OnTimer - Never be late

Never be late again. Connect Google, Microsoft and Apple Calendars once. OnTimer automatically keeps you on time. Persistent alarms and Time to Leave alerts do the rest.

You glance at your calendar reminder, think "I'll join in 5 minutes," then suddenly realize the meeting started 20 minutes ago. OnTimer automatically keeps you on time. Connect your Google, Microsoft, or Apple Calendar once, and OnTimer does the rest.

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.

Use OnTimer for:

• Meetings and calls
• Appointments
• Recurring events
• Work and personal calendars
• Events with locations
• Moments when being late costs time, trust, or causes stress

APPLE CALENDAR, GOOGLE CALENDAR, AND MICROSOFT CALENDAR

• OnTimer now supports Apple Calendar, along with Google Calendar and Microsoft Calendar.
• Connect one calendar for free, or upgrade to connect multiple calendars across work and personal life.

TIME TO LEAVE ALERTS For events with locations, OnTimer helps you know exactly when to leave. Choose your preferred travel mode, add a departure buffer, and let OnTimer monitor traffic so you head out at the right time.

• No more guessing when to leave.
• No more scrambling when traffic is worse than expected.
• Just reliable alerts that help you arrive on time.

ESPECIALLY HELPFUL IF YOU:

• See calendar reminders and still leave late

• Get focused and lose the final few minutes before a call
• Need alarms that keep reminding you until you take action
• Use more than one calendar
• Need help knowing when to join, leave, or switch tasks
• Experience time blindness or notification overload
