Very handy

I've used this app for years, it is my goto app to convert temp, length, volume, speed, you name it!
Thanks!

Units

This is one fantastic app. It can convert almost any measurement that one can think of (I.e. Do you know how many cubic inches your new 3.0 liter car engine is?) This app will figure it out for you long before you can begin to find the formula. Best of all, it's totally FREE!

Since I first wrote the above review, I still find this to be one of if not the best and most useful apps ever offered. IT'S TOTALLY FREE & it really works on most any conversion that most can think of. If you paid for another "Conversion App" then you OVERPAID! I haven't found any app that works as well or is as easy to use as this one. Do yourself a huge favor and download it right away. You will find yourself using it often. To the writers of this app I wish to say, "Many thanks for a most useful, accurate, and free app!"

Needs better Watch app

I found myself using this app less and less often as it was easier to just use Google. But I have a frequent need to convert Fahrenheit to Celsius, and it looked like the Watch app was perfect for that. Unfortunately, you need to have the watch paired with your phone to do any conversion, even one that is a fixed formula that should never need a network request of any kind. Frustrating.

Does exactly what it says it does

I use this app constantly and have never experienced any troubles. It does exactly what it says it does. I don't know if the ruler adapts to different screensize, but it's correct on my screen.

One of the best free apps iv used

It was so good I forgot I downloaded it and a year later thought it was a stock Apple application. So clean and functional.

No 3rd party keyboard support

Needs to be updated to support 3rd pay keyboards.

Don't use for shoe size conversion

I ordered men's sneakers from a European store and this app said I was a 42 for a size US size 10. It turns out I'm a 44 in Europe. I'm stuck with the return shipping costs now!

Ruler is wrong.

A very useful ap but the ruler is wrong for the iPhone 6

Clearing fields crash

Clearing fields causes the app to crash

Used to be great

I really like the functionality of this app. Unfortunately in iOS 9 on iPhone 6 Plus with a third party keyboard installed it is useless. Somehow the internal keypad winds up in the upper left corner of the screen and partially off the screen. The actual keyboard does nothing when you type. Too bad because I've used it for years.
