What Ironlog does
Ironlog is a fast, no-nonsense strength-training logbook built around progressive overload. Start a workout, log each set in a tap or two, and Ironlog shows your last performance on that lift so you always know the weight or reps to beat. It tracks every personal record automatically — heaviest set, estimated one-rep max, best volume — and a built-in plate calculator tells you exactly which plates to load on the bar.
No account. No subscription. No social feed. Just your training history, on your phone, forever.
• One-tap set logging with last-session reference • Automatic PRs: top set, estimated 1RM, volume • Plate calculator for any bar and target weight • Reusable workout templates (Push/Pull/Legs, 5x5, your own) • Lift history and trend per exercise • Fully offline and private

- Plate calculator — Given bar weight and target, compute the plate stack per side.
- Templates & history — Reusable workout templates and a dated history of completed sessions.

What makes it different
A focused, offline strength log with automatic PR detection, estimated 1RM, and a built-in plate calculator and reusable templates — no subscription, no account, no social feed, unlike Strong/Hevy which gate history or features behind a paywall and cloud sync. Distinct from Form Coach (live form cues), which doesn't l…
Who it's for
Anyone who wants honest tracking without a coach, a subscription, or a streak guilting them at 11pm.
