Ratings and reviews

Great app! The quick convert home page makes it a LOT quicker to use than the ones that make you click through multiple screens to get to a conversion. What would make this 5 stars and even worth paying a few bucks for is if you could edit the quick convert page to have your favorite units instead of a standard array of common ones. I never need options 5-9 on that page but if I could replace them with a currency calculator, inches to centimeters, etc. that would make it perfect.

very good app. the fact that its free is great ... but being unable to remove or add unit conversion options the main screen.. and theres so very many i will never use ( that i'm sure are helpful for many other people who don't use the ones that I require) I need them at the very least to NOT be on top and so very many that arent on the home screen I have to hunt for. functionality update please... other than that, its free and highly accurate so ill probably keep it.

Pretty good conversion app with most of the commonly used units on the one page. Perhaps, for Australia, a couple of things would be handier on the first page, but once you start to get the hang of navigating things, it works well.

What’s new

Removed Bulgarian lev (BGN) from the list of currencies, as it was removed from the euro foreign exchange reference rates by the European Central Bank.
