Material tradeoffs
- Lark's shipped scale, glucometer, or blood pressure cuff and its CDC recognized program are things Murph does not offer. Murph reads your own connected meters and cuffs but ships nothing and runs no curriculum.
- Access depends on eligibility. Without a participating plan or employer there is no published way to buy Lark, and device perks can require engagement minimums.
- Lark's coaching stays within the enrolled program's scope and is not medical advice. Questions outside the program, and the errands around care, are where Murph fits.

Is the Lark coach a person?
The everyday coach is automated and available around the clock. Most programs also include live sessions with certified human coaches and a member community, and the home page notes that the digital coach does not provide medical advice.
