1. OneCal

Sync your calendars with OneCal

OneCal solves a problem that many founders, managers, consultants and freelancers face: calendar conflicts.

By natively syncing bookings through Google and Microsoft Outlook, OneCal effectively prevents conflicts within each calendar. 

Moreover, you can integrate work calendars into a personal one, providing a unified platform for your tasks. Once you sync your calendars, you can decide how your events will appear, so you’ll always have maximum privacy. 

Whether you run a small business or work in a busy team, OneCal provides user-friendly tools to boost productivity and collaboration.

Important Details

Great for: Founders, freelancers, consultants, and teams.

Price: Starting from $5/user/month

Ease of use: 9.7 out of 10

Reviews: 4.9 out of 5 in G2

Free Trial: 14 days

Key Features

Calendar sync. After connecting several Google or Outlook Calendars, you can synchronize them instantly. In calendaring terms, synchronizing Google and Outlook Calendars means cloning events from one calendar to another in real-time. This way, all your calendars have the same events, and your availability is streamlined, leaving no room for team members to book a meeting when you're busy.

Unlimited booking links. Booking links allow you to manage appointments and meetings and close deals easily. Furthermore, you can copy specific time slots and share them via email, text or other media. The Booking Links feature offered by OneCal is similar to the Calendly scheduling links, allowing you to share a link and get booked.

OneCal Booking Link

Calendar view. The Calendar View feature helps tremendously when you use multiple calendars, be it Google Calendar or Outlook. It's quite annoying when you have to open Outlook and Google Calendar to get the hang of what meetings you need to join for the day. With OneCal Calendar View, all meetings are in one Calendar, helping you clearly see your schedule, quickly join meetings, and view important details.

Intuitive UI and UX. The app is quite intuitive and easy to use. You can set up your account, calendar syncs, and booking links in minutes.

Email notifications. You will receive a message whenever someone wants to plan a meeting with you, change the schedule, or cancel the meeting.

Real-time updates. Unlike manually syncing Outlook and Google Calendars, OneCal automatically keeps the calendars in sync. If an event is updated in the original calendar, OneCal will update all affected calendars.

Calendar time blocking. OneCal helps you block time across all your calendars. OneCal does an excellent job of automatically blocking time across all your calendars, prioritizing your privacy. You can time block by hiding or showing all meeting details.
