Our story
Built for one clear need
HowLongUntil started from a simple need: knowing how much time remains until a specific hour — lunch, end of shift, a meeting, midnight.
Existing tools were buried in bulky apps or cluttered with noise. We built a clean, fast countdown platform that stays out of the way and works everywhere.
Today the 24-hour engine covers every hour of the day, helping people stay organized and in control of their schedule.
