The 1.58″ AMOLED touchscreen is gorgeous and easy to read in sunlight. You get on-wrist Bluetooth calling with a built-in speaker and mic, Amazon Alexa for hands-free voice commands, Google Wallet for tap-to-pay, Google Maps directions, and YouTube Music controls. Fitness tracking is strong: built-in GPS, 40+ exercise modes, Active Zone Minutes, Daily Readiness Score, and a Cardio Fitness Score. What the Versa 4 does NOT have: ECG (only the Charge 6 and Sense 2 have that), no EDA stress sensor, and no gym equipment heart rate streaming. The battery runs up to 6 days — shorter than the Charge 6 (7) or Inspire 3 (10), but fast charge means 12 minutes gets you a full day. At $229.95, you're paying $70 more than the Charge 6 primarily for the bigger screen, on-wrist calling, and Alexa. The honest take: if you want a Fitbit that looks and feels like a real smartwatch on your wrist and you value the big screen and phone calls, the Versa 4 delivers that. If fitness tracking accuracy and health sensors are the priority, the Charge 6 gives you more for less. Why you'd choose this smartwatch 1.58″ AMOLED — Biggest Fitbit DisplayLarge, vibrant 336 × 336 px color touchscreen with always-on display option.

Fitbit Versa 4 — Frequently Asked Questions Is the Versa 4 better than the Charge 6?It depends on what you value. The Versa 4 ($229.95) is a full smartwatch with a large 1.58″ display, on-wrist phone calling, Amazon Alexa, and a watch-style form factor. The Charge 6 ($159.95) is a slim fitness band with ECG (Versa 4 lacks this), more accurate ML-enhanced heart rate, gym equipment HR streaming, a longer 7-day battery (vs 6), and costs $70 less. Both share GPS, NFC, Google Maps, Google Wallet, YouTube Music, and 40+ exercise modes. For pure fitness tracking, the Charge 6 wins. For a smartwatch with calls and a big screen, choose the Versa 4. Is the Versa 4 better than the Inspire 3?Yes, significantly. The Versa 4 adds built-in GPS, a much larger 1.58″ display, on-wrist calling, Alexa, NFC payments, Google apps, 40+ exercise modes (vs 20+), and a physical side button. The Inspire 3 ($99.95) counters with a much lower price, longer battery (10 days vs 6), lighter weight, and a slimmer form factor. Is the Versa 4 better than the Sense 2?The Sense 2 ($299.95) adds ECG, continuous EDA stress tracking (cEDA), skin temperature tracking, and a gyroscope — all of which the Versa 4 lacks. Both share the same 1.58″ display, on-wrist calling, Alexa, GPS, NFC, Google apps, and 40+ exercise modes. If advanced health monitoring matters, the Sense 2 justifies the $70 premium. If you don't need those extra sensors, the Versa 4 saves you $70. Does the Versa 4 have an ECG sensor?No. The Versa 4 does not have an ECG sensor. In the current Fitbit lineup, only the Charge 6 and Sense 2 offer ECG for atrial fibrillation detection. The Versa 4 does have irregular heart rhythm notifications via the optical sensor, but that is not the same as an on-demand ECG reading. Can you take phone calls on the Versa 4?Yes. The Versa 4 has a built-in speaker and microphone, allowing you to answer and make Bluetooth calls directly from your wrist when your phone is nearby. This is a feature the Charge 6 and Inspire 3 do not have. The Sense 2 also supports on-wrist calling. Does the Versa 4 have Google Wallet and Google Maps?Yes. The Versa 4 supports Google Wallet via NFC for contactless payments and Google Maps for turn-by-turn directions on your wrist. It also supports YouTube Music playback controls. These features are shared with the Charge 6 and Sense 2 but are absent from the Inspire 3. How long does the Versa 4 battery last?Up to 6 days on a single charge with typical use. Fast charge gives you a full day's use in just 12 minutes. Heavy GPS use and always-on display will reduce battery life. For comparison: Inspire 3 lasts 10 days, Charge 6 lasts 7 days, Sense 2 also lasts 6 days with fast charge. Does the Versa 4 require Fitbit Premium?The Versa 4 works without Premium for core features — heart rate, GPS, exercise tracking, sleep stages, notifications, Google apps, calling, and Alexa. Premium ($9.99/month or $79.99/year) unlocks Daily Readiness Score, Sleep Profile, advanced analytics, guided workouts, and wellness reports. Includes 6 months free for new and returning users.
