The short answer
Choose Murph
Choose Murph when a Circular result needs checking against your symptoms, records, and routines. Murph also helps you separate what the ring does today from what Circular says is coming, before you act on either.
Choose Circular Ring 2
Circular Ring 2 is the better fit if you want sleep, energy, and stress tracking from a ring, live measurements, a short ECG check, and core features with no forced subscription.
Can Murph and Circular Ring 2 work together?
Use Circular for the ECG check, sleep analytics, alerts, and Kira guidance available on your ring. Murph reads the data through Apple Health on iPhone, or you can share a result, and puts it beside your records and symptoms before you build a plan. Leave the unverified blood pressure and glucose promises out of that plan.

Common questions about Murph and Circular Ring 2
How much does Circular Ring 2 cost?
Circular Ring 2 was listed at $299, down from $349, and could be added to the cart when we checked on August 30, 2026. Confirm variant availability and the final price at checkout, since both can change.
Does Circular Ring 2 track blood pressure and glucose yet?
Not as far as we can confirm. Circular's official pages conflict, with product copy showing blood pressure trends while also calling blood pressure and glucose features upcoming, and the August 26 release notes describe both as upcoming or unfinished. General availability and whether either will cost extra are unverified.
Can I use Circular Ring 2 and Murph together?
Yes. There is no direct Circular connection, but if the ring syncs to Apple Health on an iPhone, Murph reads that data. Use Circular for the measurements and Kira features that exist today, and use Murph to weigh a result beside your records, symptoms, and routines, choose a step that does not rely on an unverified feature, and review what happened.
