Excellent

Superb app with fast evolution and quick reaction from its creators. Linked with Ganttproject I just have what I need for my projects. Imports and exports work wonderfully well
Keep up the good work.
Perhaps a few suggestions:
tasks could be defined by end date or duration rather than just duration.
Add a zoom with finger pinching when viewing the gantt

Looking forward to the next version.
