Build daily habits for movement and focus with HIIT and Pomodoro. HIIT timer and Pomodoro timer in one app. A mind-and-body habit app that brings exercise, focus, and reflection together so they finally stick. Re:build turns the time you move your body and the time you focus deeply into a daily rhythm. ■ Body A HIIT timer that supports short, efficient workouts. PREPARE → WORK → REST, guided intuitively with color, sound, and haptics. ■ Mind A Pomodoro timer that builds a rhythm of focus and rest. Log the time you focus — studying, working, reading, meditating, and more. ■ Built to keep you going · Visualize Body and Mind progress with dual rings · Schedule exercise and focus with a weekly plan · Track your streak of consecutive days · Apple Health sync for heart rate, calories, steps, and sleep · Record your daily condition with a quick reflection ■ Discover your patterns Small daily records reveal the trends in how you're doing. "I feel better on days I work out." "It's harder to focus when I sleep less." Your own patterns surface, little by little. ■ Re:build PRO For those who want to understand themselves more deeply: correlation analysis across exercise, focus, sleep, and mood, plus monthly and yearly reports.
