You could make the core of Simple Calendar Pro for yourself: calendar. What you would give up is listed below. Whether that is worth the price is your call. At $2.99, paid once, it costs less than the weekend it would take to replace, which is the argument for keeping it. Simple Calendar Pro is open source, so there is a third way: take its code and run it yourself. - You could make: Calendar: an app builder makes this well. - You could not: A real app for Android. Something home-made would be a web page. - You could not: Hooks into the device itself: widgets. A judgement by ToolGPA from this listing, by rules that are the same for every tool.
