Nemku Strength builds your training plan, adjusts it to what you actually do, and stays out of your way while you lift. Or, log your own workouts freely if you don't want to follow a plan. Proper Form videos available with every exercise. YOUR PLAN, NOT A TEMPLATE Answer a few questions — or bring your own split — and get a week of sessions matched to your days, your equipment, and your level. Skip a session, crush a session, pick up a nagging shoulder: the next week adapts. Emphasize a muscle group and the plan makes room for it without wrecking the rest. YOUR WORKOUT, SET BY SET The workout player runs your session one set at a time: log a set, start your rest, and the next one's ready. A rest timer rides your Lock Screen and Dynamic Island so you can put the phone down between sets. Prefer typing? Quick-log understands "bench 3x8 185" or "ran a 5k in 25 minutes" and files it correctly. SEE THE WHOLE PICTURE The muscle balance board shows which groups are getting work and which are falling behind, week by week, at a glance. Progress charts track your lifts, estimated one-rep maxes, and personal records over time. PLAYS NICE WITH APPLE WATCH Workouts you record on Apple Watch show up in your log with heart rate, calories, and elevation. Finished sessions sync back to Apple Health and count toward your rings. MEET CAPI A deadpan capybara lives in the app. Capi doesn't cheer, doesn't nag, and doesn't send notifications at 6am. Capi mostly just believes in you, quietly. YOURS, PRIVATELY No account. No ads. No analytics. No feed. Your training log lives on your phone and in your own private iCloud. The developer has no server and cannot see your data. Health metrics stay on-device, full stop. More on-device Apple Intelligence integration coming with iOS 27. NEMKU PRO Manual logging is always free. Log your own workout, quick log, history, timer, Apple Watch import, iCloud sync, and progression recommendations on the lifts you log. Nemku Pro unlocks the part that builds and steers the plan: The workout player, plans crafted by both the latest and old school training science, recommended exercises and custom splits, Capi's Kitchen, muscle-focus emphasis, rotation edits, and custom exercise swaps. • Nemku Pro Annual — $39.99 per year, starting with a 14-day free trial • Nemku Pro Monthly — $4.99 per month Payment is charged to your Apple ID at confirmation of purchase. Your subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours of the end of that period. Manage your subscription or turn off auto-renew in your Apple ID account settings after purchase. Any unused portion of a free trial is forfeited when you purchase a subscription. Nemku Strength is built by one lifter, for lifters. Download it, get to a dumbbell, and log a set.
