The Xiaomi Smart Band 10 is the strongest value-first choice in this under-$100 shortlist, but it has no built-in GPS. For phone-free GPS, consider the Amazfit Active 2 if its exact version is still under $100; the Fitbit Inspire 3 is a beginner-friendly alternative for wellness and sleep tracking. Prices and availability change, so confirm the exact model, seller, and current price before buying.

1. Xiaomi Smart Band 10 — Best value-first pick
TechRadar names the Xiaomi Smart Band 10 its best cheap fitness tracker overall. Android Authority describes a 1.72-inch AMOLED screen and more than 150 workout modes, while noting that it lacks built-in GPS. Tom’s Guide reported the standard edition at $51 on Amazon U.S. when its review was accessed; that price is a snapshot and should be checked again.
The GPS limitation matters: route tracking depends on a paired phone. Do not confuse the standard edition with the Ceramic Edition, which Tom’s Guide listed at a different price. Android Authority also notes that heart-rate accuracy can vary with fit, so treat readings as wellness information rather than medical measurements.
Choose it if: value and a broad activity feature set matter more than phone-free GPS. Look elsewhere if: you want to leave your phone behind for route recording.
2. Fitbit Inspire 3 — Best for approachable wellness and sleep
TechRadar lists the Inspire 3 with activity and heart-rate tracking, Android and iOS support, no built-in GPS, and a 10-day battery claim. It can use a phone connection for route tracking. iTechGuides describes it as a beginner-friendly sleep-tracking option.
Fitbit’s core tracking is distinct from optional Premium insights, according to TechRadar. iTechGuides also notes that some advanced insights require Premium. Check the current terms for the specific feature you want, as service names and plans can change.

3. Samsung Galaxy Fit3 — Best for Samsung phone integration
iTechGuides includes the Galaxy Fit3 in its under-$100 comparison and reports that it does not work with iPhone. Its guide describes connected GPS, meaning the phone is needed for route tracking rather than the band recording a route independently.
Confirm current Samsung compatibility documentation and U.S. availability before buying, especially if you use a non-Samsung Android phone. Compatibility can depend on the exact phone, app, and region.
Choose it if: you use a compatible Android phone and want a band within Samsung’s ecosystem. Look elsewhere if: you use an iPhone or need phone-free GPS.
4. Amazfit Active 2 — Best watch-style option with built-in GPS
TechRadar notes that the Active 2 is a fitness watch rather than a slim band, but includes it among trackers under $100. Its August 18, 2026 deals coverage reported an Amazon price of $99.99 and 164 sports modes; its broader guide describes built-in GPS. Confirm the exact variant and live U.S. price before treating it as an under-$100 buy.

The vívosmart 5 belongs on this list only when a reliable authorized seller offers the exact model below $100.

What to check before buying
- Verify the exact model and current price. Recheck the seller, edition, shipping, warranty, and return terms. A price reported in a guide is only a snapshot.
- Decide whether you need built-in GPS. The Xiaomi Smart Band 10, Fitbit Inspire 3, and Garmin vívosmart 5 lack it, according to TechRadar. TechRadar describes built-in GPS on the Amazfit Active 2; iTechGuides reports connected GPS for the Galaxy Fit3.
- Check phone and app compatibility. The cited guides report Android and iOS support for Xiaomi Smart Band 10, Fitbit Inspire 3, and Garmin vívosmart 5; iTechGuides says Galaxy Fit3 does not work with iPhone. Confirm requirements for your phone, model, and region.
- Consider subscriptions and app features. Fitbit Premium offers additional insights, while core tracking is separate. Verify current plan terms and whether the specific insights you want are included.
- Interpret wellness data cautiously. Activity, heart-rate, sleep, recovery, and similar readings are not proof of medical accuracy. Fit and use can affect results.
