Never miss your
departure.
Your calendar tells you when. Your maps tell you how long. Leave On Time tells you the exact moment to walk out the door — even when the app is closed.
One email when the app ships. No spam. No tracking.
Three steps. Then it just works.
Connect your calendar
iCloud, Google, Outlook — anything synced to your phone. One tap. Read-only.
Save where you leave from
Home, Work, Client X. We use these as the starting point for every event.
Get the alert. Walk out.
Push fires the moment you need to leave. Email backup. Even when the app is closed.
Built for people who hate being late.
Calendar-driven
If it's on your calendar, it's in Leave On Time. No re-entering events.
Traffic-aware
Live Google Maps drive times, not "20 minutes on a Tuesday."
Push + email
Local push fires even if the app is closed. Email backup if your phone's silenced.
Buffer your way
Want to arrive 5 minutes early? 10? Set it once.
Multiple origins
Home, work, a client site, the kids' school. We pick the right one per event.
Privacy-first
No ad tracking. No selling your calendar. Your events stay on your phone.
Your calendar doesn't
leave your phone.
We only send a destination to Google when it's time to compute a drive time. No ad SDKs. No data brokers. No selling. Ever.
Read the full privacy policy →Questions, answered.
What calendars are supported?
Anything synced to your phone — iCloud, Google, Outlook, Exchange, subscribed iCal feeds. If iOS Calendar shows it, we read it. No separate OAuth.
Does it work offline?
Reminders that were already scheduled will fire offline (they're on your device). New drive-time calculations need an internet connection.
What if my calendar event has a vague location like "the office"?
We silently skip leave-by for those — we only run drive-time on locations that geocode to a real address.
Is it free?
v1 is free. A Pro tier with extras may come later; the core leave-by feature will stay free.
Android?
iOS first. Android on the roadmap.
Do you sell my data?
No. Read the privacy policy — short, plain English.
