Timers & Alarms

The timer and alarm app you need — designed to keep you on track, whether you're cooking, working out, or managing your daily schedule. QUICK TIMERS & PRESETS Get a countdown running in seconds. In the timer list, tap the lightning bolt beside +, pick 1, 3, 5, 10, 15 or 25 minutes — or dial any duration — and tap Start: it runs at once and clears itself from the list once you're done with it. Or start from one of ten ready-made presets: Pomodoro, Pomodoro 50 / 10, HIIT, Tabata, Meditation, Power Nap, Green Tea, Boiled Egg, Box Breathing and Stretching. Each one explains what it's for, and you can edit it like any other timer. COUNTDOWN TIMERS Create multiple named timers with custom durations. Personalize each timer with its own color and alarm sound. Start, pause, resume, and stop timers independently. INTERVAL TIMERS Set up two alternating phases — perfect for HIIT workouts, Pomodoro sessions, or any activity with work and rest periods. Customize the name, duration, and alarm sound for each phase. Add an optional warm-up before the first round and a cool-down after the last — or rename the cool-down to "Long Break" for full Pomodoro sessions. REPEATING TIMERS Let timers repeat — a fixed number of rounds or endlessly until you stop them. Track your progress round by round. ALARMS Schedule alarms for specific times with flexible weekday recurrence. One-time alarms disable automatically after firing. Snooze with configurable durations. STOPWATCH A third tab counts up from zero — no duration, no alert, it simply measures how long something took. Take a lap with one tap and compare the laps in the list. A running stopwatch keeps going when you switch tabs, leave the app or restart your device, and it costs no battery: it remembers when it started instead of counting. While it runs or holds, it appears on the Lock Screen, in the Dynamic Island and on the Smart Stack of your Apple Watch, with Pause and Lap right there. The Stopwatch control starts it from Control Center, the Lock Screen or the Action button. WIDGETS & LIVE ACTIVITIES Control your timers directly from the Home Screen and Lock Screen. Small and medium widgets show your timers and alarms at a glance — start, pause, or stop without opening the app. The Quick Timer widget starts a countdown with a single tap and shows the ones already running. The Tomato Timer widget (small, medium, large) brings a classic kitchen-timer tomato to your Home Screen. Live Activities keep your countdown visible on the Lock Screen and Dynamic Island. SHORTCUTS & SPOTLIGHT Start a saved timer, set a quick one, stop a timer, ask how much time is left, move to the next round, or turn an alarm on or off — from Spotlight or as a step in your own shortcuts. You pick the timer from a list of your own. iPAD & iPHONE Duo On iPad and the large inner display of an iPhone Duo, timers and alarms sit in a grid, and the alarm list stays within reach beside the alarm you open. On an iPhone Duo, the timer detail and the stopwatch split at the fold. With a keyboard, shortcuts such as ⌘N for a new timer save you typing. 25 ALARM SOUNDS Choose from 25 distinct sounds — from gentle chimes to clear bells, plus four short ticks that suit fast interval work — and preview each one before you decide. FULLY CUSTOMIZABLE • Custom colors for visual distinction • Multiple sort options (name, duration) • Group active timers at the top of your list • Light, dark, or automatic appearance • Grid layout and a two-column detail view when there is room • VoiceOver support and Dynamic Type up to accessibility sizes PRIVACY FIRST All your data stays on your device. No analytics, no tracking, no accounts. Your timers are yours alone. Timers & Alarms is free to use. Love the app? Leave a tip to support independent development.
