Frequently Asked Questions
5 questions
No. Fitbit's basic features (step counting, heart rate, workout tracking, sleep monitoring) work without any subscription using the free mobile app. The optional Fitbit Premium subscription ($9.99/month) unlocks advanced insights, personalized coaching, and exclusive content. WHOOP, by contrast, requires a $30/month subscription to access any analytics—the band alone provides no data without the app connection.
