### 4/5 — Finally a base calculator ... almost.

*2014-02-03, version 2.0*

This is a calculator that I have been looking for for some time one, that is, one that will do calculations in bases other than the customary base-10, specifically base-12, or dozenal.  I love using the base-12 system, but it killed me that I couldn't calculations that I would normally use a calculator without using my computer at home.  This is fantastic for simple operations (+, -, *, /) but it will become an *amazing* app once it adds other much-needed scientific calc features, such as sine, cosine, and tangent, as well as things like square roots, exponentials, etc.  Then this will become a truly powerful app.

I look forward to future updates with new features like these, and perhaps soon I can change that review from 4/5 stars to a full 5/5 stars.  Thanks a ton for the app.

### 1/5 — "Do not buy!

*2012-09-27, version 1.1*

"This app does not subtract bases correctly!"

### 5/5 — Awesome

*2011-02-16, version 1.1*

I love it.

### 5/5 — Simple and worth it

*2010-01-16, version 0*

This app is worth getting. It is simple and straightforward. Most calculators aren't clear on how to convert or deal with multiple bases and this app helps you and makes the process effortless
