Key Differences
-
The Fitbit Sense 2 has 700% more rated battery life
Not a close call. The Fitbit Sense 2 lists 6 days and the Apple Watch SE 2 lists 18 h. That’s a substantial gap. Ratings assume typical use; GPS workouts and always-on screens will shorten both.
-
The Fitbit Sense 2 has an always-on display
Having an always-on display gives the Fitbit Sense 2 one more thing the Apple Watch SE 2 can’t match. With the Fitbit Sense 2, a glance is enough; with the Apple Watch SE 2, the screen has to wake up first.
-
The Fitbit Sense 2 has an ECG app
Not every buyer will care, but the Fitbit Sense 2 gives you an ECG app and the Apple Watch SE 2 doesn’t. An ECG app can record a single-lead reading that you can share with your doctor, where regional approval allows it.
-
The Apple Watch SE 2 has a cellular option
The Fitbit Sense 2 doesn’t offer this at all, so if you need a cellular option, the choice is made for you. Cellular models usually cost more and need a plan, so it’s only worth it if you’ll use the freedom.
-
The Fitbit Sense 2 has blood-oxygen readings
It’s a simple yes-or-no difference: the Fitbit Sense 2 includes it, the Apple Watch SE 2 does without. The Fitbit Sense 2 can take blood-oxygen readings; the Apple Watch SE 2 can’t.
