I don't often buy apps above the basic level, but Business Calendar (and now Business Calendar 2) has helped me keep track of appointments so well for so long that I did. I've now had premium for almost a year & still thoroughly enjoy the added functionality & appreciate that the app is fully functional (albeit with some added time required in some cases) at the free level. Thanks for such a great app, & please make this app for iPhone too so my partner & I can use the same calendar app!
