Masso is your personal AI coach — chat about how you want to train, and it builds your weekly routines around your goals, equipment, and schedule, then guides you through every set. CHAT WITH YOUR AI COACH • Ask in your own words: "more chest, less legs", "dumbbells only", "keep sessions under 45 minutes" • Coach combines your profile, training history and a 900+ exercise library to build your week — then refines it turn by turn • # prompt templates with fill-in-the-blanks; long-press any exercise to swap it • Browse hand-picked Classic programs (5×5, PPL and more), or import a routine straight from a screenshot of any other app TRAIN WITH THE PLAYER • Set-by-set guidance: sets, reps, weight, rest countdowns, quick adjustments • Fix logged sets right from the rest screen, undo mis-taps, finish early with full stats • Progress survives locking your phone or switching apps; Apple Watch shows live heart rate and calories PROGRESS & INSIGHTS • Insight charts, a weekly AI summary, and strength trends per lift • Muscle recovery map — see what's fresh and what needs rest at a glance • Training calendar, week streaks, PRs, and shareable workout cards 900+ EXERCISE LIBRARY • Muscle diagrams, equipment filters, variant grouping, demo videos • Create your own exercises; smart search understands aliases and equipment names YOUR DATA, YOUR DEVICE • Workouts are stored on your device; optional Apple Health sync • No account required, no ads

  • This app hasn’t received enough ratings or reviews to display an overview.

This update sharpens accuracy and polish: • Workout history and Repeat now reflect the edits you make mid-session — a deleted exercise no longer inflates your set count. • The Coach tab shows a quick snapshot of your training preferences, with one-tap access to adjust them or view your generated routines. • Various refinements and fixes throughout.
