GanttDroid is the GanttProject's best friend.
GanttDroid is a Project management application made for the Android platform, that enables you to manage all your projects anywhere you are.
GanttDroid is not 100% compatible with Microsoft Project files. If you need all the features of your MS Project files this app is not for you.
However, GanttDroid is completely compatible with Ganttproject (see http://www.ganttproject.biz).
If you believe that GanttProject is sufficient for you, then the combination of GanttProject on your PC and GanttDroid on your Android device will allow you to access and manage your projects on the go.
You can import MS Project files in Ganttproject, save them as Ganttproject files and, from now use them with both, Ganttproject and GanttDroid.
You can view the Gantt charts and modify any data of your projects. Any project created with Ganttproject or GanttDroid can be edited with both applications, and the result is the same in any one.
Ganttdroid is integrated with Dropbox (see http://www.dropbox.com), so if you install the Dropbox client on your PC, you can access directly all the projects you have in your Dropbox folder from anywhere you have internet access.
Other applications do not have all the capabilities of ganttdroid, or just allow you to display the projects, without the ability to edit.
This is a free version, which is only able to store the projects in the device's internal memory, so you can't share projects with a PC. Furthermore it is not integrated with Dropbox, and has advertising.
We recommend you to try the Lite version before purchase the pro, because we can't guarantee that the application will work on your device.
