Screenless fitness bands have gone mainstream. WHOOP built the category around recovery, strain, and sleep coaching, and charges a membership to use it. Google’s Fitbit Air arrived in May 2026 at a one-time price of about $100, with no subscription needed for its core tracking.
This review-style comparison covers specs, price, release dates, weight, functionality, subscriptions, and popularity, so you can decide whether the cheaper newcomer or the established specialist is better for you.

Release Dates
- WHOOP 5.0 and WHOOP MG: launched in May 2025 and replaced the WHOOP 4.0.
- Fitbit Air: announced in early May 2026 and available from May 26, 2026 in the US and about 20 other countries, including the UK, Canada, Germany, France, Japan, and Australia.
Price and Subscriptions
This is the biggest difference between the two.
Fitbit Air
You pay about $100 once for the band. Core tracking is included without a subscription: heart rate, heart rate variability, sleep stages, SpO2, stress score, and AFib alerts. The purchase includes three months of Google Health Premium, which adds AI coaching and deeper insights and costs about $10 per month afterward. You can keep using the band without it.
WHOOP
You cannot use a WHOOP strap without a membership. At launch, the tiers were:
- One: $199 per year, with WHOOP 5.0
- Peak: $239 per year, with WHOOP 5.0, the wireless charger, and extras such as Healthspan and a Stress Monitor
- Life: $359 per year, with WHOOP MG, including ECG and Blood Pressure Insights
Cost Over Five Years
A Fitbit Air costs roughly $100 over five years if you skip Premium. WHOOP Life at $359 a year comes to about $1,795 over the same period, and even the One tier adds up to roughly $1,000. If you pay for Google Health Premium at $10 a month, Fitbit’s total rises to about $700, which is still lower.
Weight and Design
Fitbit Air weighs just 12 grams, less than half of WHOOP’s 27 grams, and it is designed to be easy to forget you are wearing, even in bed. WHOOP 5.0 is about 7 percent smaller than the WHOOP 4.0 and offers the SuperKnit band and other accessories. Both have no display, so you check your data in the phone app.
Battery Life
WHOOP lasts up to 14 days between charges and charges while worn. Fitbit Air lasts about 7 days, and a 5-minute quick charge provides roughly a day. A full charge takes about 90 minutes using a magnetic USB-C charger. WHOOP wins on endurance, though neither band needs daily charging.
Sensors and Functionality
Fitbit Air
- Optical heart rate sensor
- 3-axis accelerometer and gyroscope
- Red and infrared sensors for SpO2
- Skin temperature sensor
- Sleep stages, stress score, and AFib alerts
- Google Health app with an AI health coach through Premium
WHOOP 5.0 and MG
- Sensors sampling 26 times per second
- Continuous monitoring of sleep, strain, recovery, stress, heart rate, blood oxygen, and skin temperature
- VO2 Max and more than 145 supported activities
- Healthspan features such as WHOOP Age and Pace of Aging on higher tiers
- FDA-cleared ECG and Blood Pressure Insights on WHOOP MG (not intended for diagnosis or treatment)
WHOOP generally goes deeper on training analytics and recovery coaching, while Fitbit Air covers the essentials at a much lower price.
Popularity
WHOOP reports more than 2.5 million subscribers, annual revenue reported at about $1.1 billion for 2025, and a valuation above $10 billion. Fitbit has a far larger historical user base, reported at more than 30 million, though those users are spread across many different devices. Screenless wearable sales grew by roughly 88 percent between 2024 and 2025, and analysts expect Fitbit Air’s low price to pull casual users away from WHOOP. Serious athletes who rely on WHOOP’s analytics are less likely to switch. Because Fitbit Air is newer, its sales figures are not yet as well established as WHOOP’s.
