Spin Timer: Random Interval

What if you never knew when the timer would end? Spin Timer is a random interval timer that removes the one thing sabotaging your workout — knowing how much time is left. Perfect for HIIT, gym circuits, meditation, and focus sessions. Set a minimum and maximum time. Hit START. The app picks a random duration within your range and counts down — without showing how much is left. No peeking. No mental math. Just effort, until the signal sounds. WHAT SPIN TIMER OFFERS: * Spin the wheel — set MIN and MAX, Spin Timer does the rest.
