Iron Will is a workout tracker for everyday people who train — not just for people who already know what they are doing. Log your sets in seconds. See whether you are actually improving. Find out which muscles are recovered and which still need a day. No account, no sign-up, no setup — it works the moment you open it, even offline. FREE, AND STAYING FREE • Unlimited workout logging — the thing you came for is never paywalled • The full exercise library • Automatic rest timer and live workout volume • Personal-record detection • Built-in plate calculator • The 4-week starter program • Your last 30 days of history WHAT MAKES IT DIFFERENT • Today's Focus — Iron Will reads how recovered each muscle group is and tells you what to train today, in plain English: "Chest, shoulders and triceps are ready. Give your back and legs another day." • Next Target — for every lift it estimates your one-rep max and hands you the exact weight and reps to beat next session, tuned to whether you are training for strength, muscle or endurance. • Recovery Brain — a live muscle map showing what is fresh and what is still rebuilding, so you train smart rather than just hard. PRIVATE BY DESIGN • Works fully offline. No login, ever. • Your workouts are stored on your phone. They are never uploaded to us, sold or shared. • Save a backup of your full history to a file whenever you want — it is your data. • Anonymous crash reports and usage statistics, including your setup answers, help us fix problems and improve Iron Will. They never include your workouts. START IN UNDER A MINUTE Answer three plain questions — your goal, your experience and how many days a week you can train — and Iron Will builds you a real Day-1 plan. No account gate. No credit card. IRON WILL PRO — OPTIONAL, AND YOURS TO OWN Pro adds the depth: the Recovery Brain and Today's Focus, your next-session targets with an estimated one-rep max, progress charts for every exercise, unlimited routines (free keeps 3), and your full workout history (free keeps 30 days). Choose how you pay for it. There is a monthly plan, a yearly plan that costs less per month, and — unusually in this category — a one-time purchase that never renews and has nothing to cancel. Most apps like this only rent. You can buy this one. Free stays free either way. Iron Will is a training log, not medical advice. Talk to a doctor before you start or change a training program.

Verdict
The clearest difference is in-app purchases: Aurelys at none against Iron Will's 3. Aurelys also leads on update cadence (daily vs every 4 months). On price, ads, device support and iOS requirement there is nothing between them.
