ココイル is a travel and navigation app developed by electrodreaminc. It allows users to share their current location with their friends and family. Whether you want to know where your friends are for a meetup, a group outing, or during an event, this app is perfect for keeping everyone connected.

With ココイル, you can create circles and invite your friends to join. By sharing a unique ID and password generated automatically when creating a circle, you can limit the sharing of your location to only a select group of people.

You can customize your own icon by adding your name, illustration, and message. The message can be freely entered or selected from a list of preset phrases, making it easy to communicate with just a tap.

When you join a circle, you will receive push notifications whenever there are updates to your friends' messages. This ensures that you stay connected and informed even when your phone is in your pocket.

The circle leader can set a "destination" for the group, making it easy to find a meeting point or landmark. Additionally, you can draw routes from your current location to the leader's set destination for reference.

To ensure safety, the avatars of members who have not moved for a certain period of time will change color and stop animating. If you notice this, it may indicate a problem, and you can reach out to them using other means of communication.

Circles created in ココイル will automatically expire after 12 hours, so you can use the app without worrying about continuously sharing your location (extensions are also possible). You can leave a circle at any time, and once you do, your location will no longer be visible to the circle members.

Please note that using ココイル may consume a significant amount of battery due to continuous GPS usage in the background.
