About

Koyomi is a calendar for teams that work across time zones. An office overseas. A teammate working remotely. A colleague on a trip. Are you still working out "what time is it for them?" and "have they finished for the day?" in your head, every single time? Register each member's location and working hours once, and Koyomi puts your whole team's "now" on a single screen. ■ Today Your own day and your team's status, at a glance. See who is working right now and who has already finished. There is a space to jot down what you got done, too. ■ Events without the math Create one event and it is shown in every participant's local time. No more adding "15:00 JST = 13:00 Hanoi = 08:00 Budapest" by hand. ■ Find free time Pick the people and search. Working hours, working days, existing events and time zones are all taken into account, and you get the slots where everyone is free. Turn one into an event in a tap. ■ World Map Your members' cities and their local times, on a world map. See how far across the world your team reaches. ■ Public holidays Holidays for 43 countries and regions appear on the calendar automatically, so you never schedule over someone's national holiday. ■ Messages A thread on each event, one-to-one direct messages, and group chats. Pin the messages that matter, and send photos. Conversations stay attached to the work, so they are easy to follow later. ■ Notifications A reminder arrives before an event starts. The timing can be set per event. ■ Home screen widget Your team's local times, without opening the app. ■ Proverb of the day One proverb from somewhere in the world, every day. A small way to learn the words your teammates grew up with. ■ Japanese / English Switch the language any time in settings, so overseas members can use the same app. - Good to know - - Create a company account first, then add teammates with the invite code it gives you. - Data is kept completely separate per company. No other company can see it. - You choose how your location is shown, down to the city or not at all. No GPS is used. - Koyomi is free to use right now.
