It’s decent

It’s simple calculator in keyboard. Simple design and it’s free and i don’t know what subscription includes

★★★★★Cangath9/9/2020
Simple and useful

I was just looking for a keyboard with primarily numbers for excel when I stumbled on this. Very fast and light weight. Great math notes on OneNote. A perentheses button would be a great update.

★★☆☆☆Dnheller9/1/2020
Good idea, poor design

Good idea, poor design. Developer put text fields in keys, instead of designing proper key labels, so underline shows up under each text label as if it’s link like HTML, which is not needed and only clutters up the design. Even the operator keys are underlined which makes a plus sign + look like a ± plus-minus sign.
