I was asked to help locate a Timeliner app for the I-Pads. After much searching, I have come to the conclusion that one, as of yet, does not exist. So I have found following links which are for RWT Timeline app and website. I am including a definition taken directly from their pages. I have highlighted important attributes. I am also including a link to a web review of the I-Pad apps.
” Timeline allows students to create a graphical representation of an event or process by displaying items sequentially along a line. Timelines can be organized by time of day, date, or event, and the tool allows users to create a label with short or long descriptive text. Adding an image for each label makes a timeline more visually appealing.
Add, drag, and rearrange items as needed. Saving capability allows students to return to their work and make revisions, and they can share their final work via e-mail.”

“This app mirrors our popular timeline web-based interactive, so users familiar with one can easily adapt to the other. In fact, the two are so similar that users can send their editable .rwt files to an email address and then open their timeline right in the online tool!”
