Overview
Description

Cal.com is an open-source scheduling infrastructure designed for individuals and teams. It provides a robust and customizable solution for managing schedules, appointments, and meetings. With its open-source nature, Cal.com offers flexibility and scalability, making it an ideal choice for businesses and organizations of all sizes.

Structured is a day-planning app that replaces a plain to-do list with a visual timeline view, showing tasks, events, and habits laid out against the hours of the day. It imports existing calendars so meetings and personal tasks appear side by side, and lets users drag tasks into open time blocks to plan a realistic schedule rather than an endless backlog. The app adds habit tracking, smart notifications, and home screen widgets so a day's plan stays visible without opening the app, and an AI-assisted planning feature can help draft a schedule automatically. It is used by students and professionals who find a visual timeline easier to stick to than a checklist, and it syncs across iPhone, iPad, Mac, and a web version.
