Download Sunsama Calendar – Free Team Scheduling & Collaboration Tool

Overview

Sunsama Calendar is a free, cloud‑based scheduling app designed specifically for modern work teams that need to stay coordinated across time zones, projects, and daily tasks. Unlike generic calendar tools, Sunsama blends a clean, drag‑and‑drop interface with real‑time collaboration features, allowing every team member to see who is working on what at a glance. The app shines in remote‑first environments, where visibility and quick communication are essential. Users can create shared calendars for each project, attach notes, set priorities, and even tag colleagues for instant feedback. Because Sunsama is built on a web‑first architecture, it syncs automatically across devices, ensuring that updates made on a laptop appear instantly on a mobile phone or tablet. The platform also integrates with popular productivity suites such as Google Workspace, Microsoft 365, and Slack, turning a simple calendar into a hub for project planning, daily stand‑ups, and milestone tracking. While there are many alternatives on the market, Sunsama’s smart interface, zero‑cost entry point, and focus on collaborative workflow make it a compelling option for startups, freelancers, and larger enterprises alike.

Frequently Asked Questions

Is Sunsama Calendar really free?

Yes. The free tier includes unlimited users, unlimited calendars, and all core scheduling features. Premium upgrades add AI suggestions, advanced analytics, and priority support.

Can I sync Sunsama with my existing Google Calendar?

Absolutely. In Settings → Integrations you can connect Google Calendar (as well as Outlook, Apple Calendar, and others). Events created in either system stay in sync automatically.

How does Sunsama handle time‑zone differences?

Each user sets a preferred time zone in their profile. The calendar displays all events in the viewer’s local time, while storing a single canonical time internally. This eliminates confusion for distributed teams.

Is there a mobile app, and does it support offline work?

Sunsama offers native Android and iOS apps. The apps cache recent data for quick viewing, but full editing requires an internet connection. Offline support is on the product roadmap.

What security measures protect my data?

Data is encrypted in transit (TLS 1.3) and at rest (AES‑256). Sunsama complies with GDPR, SOC 2, and offers role‑based access controls to limit who can view or edit calendars.
