About

SkillMax

Features
Read full description

Most training apps hand you a workout. SkillMax hands you a path to a specific skill — and shows you exactly which step you are standing on. Choose the move you want: muscle-up, front lever, planche, handstand, pistol squat, one-arm pull-up. SkillMax breaks it into a ladder of progressions and starts you at the rung that matches what you can do today. No guesswork about whether you are "ready" for the next step. BUILT AROUND SKILLS, NOT RANDOM WORKOUTS • 15 skill trees covering the core calisthenics movements • 84 progression steps, each with a clear standard for moving up • 140+ exercises with video demonstrations and form cues • Every step tells you what to hit before you advance A PLAN THAT RESPONDS TO YOU Your week is generated from your goal skill, your training days, and your session length. Log what you finish and the plan adjusts volume moves with your progress, and a step you keep missing gets more support work rather than more attempts. • Weekly plan built around your chosen skill • Sessions sized to the time you actually have • Progression standards you check off yourself — honest input, honest plan • Missed a day? The week shifts instead of deleting the workout TRAIN WITH STRUCTURE • 12 warm-up and mobility routines matched to the session ahead • Rest timers between sets • Injury-aware prep work if you flag a past problem area • Session history, streaks and personal records NO GYM REQUIRED A pull-up bar and a floor cover most of the catalog. Parallettes and a resistance band open the rest. No machines, no membership. SUBSCRIPTION SkillMax is a subscription app. Full access to skill trees, adaptive weekly plans, the exercise library and progress tracking requires an active subscription, offered monthly or yearly — the paywall shows the exact terms and price for your region before you confirm. Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours prior to the end of the current period. You can manage your subscription and turn off auto-renewal in your Apple ID Account Settings after purchase.
