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"
