Fitbit Inspire 3 vs Garmin Venu 3
The Verdict
Fitbit Inspire 3 delivers excellent value for casual fitness tracking at just $99, offering essential health monitoring including heart rate, SpO2, and sleep tracking on a compact 0.73-inch AMOLED display. Battery life reaches 10 days with its lightweight 20g design. Garmin Venu 3 ($449.99) represents a premium option with substantially more capability: larger 1.4-inch always-on display, built-in GPS for accurate workout mapping, NFC for contactless payments, and ECG functionality. Its 14-day battery in smartwatch mode and extended 26-hour GPS endurance appeal to serious athletes. Both offer 5ATM water resistance and comprehensive health tracking. Choose Inspire 3 if you need basic daily fitness monitoring without breaking the bank; select Venu 3 if you demand advanced sports features, standalone navigation, and are willing to invest significantly in a comprehensive fitness ecosystem.
