A hundred dollars used to buy a pedometer with a heart-rate sensor bolted on. In 2026 it buys a device with sleep staging, HRV, blood oxygen, skin temperature and, from Google, FDA-cleared AFib alerts. The budget end of the market has quietly become the interesting end, because the three features Whoop and Oura charge a subscription for are now free on a $99 band. This guide sorts the sub-$100 trackers into three honest price tiers, explains exactly what disappears as the price falls, and names the one case where you should spend $160 instead.

Three answers for three budgets. At $50, the Xiaomi Smart Band 10: the best screen and battery you can buy for the money. At $99, the Fitbit Air: the deepest health tracking under $100 with AFib alerts and a free readiness score, no screen. Also at $99, the Amazfit Helio Strap if what you want is Whoop's recovery idea without Whoop's rent. Nothing under $100 has built-in GPS; if you need it, the Fitbit Charge 6 at $159.95 is the real floor.
What you lose as the price drops
Understand this before the picks, because the gaps are not where the marketing suggests. Every tracker in this guide counts steps, reads heart rate, tracks sleep, measures SpO2 and survives a swim. The differences are in five places.
- Built-in GPS: nobody has it. Every band under $100, Fitbit included, maps outdoor runs from your phone. If you run without a phone, you are shopping above $100. See fitness bands with built-in GPS.
- Validated sleep science: only Fitbit. Xiaomi, Amazfit, Samsung and Huawei all show sleep stages. Only Fitbit's staging has a decade of published validation behind it.
- Heart-rhythm alerts: only Fitbit. The Air and Inspire 3 carry Fitbit's AFib notification. Nothing from the Chinese brands does.
- A readiness score you should act on: Fitbit and Amazfit. Xiaomi's vitality-style score and Huawei's equivalents exist, but Fitbit's Daily Readiness and Zepp's recovery score are the two with enough rigour to change your training.
- Data portability. Fitbit writes to Google Health, not Apple Health. Xiaomi's Apple Health sync is partial. Amazfit's Zepp app syncs both platforms cleanly.
Tier one: around $50
Xiaomi Smart Band 10, $45 to $55
The default budget band for a reason. A 1.72-inch AMOLED that is genuinely readable outdoors, 5 ATM water resistance, 150-plus sport modes, sleep staging, SpO2 and a claimed 21-day battery that lands closer to two weeks with sensible settings, which is still double any Fitbit. It works with iPhone and Android through Mi Fitness and has no subscription anywhere in it. Heart rate is reliable at steady effort and loose during intervals; sleep interpretation is thin; Apple Health sync is a detour. For $50 none of that matters much. Our full test is the Smart Band 10 review.
Amazfit Band 7, $49.99
Xiaomi's closest rival, from a company that is technically Xiaomi's ecosystem partner. The Band 7 has a slightly smaller screen, a similar two-week battery, Alexa built in, and the Zepp app, which syncs to Apple Health and Health Connect far more cleanly than Mi Fitness. If data portability matters more to you than screen size, pick this over the Xiaomi.
The ones to avoid at this price
Marketplace listings are full of unbranded "smart watches" at $25 to $40 with spec sheets that promise blood pressure, blood glucose and ECG. None of them can do any of those things; the readings are generated numbers. If a $30 device claims to measure blood pressure without a cuff, it is not a bargain, it is a toy. Stick to the two brands above.
Tier two: $60 to $80
Samsung Galaxy Fit3, about $60
A 1.6-inch screen, a 13-day battery and, unusually at this price, fall detection with emergency SOS. It is the right band for an Android household and especially a Galaxy one, where Samsung Health ties it to everything else. It does not pair with iPhone at all, and the sleep coaching is Samsung's lighter version. For an older relative on Android who wants a readable screen and a safety net, it beats both $50 bands; our trackers for seniors guide goes deeper.
Huawei Band 10, about $60
A metal-cased band with a two-week battery and Huawei's TruSleep staging, which is better than Xiaomi's. The Huawei Health app works on iPhone and Android but sits outside Google Play in some regions, and Health Connect sync is limited. It does not measure blood pressure, whatever the listing implies; that is the Watch D3, at six times the price. A good band for people already in Huawei's ecosystem and a slightly awkward one for everyone else.
