Kairos
Read full descriptionHide full description
Most timers tell you exactly when they end. Kairos does not. Set a minimum and maximum duration, start the timer, and Kairos chooses a random moment in between. You know the range. You do not know the exact finish. That simple twist makes Kairos useful anywhere timing should stay unpredictable. USE KAIROS FOR - Meditation: sit without watching the clock - Exercise: hold effort without bracing for the last seconds - Study sessions: add flexible focus or break intervals - Interval training: Auto Repeat randomises every set so you never anticipate the next round - Party games: perfect for Hot Potato, Musical Chairs, and other pass-it-fast games FEATURES - Random timer between your chosen minimum and maximum - Clean countdown interface designed for iPhone - Hide Time Display for a more focused, less predictable experience - Auto Repeat, Overtime, and Auto Stop modes after the timer ends - Label your timers for quick recognition in Recents - Choice of built-in alarm sounds - Haptic feedback when time is up - Recents for quickly restarting favorite timer setups - Light, Dark, and System theme - No ads or sign-up required Kairos is built for the moments when exact timing gets in the way and a little uncertainty makes the experience better.
