OnTimer - Never be late

Auto alarms for every meeting

Features & Capabilities

Persistent alarms for every calendar event. Never miss meetings again. Connect once, get automatic alerts that don't disappear. Try free for 7 days

You glance at your calendar reminder, think "I'll join in 5 minutes," then suddenly realize the meeting started 20 minutes ago.

OnTimer solves this. It automatically creates persistent alerts for every meeting in your calendar—so you'll never lose track of time between the reminder and the actual event.

HOW IT WORKS Connect your Google or Microsoft calendar once, and OnTimer does the rest. No more manually setting alarms every morning. No more hoping you'll remember. Your meetings sync automatically, and OnTimer creates alarms that actually get your attention.

Unlike regular calendar notifications that vanish when you swipe them away, OnTimer's alerts stay visible and audible until you dismiss them. You're in control with custom settings for:

  • Recurring events – Automatically alarm for daily standups, weekly 1:1s, or any repeating meeting
  • Business hours – Only get alarms during work hours (paid feature)
  • Do Not Disturb – Respect your focus time when you need it

TIME TO LEAVE ALERTS For in-person meetings, OnTimer calculates exactly when you need to leave based on real-time traffic. Set your preferred transportation mode (driving, transit, or walking) and add a buffer time. OnTimer monitors traffic conditions and creates a departure reminder so you arrive on time, every time. No more guessing when to leave. No more scrambling when traffic is worse than expected. Just persistent alerts that get you out the door at the right moment.

ESPECIALLY HELPFUL IF YOU:

  • Lose track of time between when reminders appear and meetings start
  • Miss meetings even when you set alerts
  • Get hyperfocused on tasks and forget about upcoming calls
  • Want reminders that don't disappear if you miss them
  • Struggle with "out of sight, out of mind" notifications
  • Need help with commute timing and traffic planning
  • Experience "time blindness"

FREE VERSION

  • Connect one Google or Microsoft calendar
  • Automatic alarms for all calendar events
  • Persistent, customizable notifications
  • Recurring event and Do Not Disturb controls
  • See which events have location-based travel alerts available

PAID VERSION (7-day free trial on annual plan)

  • Calendars from both Google and Microsoft
  • Supports Multiple accounts (work + personal calendars)
  • Business hours filtering
  • Time to Leave alerts with real-time traffic
  • Customizable travel modes (driving, transit, walking)
  • Departure buffer settings

OnTimer runs in the background, monitoring your calendar and creating alarms so you never have to think about it. Stop setting manual alarms every morning. Stop the anxiety about missing important meetings. Just set it once and let OnTimer handle the rest.

Perfect for remote workers, consultants, managers, students, and anyone who takes meetings seriously.

I use Claude to plan my entire schedule. 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.

My grandfather always told me that if you’re on time, you’re five minutes late. Ontimer make sure that I’m never on time but rather early and impress my meeting.
