Does not collect data so goes straight into the shortlist. Then goes to the top of the shortlist because: This one's for people who have a brain but don't want advanced maths features. It has an easy, clear & quick layout, also has the often needed brackets key (parenthesis) and standard symbols. Also has optional features which are extremely useful when you need them.

used to be ok - a bit slow to load up, but a great calculator. recently, the ads have just gone way over the top. there's always an ad on startup that I have to wait for, then search for some hidden button to remove it. also, swapping screens to look up a figure to use in a calculation results in yet another ad. it's way, way over the top. greedy app developers. I'll be uninstalling it and using a different calculator. shame, because I liked it

Excellent calculator. I only use it for basic calculations, but it does those well/accurately. Has different themes too, which is nice. 😃 I would like a way to pay to get rid of ads, since they tend to be distracting for me even though they are only a banner at the bottom of the screen. Otherwise this is a great app that I've enjoyed for almost a year so far. Thank you for your service!
