About

Kairos

Features
Read 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.

The main upside with this timer is that it is simple and is mostly preset buttons versus dial based. And it doesn't save all your past timers if that annoys you like it does me.
