We tested and compared six fitness trackers you can buy in Australia, from a budget Xiaomi band under 40 dollars to a premium Garmin watch. Every pick honestly weighs the hidden cost that catches most people out, the ongoing subscription.
The best fitness tracker is the one you will actually wear
The best fitness tracker is the one you will actually wear every day, and the biggest hidden question most buyers miss is whether the thing charges an ongoing subscription. Get that wrong and a cheap-looking tracker can quietly cost you more than a premium one over a few years.
The other real decisions are simpler. Do you need built-in GPS so you can map a run without your phone, and do you want a light, cheap band or a full GPS watch with a big screen, payments and an ECG feature? The six picks below span 40 dollars to 351 dollars, and we are upfront throughout that these gadgets track trends, not medical-grade numbers. They are consumer wellness tools for steps, runs, sleep and workouts, not health instruments.
The subscription trap - what actually costs you every month
This is the single most important thing to understand before you buy. Some trackers look cheap on the shelf but charge ongoing fees that add up fast. Fitbit hands you the best insights, things like Daily Readiness, deeper sleep analysis and richer health analytics, only with paid Fitbit Premium after a six-month free trial. Whoop has no upfront device cost at all but is subscription-only, meaning you pay every month forever or the band stops working. The Oura ring needs a subscription too.
By contrast, Garmin, Amazfit and Xiaomi charge nothing ongoing. The whole companion app is free, for the life of the device. Over five years a monthly subscription can easily cost more than the tracker itself, so always check the ongoing cost, not just the sticker price.
If you want the Fitbit ecosystem with Google Maps and Wallet on your wrist, the Charge 6 is excellent value at the sticker price, just go in knowing the best features sit behind Premium once your trial ends. If a subscription is a dealbreaker, the Garmin, Amazfit and Xiaomi picks here give you everything for the purchase price alone.
How accurate are fitness trackers really?
Honesty matters here more than anywhere else, so let us be plain. Wrist-based heart rate is a convenient estimate. It is good at rest and during steady efforts like a jog or a walk, but it gets less reliable during HIIT, weights sessions or in cold weather, when the sensor struggles to read blood flow at the wrist. If you want genuinely accurate heart rate for hard training, a chest strap beats any wrist tracker.
Step counts and calorie burn are approximations too, useful for spotting patterns rather than counting to the exact figure. Sleep staging, the light, deep and REM breakdown, is a rough trend, not a sleep-lab reading. SpO2 and ECG features are there for general wellness and awareness only. They are not medical devices and they are not a substitute for seeing a doctor. The sensible way to use any of these numbers is to watch trends over weeks, not to diagnose anything from a single reading.
Band or full GPS watch - which do you need?
A 40 to 60 dollar band nails the core job. Steps, heart rate, sleep tracking and phone notifications, all in a light package that lasts one to three weeks on a charge and disappears on your wrist. For a lot of people that is genuinely all they need, and the Xiaomi bands below do it superbly.
You pay more for a watch, and what you are buying is a bigger AMOLED screen, built-in GPS, offline maps, on-board music, contactless payments and in some cases an ECG. The honest question to ask yourself is which of those features you will actually use. If you never leave the house without your phone and you do not run, a band may serve you better than a watch you paid triple for.
Built-in GPS vs connected GPS - the runner question
This is the distinction that trips up runners. Built-in GPS means the tracker has its own satellite chip and records your run distance and route without your phone anywhere near you. The Amazfit Bip 6 and Active 3, the Fitbit Charge 6 and the Garmin all have built-in GPS.
Connected GPS, which is what most cheap bands use including the Xiaomi base bands, borrows your phone GPS instead. It works fine, but it means you have to carry your phone on every run to get an accurate map and pace. If you run regularly and want to leave your phone at home, prioritise built-in GPS. If you always run with your phone or do not map runs at all, connected GPS is perfectly fine and saves you money.
Battery life - the AMOLED trade-off
Battery is where the marketing numbers and real life diverge. The Xiaomi bands and the Amazfit and Garmin watches last roughly one to three weeks per charge. The Fitbit Charge 6 is closer to a week. Those are best-case figures with the screen mostly off, raised only when you flick your wrist.
