OneCal: Unified Calendar

One app for all your calendars. Sync Google, Outlook & iCloud seamlessly. Share booking links, coordinate with your team & stay organized across every account you have.

ALL YOUR CALENDARS, IN ONE APP

Stop juggling between Google Calendar, Outlook, and iCloud. OneCal brings all your calendars together in one clean and organized app, so you can focus on what matters instead of keeping track of where your events live.

Over 10,000 customers trust OneCal for its reliability, simple design, and responsive support.

UNIFIED CALENDAR VIEW

See every event from every account in one place. Switch between Day, 3-Day, Week, and Month views. Turn individual calendars on or off, swipe between dates, and pull down to refresh. All-day events, overlapping meetings, and time zone labels are handled cleanly, so your schedule is always clear at a glance.

AI ASSISTANT

Ask OneCal about your schedule in plain language. Find out what is on today, when you are free tomorrow, or when a teammate has a gap. Ask it to create an event, block focus time, move a meeting, or set up a repeating event. It shows a summary before anything changes. It can also check your calendar syncs, manage your booking links, and answer questions about how OneCal works. Nothing is created, edited, or deleted without your approval.

EVENT MANAGEMENT

Create events by tapping the plus button, or hold and drag on a time slot to set a custom duration. Add locations, descriptions, reminders, attendees, and video links for Google Meet, Microsoft Teams, or Zoom. Mark events as busy or free. Set up repeating events that run daily, weekly, monthly, yearly, or on a custom pattern. Edit a single occurrence or the whole series. Reply to invitations with an optional note, and join video calls with one tap.

REMINDERS AND ATTENDEES

Set several reminders for each event, from minutes to days in advance. Add attendees by email and track their replies. See at a glance how many guests are coming, unsure, or have not answered yet.

SCHEDULING AND BOOKING LINKS

Share a scheduling link and let other people book time with you. No more emails back and forth to find a time that works. Create individual booking links for one-on-one meetings, or collective links so a group can be booked together. Set durations, add buffer time around meetings, require approval, and style your booking pages to match your brand. Manage all your bookings in the app, including upcoming, unconfirmed, past, and cancelled ones. Confirm, reject, or reschedule with a tap.

AVAILABILITY SYNC

Sync your calendars in real time to avoid double bookings. Set up one-way or two-way sync between any mix of Google Calendar, Outlook, and iCloud calendars. Choose exactly what gets copied, such as titles, descriptions, participants, locations, and meeting links. Keep sensitive details private by marking synced events as private or free. Exclude events by color, and pause or resume a sync whenever you need.

TEAM COLLABORATION

View your team members' calendars and availability side by side. See who is free, plan meetings across time zones, and keep everyone on the same page. Invite team members, manage their roles, and coordinate schedules. A great fit for distributed teams.

PERSONALIZE YOUR EXPERIENCE

Choose a light, dark, or system theme. Set your preferred hour format, first day of the week, default event duration, and time zone. Rename calendars, change their colors, or hide the ones you do not need.

PRIVACY AND SECURITY

Your data stays yours. OneCal connects through OAuth2, so we never store your passwords and never analyze your calendar data. All information is encrypted in transit and at rest on secure AWS infrastructure. We ask only for the minimum permissions required. The AI Assistant sees only what it needs to answer you, and your data is never used to train AI models.
