A big update for VoltTimer. NEW • Workout Log (Pro): record any workout with its type, duration, intensity, muscle group, and notes — weights, cardio, HIIT, yoga, sports, even rest days. • A fresh new look across the whole app, in light and dark mode. • A redesigned timer with a glowing progress ring, tick marks, and a smooth color change between work and rest. IMPROVED • The timer keeps correct time and alerts you for each phase while your screen is locked. • Cleaner history, workouts, and settings screens. • Pro now unlocks automatically if you've already purchased it. FIXED • Restore Purchases no longer gets stuck loading. • Fixed the timer overlapping the controls on smaller iPhones.
