About
Built for hypertrophy. Beat your last workout.
GROWTH is a training log for people working toward muscle growth and greater strength. Logging is a means to progress: one more kilogram, one more rep, one small step beyond your last session.
BUILD PROGRESSIVE OVERLOAD
Add weight, increase reps, or gradually build sets and total volume within your capabilities. GROWTH records those changes so your last workout can guide the next.
SEE YOUR LAST SESSION. LOG THIS ONE.
Track weight, reps, sets and drop sets alongside previous records and targets. Personal records, notes and a rest timer support your daily training.
CHECK PROGRESS WITH NUMBERS
Review training days in the calendar and follow weight, reps, volume and estimated 1RM. Pro adds category and detailed analysis to help you review trends and possible plateaus. Estimates are reference values, not guaranteed performance.
LOOK BEYOND THE NUMBERS
Has your body changed as your lifts improve? GROWTH Photos lets you compare your own progress photos over time. Record body weight and body-fat percentage, and turn a day's training into a GROWTH Card. These features document changes; they do not guarantee results.
USE YOUR RECORDS TO PLAN THE NEXT STEP
GROWTH AI helps you discuss your next weights, reps and training approach using the records and goals you choose to send. Before transmission, explicit consent explains the information sent through Supabase to OpenAI. You can decline and keep logging, or withdraw consent in Settings. Photos and audio are not sent to AI. Responses are reference information, not medical diagnosis or treatment.
START FREE. FOLLOW YOUR PROGRESS MORE DEEPLY WITH PRO.
Basic logging requires no user sign-in. Free includes 20 active exercises, one month of analysis, one progress photo per day and five lifetime AI requests.
As your training becomes more detailed and your records grow, GROWTH Pro provides:
• Unlimited active exercises, from bench presses and incline variations to flyes and dumbbell work.
• Full-history analysis across three months, six months, a year and beyond, plus category and detailed insights. Progress deserves a longer view.
• Five photo categories—front, side, back, arms and free—with one photo per category each day, up to five total.
• Up to 300 AI requests per month to explore the next step using your own records.
• Custom categories, CSV export and premium accent colors.
YOUR DATA AND ACCOUNT
Records and photos are stored primarily on your device. Optional Apple Health integration reads and writes permitted weight and body-fat data. Sign in with Apple can protect or restore your GROWTH account. Delete your account and applicable data from Settings; this does not cancel an App Store subscription.
