Fun Fact: The 90-Hour Flight Around the World

In 1986, the Voyager aircraft completed the first non-stop, non-refueled flight around the world in just over 90 hours. That means your 90 hour timer could time one of the most legendary achievements in aviation history. It’s a reminder of what can be accomplished when time is structured and purposeful.

Structured Time Sparks Results

By launching a 90 hour countdown timer, you’re setting intention. You’re putting a fence around distraction and giving yourself permission to focus. Just like with our meeting timer, classroom teaching timer, or exam preparation timer, defining time improves how you use it. It turns chaos into calm, and effort into progress.
