Sets Gym Tracker vs IronOS

Log your lifts in seconds. See whether you're actually getting stronger. Sets is a strength training tracker built for people who lift seriously and want their numbers to mean something. Log weight, reps, and RIR without fighting the interface, then get analytics that tell you what's working and what you've been avoiding. BUILT FOR THE GYM FLOOR Logging a set takes two taps. Your last session's numbers sit right there, so you always know what to beat. Rest timer runs on your Lock Screen and in the Dynamic Island, so your phone stays in your pocket between sets. Works fully offline and syncs when you're back on signal. KNOW WHERE YOU STAND - Muscle heat map showing exactly what you've trained and what you've neglected - Strength trends and estimated 1RM per lift and muscle group - Momentum score telling you if you're building, holding, or sliding - PR journal, milestones, and monthly reports TRAIN WITH A PLAN Answer a few questions and Sets builds a split around your schedule, your equipment, and any injuries you're working around. Athlete Mode builds sport specific training with explosive work programmed in. Save templates, repeat past sessions, and let warm-up sets generate themselves. SWITCH ON THE FLY Machine taken? Shoulder complaining? Tap any exercise for ranked alternatives that match the muscle worked and the equipment you actually have in front of you. BRING YOUR HISTORY Import your full log from Strong, Hevy, or StrongLifts 5x5. You don't lose years of work to switch apps. Supersets, dropsets, cluster sets, unilateral work, bodyweight and weighted variants, plyometrics, timed drills. 290+ exercises built in, plus your own.

Train for the next twenty years, not the next twelve weeks. IronOS is a free strength training log for lifters who measure progress in years — pre-calculated warmups, automatic plate math, and RPE-based autoregulation. Chase PRs while they're coming, and track what you're holding onto when they slow down. Work with your coach, coach yourself for free, or let AI coach you. 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. Mark a set as it felt and the app tells you whether you were dialed in or overshot. No spreadsheets, no guesswork. DURABILITY SCORE An age-graded strength standard — the thing masters runners have had for forty years and lifters never got. Built on DOTS normalization and IPF age coefficients, the same standards powerlifting federations use, it shows how your current strength compares to an age-adjusted benchmark without ever testing a 1RM. A second measure of progress, one that keeps moving even when your PRs don't. BUILT FOR BARBELL TRAINING Configurable bar weights, plate inventory, cable stack settings, and deadlift start height. Equipment that matches your gym, not a generic default. TRACK WHAT MATTERS PRs tracked automatically across every rep range — squat, bench, deadlift, and every accessory you log. The Progress tab charts your top sessions over time for each lift. AI COACHING A guided intake learns your schedule, equipment, and goals, then IronOS writes your program — its own programming logic, powered by Claude. It reads your actual training log: your logged sets, your weight progression, your feedback on how each session went. Check-ins on fatigue, sleep, and life stress adjust volume and intensity. Miss a day and your week reshuffles itself. Free for 14 days. WORKING WITH A COACH Your coach sees every set, adds notes to individual exercises, leaves session feedback, and reviews your form checks — all in one place.
