IronOS Strength is a free workout logger built for anyone serious about getting stronger. Log every set, track your progress, and measure your strength over time. Work with a coach, coach yourself for free, or let AI coach you. AI COACHING A real coach, built into the app. A guided intake learns your schedule, equipment, and goals, then IronOS writes your program using its own programming logic, powered by Claude. From there it reads your training log: your logged sets, your weight progression, your feedback on how each session went. Check-ins on fatigue, sleep, and life stress adjust your volume and intensity. Miss a day and your week reshuffles itself. DURABILITY SCORE A strength retention metric that measures how well you're holding onto your strength as you age. Built on established powerlifting standards including DOTS normalization and IPF age coefficients, the score tells you how much of your strength you're keeping, without ever needing to test a 1RM. LOG WITH PRECISION Pre-calculated warmups, automatic plate math, and RPE-based autoregulation. IronOS shows you exactly what to load, tracks your rest, and captures every rep. No spreadsheets, no guesswork. TRACK WHAT MATTERS IronOS tracks PRs automatically across every rep range, so a 5-rep best counts as much as a new single. The Progress tab charts your top sessions over time for every tracked lift. COACH INTEGRATION Working with a coach? They see every set as you log it. They can add notes to individual exercises, leave session-level feedback, and review your form check videos. All in one place. FORM CHECKS Record and upload videos mid-workout with full context attached. Your coach reviews them alongside your sets, weights, and RPE, not in a separate thread. BUILT FOR BARBELL TRAINING Configurable bar weights, plate inventory, cable stack settings, and deadlift start weight. Equipment that matches your gym, not a generic default. APPLE HEALTH Sync bodyweight automatically. Your Durability Score stays current without manual entry. Built for lifters who care about the long game. SUBSCRIPTION IronOS is free to use. AI Coaching is an optional auto-renewing subscription: free for 14 days, then $7.99/month. Payment is charged to your Apple ID account when the free trial ends. Your subscription renews automatically unless canceled at least 24 hours before the end of the current period. Cancel during the trial and you won't be charged. Manage or cancel anytime in your Apple ID account settings. Terms of Use: https://ironos.app/terms Privacy Policy: https://ironos.app/privacy
