“Are you joining the meeting?” If you’ve ever gotten that message while you were sidetracked by an email, a task, or one more thing, OnTimer is for you. It’s easy to dismiss a calendar notification and lose track of time. OnTimer helps make sure that doesn’t turn into a missed meeting. OnTimer automatically keeps you on time. Connect your Google, Microsoft, or Apple Calendar once, and OnTimer does the rest—from an Early Warning before an important event to a persistent alarm when it’s time to act, and a Time to Leave alert when it’s time to head out. HOW IT WORKS OnTimer uses your existing calendar as the source of truth. When your schedule changes, your alarms automatically stay in sync—so you never have to create or maintain manual alarms. Unlike regular calendar notifications that disappear after a swipe, OnTimer uses persistent alarms that keep reminding you until you dismiss them, helping bridge the gap between noticing a reminder and actually showing up on time. High Alert helps important alarms reach you. On iOS 26.1 and later, it can ring through Silent mode and Focus/Do Not Disturb. Prefer quieter alerts? Choose Medium Alert to have OnTimer respect Focus. Want a heads-up first? Early Warning gives Pro users a lighter notification before the main alarm, so an important meeting or appointment doesn't sneak up on you. Need more time for one particular event? Adjust its main alarm and Early Warning timing without changing your defaults for everything else. Make your alarms your own. Pick sounds for your main alarm and Time to Leave alerts, or give one event its own sound.
