The annoyance
My family lives across three continents and four time zones.
Trying to schedule a FaceTime call usually meant someone suggesting a time, everyone converting it to their own time zone, correcting mistakes, and starting over.
The math wasn't hard. Doing it for four people at once was annoying enough that we kept putting calls off.
I wanted to answer one simple question:
When is everyone awake and free enough to talk?
The idea
Most time-zone tools gave me accurate clocks and dense grids. They helped me calculate time differences, but I still had to work out which times were good for everyone.
I wanted something I could understand at a glance.
So I built Meetwell.
Each person gets a 24-hour timeline showing their day visually: daytime, early or late hours, and night.
Stack the timelines and the overlap becomes clear.
Making it useful
The first version only compared time zones. Using it exposed a few missing pieces.
I added a benchmark time zone so every comparison has a clear reference point.
I added day navigation so I could plan for Saturday instead of only looking at today.
Then I added recommended windows. Meetwell scores possible times based on how comfortable they are for everyone. Daytime ranks highest. Early and late hours rank lower. The middle of someone's night isn't suggested.
Finally, I added drag-to-pick. Drag across the timeline to test a time and instantly see what that moment means for everyone else.
That interaction removed the time-zone math altogether.
The result
Now when someone asks, “Can we call this weekend?” I open Meetwell, pick the day, and see the best windows with everyone's local time next to them.
No conversion. No guessing. No back-and-forth.
More importantly, we started calling more often because finding a time stopped being work.
What’s next
Daylight saving changes happen on different dates around the world. Meetwell calculates the time correctly, but it doesn't yet explain why someone's usual time may suddenly shift by an hour.
I'd surface those transitions so users can understand the change rather than wonder whether the tool got it wrong.
A simple tool that turns four clocks into one decision.
