Questions and answers

Which is better for sleep tracking?
The Oura Ring 4. It tracks sleep stages, SpO2 and temperature trends and is comfortable to wear overnight. The Charge 6 tracks sleep too, but with less recovery detail.
Do I need a subscription for either?
Oura needs a paid Membership for full insights. The Charge 6 includes 3 months of Premium, then it is optional.
Which is better for running and gym workouts?
The Fitbit Charge 6. It has built-in GPS and shows your heart rate on gym equipment. The Oura Ring 4 has no GPS and no screen.
Is the Oura Ring 4 worth the extra money?
Only if sleep and recovery data matter more to you than a screen and GPS. At $188.97 versus $84.99 at eBay as of November 5, 2026, the Charge 6 covers basic fitness for far less.
Can I swim with them?
The Charge 6 is rated 5 ATM and is swim-proof. The Oura Ring 4 is water resistant, but Oura advises against wearing it in water.
