Rust Strength answers the question every lifter has mid-workout: how much should I put on the bar for the next set? And now it records your runs too. Log a set with the weight, the reps, and how hard it felt on the RPE scale. Rust Strength estimates your one-rep max from that, then suggests a weight for your next set aimed at reaching failure inside the rep range you chose. Every suggestion is rounded to a weight the machine in front of you can actually be set to, and each machine keeps its own history, so a hotel gym doesn't throw off what it knows about your home gym. LIFTING Weight suggestions after every set, with a plain-English reason for each one. Every set from last time shown while you log, top set in bold. Over 200 exercises built in, or add your own. Search forgives typos. Bodyweight, assisted and timed exercises: more reps, less assistance, or a longer hold to beat. Presets, and a generator that builds a session from the equipment you have and the muscles you haven't trained this week. A rest timer that starts when you save a set, counting down on your Lock Screen and in the Dynamic Island with your next set. RUNNING Record runs with GPS, with your phone locked: live map, distance, pace, splits and steps. Your time, distance and pace on the Lock Screen and in the Dynamic Island. Auto-pause at lights, and optional spoken updates every mile or kilometer. A summary for every run with pace and elevation charts. Edit the title or trim the start and end afterwards. Weekly and monthly distance, a weekly goal, and your fastest mile, 5K, 10K, half marathon and marathon. Save a route, run it again and compare your attempts. Enter treadmill runs by hand. PROGRESS AND FRIENDS Streaks, consistency, volume, time trained and personal records. Every activity counts toward your streak, and planned rest days keep it alive. A body chart of the muscle groups you trained this week, and a progress chart for every exercise. Tiered trophies from Wood to Legend for lifts, running, steps and more, plus XP, levels and badges. Show two favorites next to your name. A feed of friends' sessions and runs that you can react to, and a leaderboard for streaks, weight lifted, workout time, distance run and more. Share a card after any workout or run, to Instagram, Messages or Photos. Track 40+ other activities, from pickleball to skiing. DESIGNED TO ASK FOR LITTLE No ads. No analytics. No tracking. Rust Strength asks for an email address and a password so your training syncs, and collects nothing it doesn't need. Location is used only for runs you record and privacy zones you set. Friends see a summary of a session, never the individual sets, and a run's map only if you share it, with the start and end always hidden. Steps are shared only if you turn that on. Export everything you've logged, or delete your account and all its data, from inside the app at any time. IMPORTANT Rust Strength is a training log, not medical or professional coaching advice. It suggests weights from the numbers you give it and knows nothing about your health, injuries or experience. Warm up, use your own judgement, and stop if something hurts. Be aware of your surroundings when you run. Talk to a doctor before starting a new training program.
