Does the Fitbit Sense need a subscription?

The watch works without one, but detailed insights, guided programs and daily readiness scores need Fitbit Premium. New users get a six-month trial.

Can it detect atrial fibrillation?

Yes, through the ECG app where the feature is approved. It is a screening tool, not a diagnosis, and results should be shared with a doctor.

How long does the battery last?

Fitbit rates it at six or more days. Heavy GPS and always-on display use shorten that, and fast charging gives about a day in 12 minutes.

Yes. It is rated 5 ATM, so it handles pool swimming and showers, though it is not meant for diving.

Does it work with an iPhone?

Yes, it pairs with both iPhone and Android over Bluetooth, though some features vary by phone platform.

Is it good for serious athletes?

It covers GPS runs, cycling and swimming, but training load and recovery tools are lighter than on dedicated sport watches.
