Strength Log: Track Your PR

A workout log that shows your personal best the instant you type an exercise name.

• Just enter the exercise, weight (kg), and reps • A trophy badge makes a new personal best obvious at a glance • See each exercise's weight trend on a line chart, grouped by day

Built for lifters practicing progressive overload, and anyone tired of scrolling back through history just to remember "what did I lift last time?" No exercise templates, routines, or HealthKit sync yet — a deliberately simple, free-text design.

Free for up to 30 sets. A one-time ¥300 (or local equivalent) purchase unlocks unlimited sets. No subscription.
