An illustration, not a live calendar. The marked band is 08:00–22:00 in each city. In the app, you set the hours that suit each person.
Keep people in mind,
wherever they are.
Find your overlap.
Choose the people, date, and call length. Compare everyone’s day on one timeline and explore suggested times with the trade-offs explained.
Make the plan.
Pick a moment, share it, or open a calendar event draft. Review the details before saving. Nothing gets booked on someone else’s behalf.
Your circle.
On your device.
No account to create. No ads to work around. The people, cities, and hours you enter are stored locally, and planning works offline.
