As with most apps, there is no setting for changing orientation from portrait mode to landscape. I have a Galaxy View (18.7 inch screen) that due to its size does not have a screen rotate function. So this app is full height but with width being proportional it is like using the app on a 7" tab w/ function text very small & not easily read. I can't even imagine using this app on a smartphone. Uninstalled. UPDATE: Reinstalled. No changes to allow landscape mode. So much for improving on it.