Tier three: the $99 line
Fitbit Air, $99: the best health tracker under $100
Google's screenless pebble is the reason this price point got interesting. For $99 you get 24/7 heart rate, HRV, SpO2, skin temperature, validated sleep staging, a 0 to 100 sleep score, AFib alerts and a Daily Readiness Score, all free in the Google Health app, in a 12-gram band that runs a week and swims to 5 ATM. Whoop charges $199 a year for the equivalent readiness number. There is no screen and no GPS, by design. It works with iPhone and Android, but its data lives in Google Health rather than Apple Health, which iPhone owners should read about in best fitness tracker for iPhone. Full verdict in the Fitbit Air review.
Fitbit Inspire 3, $99.95: the Air with a screen and without AFib depth
Launched in 2022 and usually the cheapest Fitbit on the shelf because it is discounted so often, the Inspire 3 gives you a small colour screen, up to 10 days of battery, steps, sleep stages, HRV and SpO2 in the same Google Health app. It lacks the Air's skin temperature sensor and newer hardware, and the display is narrow. If you want a Fitbit and a screen under $100, this is the only option, and at its frequent $80 sale price it is a very good one. The whole Fitbit lineup by price is in cheapest Fitbit.
Amazfit Helio Strap, $99.99: Whoop's idea, paid once
A screenless recovery band running Zepp's readiness, sleep, HRV and training-load stack with nothing paywalled, about 10 days of battery, and the option to wear it on the upper arm for far better exercise heart rate than any wrist device. It is the one tracker under $100 aimed at people who train rather than people who want health monitoring, and it is the natural pick for the gym; see best fitness tracker for weight lifting. No AFib alerts, a less polished app than Google's. Reviewed in Amazfit Helio Strap review.

When to spend $160 instead
One situation. If you run or ride outdoors and do not want to carry a phone, nothing under $100 will map the route, and buying a $50 band then a $160 one six months later costs more than buying the right thing once. The Fitbit Charge 6 at $159.95, routinely around $120, is the cheapest band from a trustworthy brand with built-in GPS, and it adds an ECG app and contactless payments. Its likely successor, the Fitbit Edge, is revealed on 12 October at a leaked price near $180, which means the Charge 6 is about to get cheaper. Wait a week if GPS is your reason to stretch.
Everyone else should resist. The jump from $99 to $200 buys Garmin's training metrics or Polar's heart-rate pedigree, which matter if you train to a plan and not otherwise; best fitness trackers without a subscription ranks that tier.
Or spend nothing
If the only number you care about is steps, your phone already counts them, and a good pedometer app presents the figure better than most bands do; best pedometer apps and best step counter apps for Android cover the options. A tracker earns its place for the things a phone cannot do: heart rate, sleep, and workouts where the phone stays in the locker. Be honest about whether that is you before spending even $50.
Whatever you buy, it writes to Apple Health, Google Health or Health Connect, and Fitcoin reads all three. Our app builds a daily FitScore from your steps and detected workouts, pays it back in partner rewards, and adds Sleep, Recovery and Energy coaching, so a $50 Xiaomi earns exactly what a $400 ring does for the same day. That is the point of a budget tracker: the sensor is cheap, and the scoring does not have to be.
Frequently asked questions
What is the best fitness tracker under $100?
The Fitbit Air at $99 if you want the deepest health tracking and do not need a screen; the Xiaomi Smart Band 10 at about $50 if you want a bright screen and two weeks of battery; the Amazfit Helio Strap at $99.99 if you want Whoop-style recovery scoring with no subscription.
Is a $50 fitness tracker worth it?
Yes, if it is a Xiaomi Smart Band 10 or Amazfit Band 7. Both have real AMOLED screens, 5 ATM water resistance, heart rate, SpO2, sleep staging and a free app. What you lose against a $99 device is built-in GPS, validated sleep science, AFib alerts and a readiness score worth trusting.
Does any fitness tracker under $100 have built-in GPS?
Not from a brand worth buying. Every band under $100, including the Fitbit Air and Inspire 3, uses your phone's GPS. Built-in GPS starts at the Fitbit Charge 6 at $159.95, often discounted to around $120.
Do cheap fitness trackers need a subscription?
No. Xiaomi, Amazfit, Samsung and Huawei have no subscription at all. Fitbit's Google Health Premium at $9.99 a month is optional and does not gate sleep score, readiness or HRV on the Air or Inspire 3.
Should I buy a cheap fitness tracker or just use my phone?
If you only want a step count, your phone already does it for free. A tracker earns its keep for heart rate, sleep and workouts where you do not carry a phone. If that is not you, a good pedometer app and the money saved is the honest answer.
