Timeline 3D is a great app for creating and presenting timelines on the iPad. From a list of events organized by date the app creates a 3D presentation which can then be navigated through.
To start a new timeline click on the plus (+) icon, tap Create Timeline and then give your project a name:
You can now create new events, view or edit any existing events or tap play to present your timeline:
At the top of the screen you can also tap Configure to change the theme and a few other options.
Tap the plus icon (+) on the above screen to add a new event and then simply fill in all the details (dates, notes, links) required. You can also add a picture or movie from your Camera Roll where it says Add Media:
Once you have added all the events for your project tap the play button to present your timeline. The app will first prepare your presentation:
Then present it in a 2D overview:
You can now tap any event and it will switch to a 3D view which you can scroll through taping left or right:
Timeline 3D also has multiple options to share your project. Tap the share icon to see these options:
Sharing as a PDF is probably the most useful of these options, but you can also publish to the web or export as a slideshow that can be viewed in PowerPoint.