The catch is the always-on display. Turning on an always-on AMOLED screen, so the time is visible without a wrist flick, roughly halves any of those figures. An 11-day Garmin becomes five or six days, a two-week Amazfit becomes one. There is no free lunch here, so if you love an always-on screen, plan to charge more often, and treat every quoted battery figure as a best case.
What about the Apple Watch?
It is the obvious question, so here is the honest answer. The Apple Watch is an excellent smartwatch if you own an iPhone, but it is not really a fitness tracker. The battery lasts about a day, which makes it awkward for sleep tracking since you have to find time to charge it. It only works with iPhone, so Android users are out entirely. And on Amazon Australia it is often sold by third-party resellers above Apple list price.
If you want one, buy it directly from Apple or a major retailer rather than a marketplace reseller. But for pure fitness tracking with multi-day battery that survives a night of sleep tracking, the picks in this guide do the job better, and for a lot less money.
A note on no-name trackers and star ratings
The cheap end of the market is flooded with generic smart watch for men women style listings that boast inflated, pooled review counts and fantasy specifications you should not believe. A no-name watch claiming a week of GPS battery and medical-grade everything for 25 dollars is telling you a story, not a spec sheet.
Stick to recognised brands, Xiaomi, Amazfit, Fitbit and Garmin, and read the recent Australian reviews rather than the headline star average. Even some legitimate watches pool their rating across every colour variant, which is why the Garmin listing here mixes reviews from several models. A high star count is reassuring only when you can see the reviews are recent and about the product you are buying.
Frequently Asked Questions
Do fitness trackers need a monthly subscription?
Some do and some do not, and it is the most important thing to check before buying. Fitbit unlocks its best insights only with paid Fitbit Premium after a six-month trial, Whoop is subscription-only with no real device cost, and the Oura ring needs a subscription too. Garmin, Amazfit and Xiaomi charge nothing ongoing, so the full app is free for the life of the device.
How accurate are fitness trackers?
They are best treated as estimates that show trends, not precise medical readings. Wrist heart rate is good at rest and steady efforts but less reliable during hard intervals, weights or cold weather, where a chest strap is more accurate. Step counts, calorie burn and sleep stages are all approximations, so use them to spot patterns over weeks rather than to draw conclusions from any single number.
Whats the difference between a fitness band and a smartwatch?
A band focuses on the core tracking job, steps, heart rate, sleep and notifications, in a light, long-battery, low-cost package. A smartwatch adds a bigger AMOLED screen, built-in GPS, offline maps, on-board music, contactless payments and sometimes an ECG feature, for a higher price. If you will not use those extras, a band often serves you better.
Do I need built-in GPS?
You need built-in GPS if you want to map your runs or rides without carrying your phone, because the tracker records the route on its own satellite chip. If you always run with your phone, or you do not map runs at all, connected GPS that borrows your phone signal is perfectly fine and lets you spend less on the device.
Fitbit vs Garmin - which is better?
It depends on what you value. Fitbit has the more polished everyday app, Google Maps and Wallet on the wrist, and an ECG feature, but its best insights sit behind a paid Premium subscription after the trial. Garmin has a deeper training and recovery app in Garmin Connect that is completely free with no subscription, plus better battery, but no ECG on the vivoactive 5. Runners and serious trainers tend to prefer Garmin, casual users who want Google apps lean Fitbit.
Are the SpO2 and ECG features medical-grade?
No. The SpO2 and ECG features on these trackers are wellness and general-awareness tools, not medical devices, and they are not a substitute for professional care. They can be a handy nudge to pay attention to your wellbeing, but if you have any health concern you should see a doctor rather than rely on a wrist reading.
How long do fitness tracker batteries really last?
In normal use, bands and the Amazfit and Garmin watches last roughly one to three weeks per charge, while the Fitbit Charge 6 is closer to a week. Those are best-case figures with the screen mostly off. Switching on an always-on AMOLED display roughly halves the battery life, so plan to charge more often if you keep the screen lit.
