    Many useful features; tip, sales, percentage, e.g. in one app. All easy to use, just plug values in & applet does the rest. Now if u want a calc to do just basic arithmetic, this would be one would be an overkill.

    It's great. I keep finding uses for it every day.

    Great product, meets all my every days calculator needs. Just wish the mortgage calculator would have a field to add HOA numbers. Where I live, most communities have a home owner association fee which I have to take into consideration when calculating monthly mortgages
