Pacer, Google Fit, Samsung Health and WeWard compared — accurate phone-only counting, Heart Points and free health suites without a watch.
You do not need a fitness band to learn how little you walk: the phone already in a pocket runs a dedicated low-power motion chip and counts steps with surprising accuracy, as long as the app stays installed and the phone stays on you. The interesting differences are what surrounds the count — social challenges, a broader health suite, a neutral hub for data from every device, or even cash rewards. The three apps reviewed in depth below were picked as the free options people actually live with in 2026, and the questions cover accuracy, the 10,000-step myth and battery cost.
Pacer is the best-rated phone-only pedometer: automatic counting with minimal battery use, plus groups and challenges so walking stays social.
It counts automatically without GPS or a wristband, using the phone's motion sensors with barely noticeable battery drain, and the design is deliberately simple — open it and the day's number is already there. Around the count it adds challenges, groups for walking with friends and structured walking-training programmes, so it occupies the middle ground between a bare pedometer and a heavyweight health platform. The free version carries ads, and the freemium split puts training plans and some metrics behind payment, but the core step counting that most people want needs nothing extra.
Google Fit is the free, ad-free hub that centralises activity from dozens of apps and watches, with WHO-developed Heart Points.
Its role is aggregation as much as tracking. Heart Points, developed with the WHO, reward brisk walking rather than just movement, and the app syncs with dozens of services and devices including Wear OS and Xiaomi wearables, so data from different gadgets lands in one history. There is no advertising and no subscription, which makes it the natural neutral hub. The trade-off is depth and momentum: individual metrics are less detailed than in specialist apps, the redesigns left it with a modest 3.5-star rating, and Google has been shifting features toward Fitbit.
Samsung Health is a complete free health suite — steps, workouts, sleep, food and medication reminders — especially rewarding with a Galaxy.
Beyond the pedometer it logs workouts, sleep and meals and includes a medication section that reminds you about each dose, all at no charge and usable even on non-Galaxy phones. Pair it with a Galaxy watch and the suite expands to blood pressure, ECG and body-composition measurements, the deepest integration in the group and one of the most complete free options available. The limitation is the ecosystem: it is only fully useful inside Samsung hardware, some metrics explicitly require a Galaxy watch, and the breadth of features makes the interface dense.

Questions & answers
How accurate is counting steps with just a phone?
More than people expect. Modern accelerometers recognise the walking gait with a margin small enough for everyday use, provided the phone is actually on you in a pocket or bag; left on a desk, those steps simply do not count, which is where a band helps. For knowing whether you move enough each day, the phone is sufficient.
How many steps should I aim for per day?
The famous 10,000-step target originated in a Japanese marketing campaign, not research. Current evidence puts the meaningful threshold around 7,000-8,000 steps a day, and even going from sedentary to 4,000 already improves health markers. Consistency beats the exact number: 7,000 daily is better than 15,000 every Saturday.
Do pedometer apps drain the battery?
Very little. These apps use the low-power step chip built into phones rather than waking the main processor, typically 1-3% a day, and Pacer and Leap's Step Counter are especially efficient. The real battery cost comes only from GPS features, such as recording a route on a map, and only while actively in use.
