Know exactly when to leave.
Leaveby watches the real-time MTA feed, counts in your walk, and tells you the precise moment to head out — so you catch your bus or train without sprinting or waiting.
When to leave. When to walk. When to board.
Three moments, one screen. Leaveby guides each — no timetables, no math.
Leave
Pick a destination; Leaveby counts down to the exact minute to walk out the door.
Walk
Your walking time is baked in, so “leave now” means the pace that actually gets you there.
Board
“2 stops away → board now.” An honest heads-up, even when it’s pulling in.
Everything points forward.
Real-time bus & subway
Live departures from the MTA’s public feeds — not a static schedule.
Leave-by timing
Your walk is counted in, so “leave now” genuinely means now.
At-the-stop guidance
“2 stops away → board now” — honest, even when it’s close.

On your wrist
The countdown follows you to Apple Watch — glance and go.
Private by default
No account, no tracking, and your location never leaves your device.
On every screen you check.
Widgets on the Home Screen, a Live Activity on the Lock Screen, and a glanceable countdown on Apple Watch — Leaveby meets you wherever you look, then gets out of the way.
