About this app

Colision is the shared calendar that prevents meeting conflicts when the same people belong to multiple groups.

Town council and its committees, associations, clubs, committees… As soon as several subgroups start scheduling independently, calendar clashes become the norm:
one meeting falls directly on another, and the most committed members have to choose, apologize, or reschedule everything.

Colision solves this: when you create a meeting, the app immediately detects people already scheduled elsewhere at the same time—before confirming it.

SIMPLE, LIKE A TRICOUNT

• No account creation required.

• One person creates the project and receives a code to share.

• Others enter the code, choose their name from the list, and select their committees.

• Getting started in under a minute.

WHAT YOU CAN DO

• Create a project and its committees (groups).

• Add members — a first name is all it takes.

• Schedule a meeting for one or more committees.

• Get alerted to scheduling conflicts before confirming.

• Receive a notification when a meeting concerns you or a conflict affects you.

• View your personal calendar, grouped across all your committees.
WHO IS IT FOR? Designed for municipal elected officials and their committees, Colision is suitable for any group where the same people move between several subgroups: associations, sports clubs, works councils, volunteer teams.

Free. No ads. No account required.
