### 5/5 — The best unit converter !!!

*2013-09-16, version 1.3*

It is the best unit converter in the app store !!! No doubt about that. I'm an engineer and use this app very often. Thanks to developer.

**Developer response:** I'm an engineer too, glad to hear you are getting good use from the app.

### 5/5 — Really Nice app.

*2013-05-31, version 1.3*

It seems like it does everything
And does it well
Thanks for making it!!

**Developer response:** Yeah, if all of life were that easy. Thanks for the motivating words.

### 5/5 — Convert Anything!

*2012-10-07, version 1.2*

This is the best app made for converting between types of data. This app has more categories than any other app I have seen and it is super fast and accurate. Get it today and you won't need anything else!

**Developer response:** Honestly, there are other unit converters with more categories...if you need to convert between Chihuahuas and Dalmatians. All kidding aside, thanks for the super kind words.

### 5/5 — FlyenDutchman

*2010-12-16, version 1.2*

Best I can find and works great!! Check out the other apps. Volume Calc and Area Calc, they are great also!! My only question is what's with name Conver'b'er? I was looking for Converter and only my perseverance found this!!

**Developer response:** Converber was named before there was an iPhone. Look for it on the Windows platform. Converber was also late to the unit converter party and not ranked very well. Thank you for the encouraging words.

### 5/5 — The best - no need to look at anything else.

*2010-08-11, version 0*

Easy to use. Great for the construction industry.

### 5/5 — Best conversion app out there

*2010-07-26, version 0*

This is a must buy app for anyone who converts anything...ever. I use it almost everyday at work and at school. It saves a lot of time, and it converts practically everything.
