This is very good astronomy app for the serious amateur astronomer. The tool set is extensive and accurate.
The last update contains a bug in that it sometimes truncates the display if cold started while the iPad is in landscape mode. Until the next bug fix, the work around is to make sure that Astromist is not in memory (open the running app display on the iPad and delete Astromist if it is running). Then just make sure the iPad is in portrait mode and start Astromist. Astromist will preform normally in portrait or landscape.
