Context
One home, several people, a single source of truth for the dates.
Several people share access to the same home. The need: to see clearly when it is occupied, by whom, and when it is free, so the same dates are never offered twice.

Kayo's contribution
A simple tool, usable without explanation.
Kayo designed and built the application (BUILD): a monthly calendar where each person has their own colour, the details of each booking and an overview dashboard. Access is by invitation, with a secure login.
BUILD
The application
From the calendar to the details.
The calendar: one colour per person.
The details of a booking.
The dashboard: the overview.
And on a phone.
From the chosen date to the booking details, everything fits on one screen, on computer and phone alike.
Screenshots taken with sample data: the people and bookings shown are made up.
In detail
Four choices that make the tool reliable.
- One colour per person
- The calendar reads month by month: who occupies the home, and when, shows at a glance.
- No double booking
- The application refuses overlapping dates, departure day included. The mistake simply can't happen.
- Suitable permissions
- Everyone can create a booking. Only one designated person can edit or cancel it.
- Invitation-only access
- No public accounts, no page readable without logging in, and data hosted in Europe.
