Pros & Cons:
- Novel app for navigating PDF docs with tilt gestures!
- Scroll pages without touching the screen!
- Difficult to get working consistently.
- More novel than useful.
RotoView PDF Reader allows you to tilt your device up or down to scroll the page that direction in addition of side to side directions. To use it you open a PDF file. Initially when the average user opens the file browser, it looks so overwhelming but there is a feature to filter all PDF documents located on your device- which in my opinion should be shown first and the file browser offered as an advanced option. :-/
Once the file is opened via the app you must activate it by shaking the device with an up and down shake. Then hold anywhere on the side borders, tilting in the direction you would like the page to scroll. For example tilt up to scroll up, tilt right to scroll right. There are two main operations for scrolling which involves touching the screen or not.
For touch control, you must tap and hold the edge of the screen to invoke a small box. Then you can scroll your device in any direction while still holding the screen. For touch-less control, the small control box will appear while scrolling. You can tap to stop scrolling and again to restart scrolling. There is a feature to allow scrolling from page to page by double tilting the device (this must be enabled in the Settings menu- disabled by default). Note: in my evaluation I had difficulty getting these operations to consistently work.
There are a few other features to annotate the document including handwriting on the doc, drawing lines, selection boxes, etc. These features can be saved by unlocking the full version of the app. There is a day/night reading mode, search tool and option to group all pages into one long column for easier scrolling. There are other minor ancillary settings you can toggle such as the shake sensitivity, scroll controller and more.
