Customer Reviews

Almost perfect

Except the very first conversion I wanted to check was grams to teaspoons and there's no ability to check since grams is under Mass and teaspoon is under Volume. Grams (and everything else in Mass) should be available in Volume as well.

Nice converter app

Excellent and convenient converter app. Everything is just the way it should be - no more no less. The only thing that bothers - is icon - it could be better (more simple, less objects)

Good UI but Currency update doesn't

Good UI but Currency updates doesn't work in China even updated to this newest version.

Please fix it, it is been a long time issue. Thank you!
