Calendar notifications are easy to swipe away. OnTimer turns your calendar into real alarms, so a missed notification doesn't become a missed meeting, or a missed flight. Connect your Google, Outlook, or Apple Calendar once, and OnTimer does the rest: a persistent alarm when it's time to act, a Time to Leave alert when it's time to head out, and now Time to Fly for every flight on your calendar. NEW: TIME TO FLY Every flight on your calendar gets an alarm when it's time to leave for the airport. OnTimer recognizes flights your email and travel apps add to your calendar, or just put the airport code, like JFK, in an event's location. Your leave time combines airline-recommended arrival times (2 hours domestic, 3 hours international) with your drive, parking, and whether you're checking a bag. Connecting flights don't get a second alarm, and you can adjust any flight from its card. CUSTOM ALARM SOUNDS Make your alarms your own. Choose a sound for your main alarm and another for Time to Leave alerts, or give one event its own sound. Preview every sound for free. More sounds are coming soon. HOW IT WORKS OnTimer uses your calendar as the source of truth. When your schedule changes, your alarms stay in sync, so you never create or maintain alarms by hand. Unlike notifications that disappear after a swipe, OnTimer's alarms keep reminding you until you dismiss them. High Alert can ring through Silent mode and Focus on iOS 26.1 and later. Prefer quieter alerts? Medium Alert respects Focus. TIME TO LEAVE ALERTS For events with a location, OnTimer watches traffic and tells you exactly when to head out. Choose your travel mode and add a departure buffer.

Meds, training, client calls, wind down, all of it. Claude writes the day to my Google Calendar and that used to be where the system broke, because iOS calendar notifications are useless. Quiet banners you swipe away without looking. I had a perfect schedule sitting in my calendar and still missed half of it. OnTimer fixed it. It reads my calendar and automatically creates a real alarm for every event. Not a notification. A loud alarm that actually cuts through. I don’t build alarms manually. I don’t maintain two systems. Claude writes the plan, OnTimer turns it into sound, and I just live my day. If you searched “Google Calendar to iPhone alarm,” “convert calendar to alarms,” “AI calendar alarm,” “Claude calendar sync,” or “ADHD calendar alarm app,” this is it. The developer is also a real human (I won’t say his name for privacy) who actually cares. Responsive, fast, works the problem with you, ships fixes. Almost extinct in the App Store right now. Setup took two minutes. Loud alarms. Customizable lead time. If you use AI to plan your life and you’re on iPhone, OnTimer is the piece that closes the loop. ### 5/5 — Keeps me on time *2026-04-02* My grandfather always told me that if you’re on time, you’re five minutes late.
