Buy the Fitbit Air if you want no screen, the lowest price, and a band you can sleep in. Buy the Fitbit Charge 6 if you want GPS, an ECG, tap-to-pay and a display on your wrist. The Air is the 2026 screenless tracker at $99. The Charge 6 is the 2023 AMOLED band, still on sale at a $159.95 list and often discounted. Google did not replace the Charge when it shipped the Air. It added the other answer.
How the Air feeds rewards is Fitbit Air rewards. The screenless field around it is best screenless fitness trackers.
Short verdict: Air for sleep, steps and a week of quiet tracking. Charge 6 for runners who want a map on the wrist and for anyone who will actually read notifications on a band. If the Charge 6 is on sale near $99, the screen becomes almost free. If you hate screens at night, the sale does not matter.

The screen is the whole decision
The Air is a pebble. Stats live on the phone, which is why it can be this light and why a night of sleep does not include a glowing rectangle. Google's pitch, and the reason it sits in our screenless roundup, is the Whoop shape without the membership: heart rate, sleep stages, SpO2, skin temperature, automatic activity, AFib alerts, core features in the free Google Health app. Premium coaching is optional. You do not need it for the hardware to function, and you do not need it for Fitcoin to read a workout that reaches Health Connect.
The Charge 6 is a small watch that refuses to admit it. Built-in GPS means a run without the phone. The AMOLED face shows pace, heart rate and notifications. ECG and Google Wallet are the features the Air deliberately left out. YouTube Music controls and a few Google apps sit on there too. None of that makes it a Pixel Watch. It makes it the right Fitbit if you look at your wrist during the workout. Turn always-on off if you want the week-long battery Google prints on the box. GPS days are shorter. That is physics, not a defect.
Sleep and the nightstand problem
Both can be worn overnight. The Air is the one built for it: less bulk, nothing to light up when you roll over. The Charge 6 sleeps fine for a lot of people and badly for the people who bought a screenless band on purpose. If you already take a watch off at night, neither Fitbit fixes a habit. If you want the sensor that stays on, start with the Air unless GPS is non-negotiable, in which case charge the Charge 6 beside the bed and accept the trade.
Price, including the sale trap
At list, the Air is $60 cheaper and newer. In practice the Charge 6 has been discounted hard because it is three years old, and a $99 Charge 6 against a $99 Air is a feature comparison, not a budget one. Do that maths on the day you buy. Do not do it from a 2024 review. Google Health Premium is a separate subscription on both and is not required for steps, sleep or heart rate. Three months of Premium have been bundled with Air launches. Treat the trial as a trial.
Who should buy which
- Fitbit Air if the job is all-day heart rate, sleep, and not looking at your wrist. Pair it with your phone for GPS.
- Charge 6 if you run outside and you want the map on the band, or you want ECG and tap-to-pay in a Fitbit price.
- A proper watch if you wanted apps, store payments beyond Wallet, and a screen you use all day. The Charge 6 will feel cramped. The Air will feel mute.
- Polar Loop or Hume if you wanted Whoop-style recovery words more than Google's health app. Those comparisons start at Polar Loop vs Fitbit Air.
Frequently asked questions
Is the Fitbit Air better than the Charge 6?
The Air is better if you want no screen, a lighter band, a lower list price and a tracker designed for sleep. The Charge 6 is better if you want built-in GPS, an ECG, tap-to-pay and a display. They are different products, not a simple new-versus-old ranking.
Does the Fitbit Charge 6 have GPS and the Air does not?
Yes. The Charge 6 has built-in GPS. The Air relies on your phone for mapped runs. That single feature is why a lot of runners should ignore the Air even though it is newer.
Do I need Google Health Premium for either band?
No. Core heart rate, sleep and activity work without it. Premium adds Google's coaching extras. Fitcoin's FitScore and partner rewards do not require that subscription either, as long as the activity reaches Health Connect or Apple Health.
Should I wait for a Charge 7?
Buy for the features you need this month. The Air is the new hardware. The Charge 6 is the screened Fitbit Google is still selling. A future Charge would have to add something you cannot get by owning one of these two. Rumours are not a battery.
Method and sources: Written 21 September 2026 from Google's Fitbit Air specifications (May 2026, about $99.99 / £84.99, about 12 grams, up to 7 days, 5 ATM, no GPS, no ECG, AFib alerts, Google Health) and Fitbit Charge 6 specifications (September 2023, $159.95 / about £139 list, AMOLED, built-in GPS, ECG, NFC, 5 ATM, battery up to about 7 days and shorter with always-on or GPS). Sale prices move. Regional ECG and irregular-rhythm clearance differs. Confirm the box. Not medical advice.
