When-Done

Stop doing mental math with time.

"This movie is 3 hours and 17 minutes long. If I start it now, will I be in bed by midnight?"
"My render takes 4.5 hours. Will it be ready before the client meeting?"
"This subscription expires in 45 days. What exact date is that?"

We have all faced these scenarios. Adding hours and minutes to the current time—or calculating dates weeks in the future—is surprisingly frustrating. When-Done solves this instantly.

It is a clean, beautiful utility designed to answer one specific question: If I start now, when does it finish?

Whether you are a gamer, an editor, a cook, or just trying to manage your schedule, this app visualizes the finish line for you.
