Have a droid but I bet these are on iPhone as iPhone was earlier. I am going to mention some tools that I enjoy that help in planning observing sessions and will not be diving into this thread's 'flame' but it is both amusing and informative.
MoonPhase shows the full month with phases and is 'cute' and handy to plan ahead a few weeks.
SunMoon: This is a 'real' (valuable) app that tells me actual moonrise/set and sun rise/set that I think is appropriate for astronomy.
I use them both because MoonPhase is good for a quick glance all at once to see what the weekend will be like ahead of time and SunMoon is to be used on the day you are going out OR you can bump forward or back the days to get times.
Now back to our regularly schedule 'flame'. As of yet I have not 'drank the kool-aid' for Apple products but I recognize why many people have 'religion' in this age-old debate. In the end, ya just gotta pick and go with the one that works for you (Even if you are wrong, you will be happy
)
