Airport Departure Board Design
A flip-clock display inspired by classic airport departure boards. Bold, clear and instantly readable — just like the real thing at Gatwick or Stansted.
100+ Destinations Worldwide
Pre-loaded with the most popular UK flight routes: New York, Dubai, Singapore, Tenerife, Malaga, Bangkok and dozens more. Add any destination with one click.
Sunrise & Sunset Times
Know exactly when the sun rises and sets at your destination. Handy for planning early morning airport transfers or evening arrivals.
Office Hours Indicator
Colour-coded status badges show at a glance whether it's office hours, early morning, evening or night-time at each destination. Never call a client at 3 AM again.
Date & Day Difference
