Apple’s core iOS apps are good enough for what they are intended for but there are much better apps out there that can improve your iPhone or iPad experience. A lot of them are free and the others are worth the price tag. Here I will offer a list and short review of each.
Yahoo! Weather – A gorgeous and elegant app with much more info such as hourly and five day forecast, radar map, wind & pressure, precipitation, sunrise & sundown times, and moon info all with beautiful background pics from Flickr – Free for iPhone
Calendars by Readdle – A free alternative for both the iPhone and iPad. I love that you can swipe between each month instead of hitting left or right arrow buttons. Also, instead of seeing colored dots where you have appointments you can actually read them in the month-view calendar. Much better especially when you want to quickly glance at what you have going on. – Free for iPhone and iPad.
