LeaveBy

Stop doing the mental math every morning. LeaveBy works backward from your arrival time — accounting for your travel time, your chosen transport mode, and whatever buffer you need — and tells you the exact minute to walk out the door. Not "soon." Not "around 8." The precise moment, live on your screen.

WATCH THE CLOCK FLIP TO CRITICAL

Open LeaveBy and a live clock fills the top of the screen, ticking every second. Below it sits your departure hero card: a circular countdown dial that pulses green when you have time to spare, shifts to amber as the window narrows, and blazes red when you must leave right now. No digging through notifications. No recalculating in your head. One glance tells you everything.

KEY FEATURES

• Real-time departure countdown that recalculates continuously as seconds tick by
• Color-coded urgency states — Safe (green), Warning (amber), and Critical (red) — so status is instant at a glance
• Transport mode selector: Drive, Transit, Walk, or Bike — each changes the travel time calculation automatically
• Configurable buffer time (5 m, 10 m, 15 m, 30 m, or custom) so you always have breathing room before you leave
• Repeat Daily toggle — activate it once and your regular commute resets itself every morning automatically
• Multiple active countdowns at once — track your morning commute, a midday appointment, and an airport run simultaneously
• Clear trip card list showing LEAVE BY time, transport mode, ARRIVE BY target, destination, and time remaining
• Hero countdown always shows your most urgent departure so you never miss what matters most
• Large, readable clock display with day-of-week label for quick temporal orientation
• Active trip count summary so you always know how many departures are in motion
• Add Trip dialog with destination address, arrival hour/minute sliders, travel time input, and one-tap transport chip selection
• Minimal dark-themed UI designed for rapid morning glances — no clutter, no unnecessary taps

HOW IT WORKS

Tap the "+ New Trip" button and fill in four things: a trip title, a destination address, your target arrival time using the hour and minute sliders, and your travel time in minutes. Select a transport mode and choose a buffer. Tap Save Trip and your countdown starts instantly. The hero card promotes your soonest departure to the top and counts down live. When departure time arrives, the card turns red and the countdown urgency peaks. Need the trip tomorrow? Enable Repeat Daily and it resets automatically at midnight.

PERFECT FOR

Daily commuters who need to leave within a tight window every morning • Drivers and transit riders juggling multiple appointments in a single day • Anyone who has ever arrived late because they misjudged travel time • Families coordinating school drop-offs, gym sessions, and work arrivals from one screen • Frequent travelers managing airport departures with strict check-in deadlines • Professionals with back-to-back offsite meetings who cannot afford to be even five minutes behind.

PRIVACY & TRUST

LeaveBy stores all your trips locally on your device. No account is required, no location data is transmitted, and no trip information is sent to any server. Your schedule stays entirely private. Add, edit, or delete any trip at any time, and the app works fully offline — your countdown keeps ticking whether or not you have a connection.
