Build muscle and get stronger with a customized workout plan. Forge is a personal trainer that builds every strength training session around you: your fitness goals, your schedule, your experience, your equipment, your injuries. Home workouts or gym days, the plan fits the equipment in front of you and adapts every week as you progress. Ask your coach anything, any time. Form checks mid-set. The 7am question about training on five hours of sleep. Answers come back in seconds, from a coach that remembers everything you tell it. Other apps ignore questions or email back a day later. A human trainer charges $75-150 an hour. A year of Forge costs less than that. Every rep gets logged, every PR recorded. Whether you train to build muscle or lose weight, watch your progress climb with strength trends for every lift and a body weight chart, all on a dashboard you can customize. Every exercise comes with step-by-step instructions and a visual demo. Download Forge today and start your free 7-day trial.

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. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period; manage or cancel anytime in your Apple ID settings.
