Material tradeoffs
- Don't Die's score and leaderboards are motivating if competition works for you, but a single score can hide which habit actually moved your results.
- Its privacy policy and terms are hosted on Notion rather than on the product site, and the pages reviewed do not describe lab report uploads beyond biomarker tracking.
- Murph does not produce a composite daily score, a biological age estimate, or leaderboards, and it has no community events.
