Inflexible and inaccurate.
On my iPad this app displays in landscape view. This is most annoying when using the iPad in portrait mode. It doesn;t swivel and there are no options!
However, the most disappoint aspect is an apparent error. Initially, I set the time for Alberta, CA. That was fine. Later when I learned how to add individual cities, I added my home town. That worked fine, except that the two displayed times were an hour apart! I am sure it has something to do with Daylight savings time, but at this point I was so annoyed I just deleted it and purchased The World Clock by Andrei Kalev.
