Customer Reviews

Simple and so useful.

We are building a house in a country that uses the metric system. (ie any place except the US). Such a useful app as we are working with our architects. The currency converter is also a bonus. I paid the $2 because you can hit the ads on the bottom very easily and it can be annoying. If this is an important tool for you, pay for it. This developer deserves it.

Keeps last currency rate until update

If I know my budget depends on 25 miles per gallon I really get lost if gas is sold by the liter. I have never seen this conversion before and I love it. If you know your planned MPG you can check your expenses with this conversion to liters spent per kilometer. Use the currency conversion to update your travel budget.

Handy tool...

I flew overseas last week and had the chance to use this application. It saved me several times when making money exchange transactions. It also worked well when taking measurements from meters to feet. There is the need for a swap key for back and forth unit conversion.
