I have been wanting exactly this but could never find it!
Thank goodness for the free app of the week or Id have never found this!!!! I am a Samsung phone user, but love my iPad. Best of both worlds. Except they hardly co-exist, if at all. This calendar lets them sync together and I am Soooooooooooooooo happy!!!! So so so so happy. Its got a couple weird hiccups, but what app doesnt? I love this so much.
