About this app
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.

Templates & history
Reusable workout templates and a dated history of completed sessions.

Distinct from Form Coach (live form cues), which doesn't l…
