On Program is a personal strength-training app that actually adapts to you. Answer a short setup and it builds a custom program around your goal, experience, equipment, and any injuries, then rebuilds it every week from how you really trained. No spreadsheets, no guesswork. TRAINS LIKE A REAL COACH - Your plan adjusts weekly using RPE (how hard your last set felt), so the weight is always right for you. - First week is a "baseline" — pick weights by feel and the app dials in your real numbers from there. - Beat your reps at an easy RPE and it adds weight automatically. Struggle, and it holds steady. LOG IN SECONDS - Do your sets, then log just the last one. That's it. - Built-in rest timer, plate calculator, and how-to cues for every lift. - Swap any exercise you don't like or can't do. A COACH IN YOUR POCKET - Ask anything, form, nutrition, motivation, why your plan looks the way it does. - Tell it "make my workouts shorter" or "4 sets instead of 5" and it actually changes your program. BRING YOUR OWN PLAN - Already have a plan from a coach? Paste it, snap a photo, or upload a PDF and On Program will run it for you. STAY MOTIVATED - Streaks, levels, and badges that reward showing up. - Track your estimated 1RM, weekly volume, and every personal record. - Add friends, race streaks, and keep each other on program. The only rule: stay on program. Download it, log your first session, and let it build around you. On Program provides general fitness guidance and is not a substitute for professional medical advice. Talk to a doctor before starting any new exercise program. Subscription: On Program Pro unlocks the full app — Monthly $14.99/month or Annual $69.99/year, with a 7-day free trial.
