The short answer
Choose Murph
Choose Murph if you want one place where a workout, a symptom, a meal pattern, a medical record, and your wearable data can be read together and turned into a plan you can revisit.
Choose Caliber
Caliber is the better fit if you want a free app for strength routines and tracking, or a paid one-to-one coach who reviews your form and customizes your training.
Can Murph and Caliber work together?
Keep your routine, completed sets, and form feedback in Caliber. Bring the plan to Murph when a lab result, a symptom pattern, an eating problem, or a schedule clash changes how it fits, and let Murph keep the outside tasks from slipping. Nothing connects the two, so the handoff is manual.

Material tradeoffs
- Caliber's paid coaching can be very personal, but you cannot see the price without booking a consultation.
- The free app gives you structure, but not the ongoing relationship you get with a paid coach.
- Murph reads more kinds of health data and logs sets too, but it has no human coach to review your form or bring a trainer's judgment to your exercises.
- The free app and the paid coaching tier do very different jobs. Compare the tier you would actually use.
Common questions about Murph and Caliber
Is Caliber really free?
The core strength app is free. One-to-one coaching is paid, billed month to month, and priced through a consultation rather than a public rate.
Does every Caliber user get a human coach?
No. The paid membership includes a human coach. The free app gives you tracking and coach-designed plans, but no personal coach is assigned.
How is Caliber different from Murph?
Caliber is built around strength training: routines and tracking in the free app, plus a trainer's feedback in the paid service. Murph also programs and logs lifting, but it has no human coach. Its strength is reading those workouts next to the rest of your health data and following up on what you agreed to do.
