TimeToCall is a video call scheduling app that helps people in different time zones connect.

It addresses common challenges in cross-timezone calls, such as timezone math, back-and-forth planning, and conflicting schedules.

With features like a friend world clock, smart scheduling, and built-in video calling, TimeToCall helps users check availability, find a time that works, and stay connected.

Background

The idea for this project came from my personal experience of scheduling video calls with friends living in different countries. Because of the time zone differences, I found it really difficult to find an overlapping time to call.

Problem

After user research, I found three main problems when scheduling video calls: timezone confusion, endless back-and-forth discussions, and the inconvenience of switching between multiple apps.

Solution

To solve these problems, I designed an app that helps people in different time zones connect more easily. It includes three key features: friend world clock, smart scheduling, and built-in video call function.
