Fitbit Blaze review: accurate heart tracking and 3.5-day battery charge, but thick bezel design is ugly and software is limited compared to other smartwatches
Joanna Stern / Wall Street Journal :
Context & Ripple Effects
The Blaze arrived as Fitbit's first real swing at the watch form factor: the January announcement promised a $200 device with five-day battery, improved heart-rate sensing, a touch LCD, and swappable bands shipping in March (the CES unveiling set those expectations). Joanna Stern's Wall Street Journal verdict lands on the promise half-kept — accurate heart tracking and roughly 3.5 days per charge, but a thick-bezel design she calls ugly and software that trails other smartwatches.
First-order effects
- Buyers shopping the $200 tier now face a clear trade-off: Blaze wins on battery and heart-rate accuracy but loses on looks and smartwatch features to competitors' watches.
Second-order effects
- The software gap pressures Fitbit to keep iterating on the platform rather than rest on tracker sales — a pressure visible again when the Ionic review flags buggy software and ugly design, and the Versa review notes poor notification support despite borrowing Apple Watch cues.
Third-order effects
- If the pattern holds, Fitbit is structurally caught between two product identities: the multi-day-battery fitness tracker its hardware excels at, and the app-driven smartwatch its software keeps failing to match — a tension each subsequent device (Alta HR, Ionic, Versa, eventually the cramped-screened Luxe) inherits.
The trend: Fitness-tracker makers moving upmarket into smartwatches keep hitting the same wall: hardware and battery life are achievable, but matching established smartwatch software platforms is not.
