Ratings and reviews

A neat calculator. 1. Seems like the functions library is only available with the premium content, I don't see the library icon, which is shown in "Help". 2. I use just one formula, a widget would be useful, to get right to it. 3. Some weird full page ads, i.e. Your account has been hacked, click to remove...blah blah blah the usual nonsense stuff. Then there is a minute arrow to go to the app. Not a very appropriate ad for your app.

simple but effective. However, If my phone were to need replacing, there is no backup and restore. It woukd be convenient to copy the results to clipboard. Author of app is active. No major bugs yet. New update has a little tip on how to use a built in function.

Does the job really well !! i wanted to create some quick calculators for my trading and its just the perfect tool. one tip: i wish it had like more than 1 output or formula option within 1 calculator would make things wayyy easy.
