker is worn every day, so the band and charging setup can matter almost as much as the device. Inspire 3 owners can look for compatible Fitbit Inspire 3 bands or a Fitbit Inspire 3 clip when they want a different wearing option. For any model, verify that replacement bands, chargers, and protective accessories match the exact model rather than assuming accessories are interchangeable across a brand’s lineup.
Health and accuracy note
These are consumer wellness devices. Heart-rate, blood-oxygen, stress, sleep, calorie, readiness, and related measurements can vary with fit, movement, skin contact, settings, and software. Use the data to observe trends and guide general activity; do not use it to diagnose a condition, change medication, or replace professional medical advice. Seek appropriate clinical care for health concerns.
Frequently Asked Questions
Which fitness tracker under $100 has built-in GPS?
The Amazfit Bip 6 and Amazfit Active 2 have built-in GPS and can record outdoor routes without relying on a phone for the GPS signal. The CMF Watch Pro 2 also has multi-system GPS, but its official U.S. page was sold out when checked. The Fitbit Inspire 3 and Samsung Galaxy Fit3 do not have onboard GPS.
What is the best fitness tracker under $100 for an iPhone?
The Fitbit Inspire 3, Amazfit Bip 6, and standard Amazfit Active 2 support iOS within their stated requirements. The Samsung Galaxy Fit3 is Android-only, so it is not suitable for iPhone owners.
Can these fitness trackers replace medical equipment?
No. Their heart-rate, blood-oxygen, sleep, stress, calorie, readiness, and related readings are consumer wellness estimates. Fit, movement, skin contact, settings, and software can affect results, and the readings should not be used as medical diagnoses.
Which under-$100 tracker is best for swimming?
The Fitbit Inspire 3, Amazfit Bip 6, and Amazfit Active 2 have 5 ATM water-resistance ratings. The CMF Watch Pro 2 is a poor choice for swimming because its official product guidance warns against swimming or prolonged submersion despite its IP68 rating. Always follow the manufacturer’s water-use instructions.
Recommended Free Tools
The Bottom Line
Bottom line: Buy the Fitbit Inspire 3 for the easiest everyday wellness recommendation. Choose the Amazfit Bip 6 when phone-free GPS is the priority, the Galaxy Fit3 when you are committed to Samsung’s Android ecosystem, and the Amazfit Active 2 when you want the deepest training feature set at the $100 ceiling. The CMF Watch Pro 2 is worth considering only if verified stock returns at a sensible price.
