Display: 1.43 inch AMOLED, 466 x 466
Battery: Up to 10 days typical use
GPS: Built-in, single band
Sensors: Optical HR, SpO2, accelerometer
Water rating: 5 ATM

Best for: casual fitness tracking and notifications, not serious training data

The short verdict

The PulseFit 3 is an honest budget tracker with one important caveat: treat its numbers as trends, not measurements. Steps, notifications and battery life are all solid, and the AMOLED screen is better than the price suggests. But heart rate drifts during interval work and GPS wanders in dense areas. Good for building a habit. Not good enough to train by.

Pros and cons at a glance

What we liked

Bright AMOLED screen that stays readable in direct sunlight
Genuine 8 to 10 day battery with always-on display switched off
5 ATM rating means it survives swimming, not just rain
Step counting and notification mirroring are reliable and low-fuss

Where it falls short

Heart rate lags badly during interval training and HIIT
Single-band GPS drifts between tall buildings
Sleep staging is directionally useful but not clinically meaningful
Companion app pushes upsell notifications by default

What a budget tracker can and cannot do

Every wrist-based fitness device estimates. It shines light into your skin, measures what comes back, and infers a heart rate. That inference is good when conditions are stable and poor when they are not.

The PulseFit 3 sits exactly where you would expect for the money. The hardware is competent, the algorithms are conservative, and the failure modes are the normal ones. What matters is knowing which numbers to trust.

Heart rate accuracy

Against a chest strap over steady walking and a consistent jog, readings tracked within a few beats. That is genuinely good at this price.

Interval work is a different story. During short high-intensity efforts the sensor lagged 15 to 25 seconds behind the strap and consistently under-reported peaks. If your training is zone-based, this watch will mislead you. Pair a chest strap over Bluetooth instead, which the watch supports.

GPS

Single-band GPS is the cost saving. On open roads and park loops the traced route is clean and distance lands within about two percent.

Between tall buildings the track visibly wanders, occasionally cutting corners through structures. Distance over a full run still ends up close, because errors cancel out, but individual splits become unreliable.

Display and daily use

The 1.43 inch AMOLED is the standout. It is bright, sharp and readable in harsh sunlight, which is where cheaper LCD trackers fail completely.

Notification mirroring is quick and legible. Watch faces are plentiful, though the good ones are buried behind an app store that pushes promotions.

Battery

With always-on display off and one GPS session a week, it lasted between eight and ten days across repeated cycles. Enabling always-on roughly halves that. Daily GPS running brings it to about five days.

Sleep and SpO2

Sleep duration is credible. Stage breakdown is an estimate and should be read as a weekly trend rather than a nightly verdict. Overnight SpO2 is a wellness indicator, not a medical measurement, and should never be used to make a health decision.

Verdict

A good habit-building device with an unusually nice screen. Not a training instrument. Anyone serious about structured training should add a chest strap or spend considerably more.
