Iron Diary is a workout log built for lifters and runners who hate clutter. Track every set, every rep, every run — then watch your body actually change. STRENGTH TIER SYSTEM Every muscle gets a tier: Beginner, Novice, Intermediate, Advanced, Elite. Bench, squat, deadlift, OHP, row, plus 30+ other lifts including dumbbell variants. Calibrated against published strength standards. Tap any muscle to see your last PR, a 90-day score sparkline, weekly volume, time-to-next-tier estimate, and exercises you haven't tried yet. IRON DIARY WRAPPED A story-style monthly recap of your training — total volume, biggest PRs, muscles that leveled up, longest streak, and a tier card to share. Auto-prompts at the start of each month. Save and post to TikTok or Instagram. RUNNING + GPS Log runs with live GPS tracking — distance, pace, duration. Cardio lives alongside strength so your whole week is in one app. PROGRESSION Compare your starting body to today. See which muscles leveled up. Watch your strength score climb week by week. WORKOUT CONTAINERS Workouts are persistent — Push Day, Pull Day, Legs — not single dated sessions. Open one, log your sets, close it. The next time you do Push Day, your last weights and reps are right there. No clutter, no calendar gymnastics.
