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.
ShareTimers

Every timer app counts down for one person. ShareTimers counts down for everyone. Set a timer, tap share, and send the link to anyone. They see the exact same countdown, ticking live on their screen, in the app or right in their browser. No account, no sign-up, no invite to accept. SHARED, LIVE, AND EDITABLE A ShareTimers link isn't a screenshot of a timer. It's the timer. Anyone holding the link can add a minute, pause it, resume it, or rename it ā and everyone watching sees the change instantly. When the roast needs another ten minutes, whoever's at the oven adds them, and the whole table knows. SHARED STOPWATCHES TOO Counting up works the same way. Publish a running stopwatch, share the link, and everyone follows the same elapsed time and the same laps ā useful for races, drills, practice runs, and anything you'd otherwise be calling out splits for. NO ACCOUNTS. EVER. There's no login, no profile, and no friend list. Holding the link is the whole permission model. That means you can send a timer to someone who's never heard of this app and they're watching it two seconds later. WORKS EVERYWHERE iPhone, iPad and any web browser. People without the app just tap the link and watch the countdown on the web ā nothing to install. Links in Messages unfurl with a live preview, and tapping one opens straight to the timer if you have the app. NOTIFICATIONS THAT KEEP UP Get notified when your timer ends, even if the app is closed. If someone extends or pauses the timer, your notification reschedules itself automatically ā you're alerted at the real end time, not the old one. BUILT TO FEEL NATIVE Clean, familiar design that matches the system clock you already know. Timers and stopwatch in one place, recent timers a tap away, and nothing you have to learn. GOOD FOR ⢠Cooking together, one timer, everyone in the kitchen ⢠Laundry, dishwashers, and anything that's "done" for the household ⢠Workouts, rest intervals, and circuit training with a partner ⢠Study sessions, Pomodoro blocks, and focus sprints with a group ⢠Meetings, talks, and speaking slots where someone needs to see the clock ⢠Games, debates, and turn timers everyone can watch ⢠Kids and chores, without handing over your phone ⢠Races and drills, with shared laps on a shared stopwatch Set it once. Share it everywhere. Everyone stays on the same clock!
