The Samsung Galaxy Fit 3 is a lightweight fitness tracker designed for users who want daily activity monitoring, workout tracking, sleep insights and smart features without wearing a large smartwatch. It features a 1.6-inch AMOLED display, Samsung Health integration, over 100 workout modes, heart-rate monitoring and up to 13 days of battery life under Samsung’s test conditions.

The Fit 3 uses a dedicated quick-release strap system, so buyers should choose bands specifically compatible with Samsung Galaxy Fit3 / SM-R390 instead of assuming older Galaxy Fit straps will fit.
