Ive had this about a week now, and each day i am more impressed with how well it meets my needs. Now I hardly ever need to look at the native iPhone calendar or another to-do app. Like so many of you I had tried other calendars without finding exactly what i needed: 1) the calendar and task list on a single page, and 2) the ability to sync with either Google or the iPhone calendar OR BOTH . This was crucial because i have an Exchange calandar for work that Google cant read, but everything else is on Google Calendar. When you are syncing with both at the same time you turn on or off exactly which calendars you want from either platform. But its the little touches that make this app so wonderful - the ability to swipe from page to page with your thumb, the use of tap, double tap, or hold to quickly add or change an entry, the ability to customize the look, feel and usability. The only thing I dont like is that when you have calendar entries starting at the same time theyre stacked on top of each other - thats confusing, as opposed to side by side, as on the apple calendar.
