Fitbit Inspire 3 vs Fitbit Versa 4
The Verdict
Inspire 3 delivers exceptional value for fitness basics at $99, featuring a compact AMOLED display, solid health tracking (SpO2, skin temperature, heart rate), and impressive 10-day battery life,making it ideal for budget-conscious users prioritizing simplicity. Versa 4 justifies its $179 price with a significantly larger 1.58-inch display, always-on functionality, ECG capability, built-in GPS, NFC payments, and Wi-Fi connectivity, though battery drops to 6 days and the watch weighs nearly double.
