Material tradeoffs
- A countdown is a strong motivator for some people and a source of anxiety for others. Death Clock's own terms say it provides no medical advice, so the estimate is not a clinical prognosis.
- The web pricing page shows plans as an image, and the App Store lists ten different in-app purchases, so check what a given tier includes before paying.
- Murph offers no life expectancy model, no ordered blood panels, and no partner draw sites. It works with results you bring in.
Common questions about Murph and Death Clock
Is the Death Clock estimate accurate?
It is a model estimate from a 29 question intake and, if you add them, blood results and wearable data. Death Clock says it is built on longevity research, and its terms say it provides no medical advice. Treat the number as a motivational estimate, not a prognosis.
How much does Death Clock cost?
The web pricing page shows plans as an image, so the clearest figures are in the App Store: Digital Only at $49.99 per year, a Baseline blood package with a three day trial at $99.99, and memberships between $9.99 and $99.99 when reviewed.
Can Murph do what Death Clock does?
Partly. Murph does not estimate life expectancy or sell blood panels. It can read the blood results you upload, connect them with your wearables and records, and help you follow the plan you choose.
