What Makes a Master Schedule Masterful
You’ll know who’s doing what—and when—without the daily scramble.
One place, all your plans.
Pull together calendars from Outlook, SharePoint, and Google into one clean master schedule with the Virto Calendar App. View everything side-by-side with overlays and detailed views—finally, no more tab-hopping.
Want to keep it simple? The Virto Shared Calendar lets you share a master schedule with your team or external folks—no Microsoft accounts required.

Right people, right tasks, right on time.
With the Virto Calendar App, tasks and deadlines from SharePoint lists and Microsoft Planner sit next to meetings, and room and equipment mailboxes show which resources are taken. Color-coded categories and each source's own permissions keep things crystal clear.
The Virto Shared Calendar keeps everyone on one calendar—in a browser, in Teams or on a phone—perfect for distributed teams that don’t have time for “Wait, what’s the plan?”

Make it work your way.
The Virto Calendar App supports custom views, advanced filters and drag-and-drop rescheduling, and overlays Microsoft Planner plans and SharePoint task lists, down to a Gantt view. Your master scheduling system, your rules.
Using the Virto Shared Calendar? Enjoy tags and colors, mobile access, and sharing permissions—because master schedules should be flexible, not frustrating.

Key benefits
See the big picture (and the small stuff)
View all your timelines, milestones, and room and equipment bookings in one place with a clear, easy-to-navigate master schedule. Overlaps show up side by side before they turn into double bookings.
Everyone’s on the same page
Keep your team in sync with better visibility and fewer surprises. A solid master scheduling setup makes overlaps visible early and makes sure everyone knows what they’re responsible for.
Share it like a pro
Whether it’s with your internal crew or outside partners, flexible sharing options make your master schedules easy to distribute—without the messy email chains.
See what’s taken and what’s free
With the Virto Calendar App, room and equipment mailboxes sit next to people’s calendars, so you can see which rooms and equipment are taken and which are free before you plan.
Less time managing, more time doing
Say goodbye to copying dates between calendars. The Virto Calendar App reads them from where they already live, so there is one version to keep up to date and fewer errors creep in.
You’re in control
Sensitive schedule info? No problem. Granular permissions in your master schedule mean only the right eyes see the right things—simple, secure, and stress-free.
