Quick Take

The Fitbit Inspire 3 is the newer model: it upgrades to a color AMOLED touchscreen and adds extra wellness sensors like SpO₂ and skin temperature variation. The Inspire 2 is an older tracker with the same “core basics” (steps, workouts, sleep), and it can be a good value if you find it cheaply—especially since it’s less commonly sold new now.

Key Differences

• Display: Inspire 3 has a color AMOLED display and supports Always-On mode; Inspire 2 uses a grayscale PMOLED display.
• Sensors / wellness metrics: Inspire 3 adds SpO₂ and a device temperature sensor used for skin temperature variation tracking; Inspire 2 doesn’t offer those metrics in the same way. SpO₂ is a wellness metric for noticing trends, not for diagnosing conditions.
• Form factor: Inspire 3 is slightly longer/wider (and a bit thinner) than Inspire 2.

Who Should Choose Fitbit Inspire 3

• You want a color display with better readability in varying light conditions
• You need SpO2 monitoring for breathing awareness or sleep apnea concerns
• You prefer the always-on display option
• You want skin temperature tracking for wellness monitoring
• You’re buying new and want the current model with ongoing support

Who Should Choose Fitbit Inspire 2

• You can find one at a significant discount (it’s been discontinued)
• You don’t need SpO2 or skin temperature features
• The monochrome screen is acceptable for your use case
• You value the longer 12-month Premium trial (if purchasing new old stock)
• You want a slightly smaller device
