Why it matters
Smart ring maker Circular on Thursday unveiled its upcoming Ring 3 series, which consists of a Pro model and a Slim option. Both of the smart rings will feature an integrated NFC chip for contactless payments, vibrating alerts for alarms and reminders, and more.
Who is affected
The Ring 3 Pro features a slimmer design than its predecessor and comes with FDA-cleared ECG for AFib detection, blood pressure trend tracking, glucose tracking, advanced sleep analysis, and comprehensive biometric monitoring. The ring offers up to 12 days of battery life, up from seven days on its predecessor.
What to watch next

Developer Action Items
- ☐ Diff the official changelog for Circular unveils Ring series before you bump — APIs, defaults, and removed flags only.
- ☐ Install through the vendor's documented channel in staging; keep a one-command rollback and time-box the canary.
- ☐ Grep your repo for old flag names, lockfile pins, and plugin versions that the notes mark as breaking.
- ☐ Prefer the first patch cut over the day-zero tag unless you have a reason to be on the leading edge.
- ☐ If TechCrunch did not name a region, plan, or SKU, screenshot the official availability line before you promise it to users.
