30 seconds of work, and 10 seconds of rest. "Simple Timer" is a minimalist interval timer that fully automates your custom time cycles. Whether you're stretching, practicing yoga, meditating, or focusing on your daily routines, you no longer need to constantly tap your screen to reset the timer. It is designed purely as a tool to keep your focus unbroken from start to finish. Look at the screen, and you'll see a clean circle quietly visualizing the remaining time. Close your eyes, and Siri's voice feedback or soothing ambient sounds will guide you through phase transitions. Stripped of unnecessary features and flashy animations, it simply exists to organize your time beautifully. β–  Basic Features (Free) * Intuitive Setup: Easily input WORK, REST, and the number of SETS. * Soothing Sounds: Choose from relaxing ambient sounds (like Rain or Forest) or toggle transition sounds. * Voice Assistant: Siri will announce your sets and countdowns in English, allowing you to stay focused without looking at the screen. * Theme Colors: Available in Blue and Red.
