Very fast and reliable calculator, touch screen is a big plus. The help menu is a great guide and the conversion features is very helpful. Ads can be annoying but they don't pop up offline. One thing it is missing is a button to find the 'n' th root of a number, other than that it has pretty much everything. Edit: it does have an 'n' th root! I was blind
