The short answer
Choose Murph
Choose Murph if the real question involves sleep, symptoms, training, records, stress, or whether the logging is still worth it. Murph helps you shape and revisit the plan, but it is not an adaptive calorie algorithm.
Choose MacroFactor
Pick MacroFactor when you want an expenditure estimate and weekly calorie or macro adjustments built from steady intake and weight data.

Material tradeoffs
- The adaptive model gets better as food and weight are logged consistently and accurately.
- There is no lasting free tier once the trial ends.
- The app deliberately ignores daily wearable calorie estimates when setting food targets. That removes a noisy input but keeps the program narrow. Murph can talk through that tradeoff, but it does not estimate expenditure or set weekly calorie and macro targets.
Common questions about Murph and MacroFactor
How does MacroFactor adjust a nutrition plan?
It estimates your energy expenditure from how logged intake lines up with weight change. Each week it proposes updated calorie and macro targets. Missed targets are treated as data, not as a moral failure.
Does MacroFactor use wearable calorie burn in its algorithm?
No. Its core expenditure model is built on food and weight data on purpose. A watch's daily calorie estimate does not move your targets.
When would Murph add something to MacroFactor?
MacroFactor turns steady food and weight data into a focused body-composition program. Murph adds an ongoing conversation about what the model leaves out: competing health goals, symptoms, training, and whether the routine is sustainable. It does not replace the expenditure model or a clinician.
