When you need to reach someone overseas, it's easy to lose track of what time it is on their end. Zone Slider Time settles that with a single slide.
Pick two cities and slide the time, and both clocks move together. Color bands show their morning, work hours, evening, and night, and a label tells you plainly whether it looks like a good time to reach them.
A world clock tells you what time it is now. Zone Slider Time helps you find a time that works for both sides.
If now is a bad time, tap "Next good time" to jump to the next moment you are both in work hours. When you find a time that works, copy it or share it as text, ready to paste into a chat.
Save the pairs you use often, like a client in London or family in Sydney, and switch with one tap. Add the widget and the answer is on your Home Screen or Lock Screen before you even open the app.
WHEN TO USE IT
- Is it too late to call London from Japan right now?
- What time is a 10:00 Tokyo meeting in New York?
- When does an overseas live stream start in my local time?
- Will a call land during their workday, or in the middle of the night?
