Turn your Google calendar into a Gantt chart

Your benefits

Gain insights

Viewing your Google Calendar as a Gantt chart gives you a much better overview because events are grouped together by topic. Now you can make scheduling decisions faster and find event dependencies easier. With a quick glance you can determine resource availability to prevent overbooking and see what is happening at each stage of your project.

Easy to use

Simply move events around with drag&drop. Create new ones. Rename them. Color them. Everything directly inside GANTTplanner! And the best is, that all changes are automatically synced with your Google calendar.

Put things in perspective

Different zoom levels allow you to see the big picture or everything in detail. With the filter functionality, you can hide unwanted events to only see what you really need.

Be on schedule

On each calendar event, you can set a work progress. See immediately when the work has been finished or how long it will take to do so.

Collaborate. Print. Export

Collaborate with your team and clients in real time by using the online sharing functionality. If needed you can export a PDF or image of your Gantt chart too. Print or send your results by email.
