Calwidget is a fantastic app! I tested its commercial counterpart and found this free app is just as powerful and with as many features. It comes with a variety of widget sizes, customisable colour coding, customisable UI look and feel, and more! I use my Android for work and have a large calender on my home screen. One tap and it takes me to the calender. The app is very stable and lightweight. I’d recommend it to everyone who uses the Android for more than just fun!
