No More Pressure Marks
Feedback from long-term wearers is consistently positive about the new flat sensor windows. Earlier versions pressed raised plastic bumps against the skin, often leaving marks or causing irritation after hours of wear. The Gen 4 removes those bumps entirely, and many sensitive users report they can now wear the ring comfortably through the night without the previous discomfort.
Fewer Gaps in the Overnight Data
When the ring rotates during sleep, earlier models sometimes lost signal. The Gen 4 uses multiple sensor paths and switches between them automatically when contact weakens. This keeps sleep stage data more continuous and reduces the gaps that used to appear in overnight tracking for many users.
The Fee Nobody Asked to Keep Paying
Even with the hardware improvements, the subscription requirement remains unchanged. Owners still need to pay monthly to access the full range of insights beyond basic daily scores. As more subscription-free rings enter the market, this ongoing cost continues to be one of the most common sources of frustration after the first few months of ownership.
Battery Life vs. a Scratch-Prone Finish
Battery life holds up well for most users, often reaching close to a week on a single charge. The titanium finish, however, shows visible fine scratches relatively quickly when the ring comes into contact with keys, weights, or other hard surfaces. Many owners end up being more careful with how they handle it to preserve the look.
Is It Worth the Monthly Cost?
If detailed algorithmic sleep and recovery data is a priority and you’re comfortable with an ongoing subscription, the Gen 4 offers clear improvements in comfort and tracking consistency. If recurring monthly fees for accessing your own health data feel unnecessary, there are now several strong alternatives that don’t require one.
