Founder & app description

Crucible was built by a seasoned software engineer who was in the best shape of his life when a rare and severe illness - herpes zoster duplex bilateralis, a form of shingles that strikes both sides of the body at once - left him disabled and forced to start over.

Rebuilding taught him what no tracker ever had: real strength does not come from pushing harder every day. It comes from listening to what the body can do today, and meeting it there. So he set out to build the training partner he always needed - one that reads your readiness, adapts to your goal, time, equipment, and location, and makes purposeful strength training feel within reach at any age.

App description (boilerplate)

Crucible is an iPhone and Apple Watch strength training app that decides what to train next. It builds each workout around your goal, available time, equipment, location, muscle focus, readiness, and progress, then guides every set from your wrist. The first 3 workouts are free; 7-day and 14-day free trial options unlock full access.
