Fitbit Inspire 3

Battery life and display

Fitbit claims up to 10 days, but that figure requires disabling always-on display. PCMag measured 8 days with normal use and about 3 days with always-on enabled. Tom’s Guide finished a week at 10% battery with always-on and daily workouts. CNET confirmed the 10-day figure with 24/7 wear. The 0.5-inch AMOLED screen is bright and readable in daylight, but the text is tiny and cannot be resized. Three brightness levels and four display timeout options are available. The touchscreen can be unresponsive with sweaty hands.

Heart rate and workout tracking

The Inspire 3 tracks heart rate 24/7 with an optical sensor. Tom’s Guide found consistency with an Apple Watch Series 7 during a Peloton ride (both averaged 142 bpm). PCMag found significant underestimation during outdoor runs: the Inspire 3 averaged 137 and 134 bpm on two runs versus 176 and 174 bpm on an Apple Watch Series 8, and 134 bpm versus 159 bpm on a chest strap. The discrepancy may be activity-type-dependent or unit-to-unit variance. Without connected phone GPS, distance estimates can be significantly off — PCMag measured 1.25 mi estimated versus 1.0 mi actual on a run.

Premium subscription and running costs

Many of the most useful features — sleep score, Daily Readiness Score, 90-day health trends, Sleep Profile — require Fitbit Premium at $9.99/month or $79.99/year after the included 6-month trial. CNET notes Premium is “fast becoming an essential part” of the Fitbit experience. The device itself has no recurring cost beyond the subscription. Accessory bands cost $19.95 (clip), $34.95 (translucent silicone), or $69.95 (stainless steel mesh). The clip disables heart rate and sleep score measurements. An extended warranty adds a second year with accidental-damage coverage for $19.99.

Is it worth it?

At $75–90 on sale, the Inspire 3 is a strong value: color AMOLED, 8–10 day battery, comprehensive sleep and activity tracking, and the included Premium trial make it a compelling entry tracker. Missing GPS and the small screen are acceptable tradeoffs at that price. At $91–100 it is fair value — still the cheapest color-display Fitbit, but alternatives like the Xiaomi Mi Band 7 (~$60) offer larger screens with similar features. Above $120 it is not recommended at MSRP; the Fitbit Luxe ($129.95) offers a more premium design, or the Charge 5/6 ($131–159.95) adds GPS and more sensors. The Google Store lists the Inspire 3 at $99.95. Tom’s Guide noted it often on sale around $75 at various retailers in August 2024, and PCMag listed it at $79 at Best Buy and $94 at Walmart in March 2023.
