Calculator and measurement converter; consider pro version.
A Lot or a Little?
What you will—and won't—find in this app.
Calculator performs complicated math equations, and a "tape" lists recently performed calculations and their answers. App also makes it easy to convert measurements within various categories such as speed, temperature, time, mass, area, etc. When used purely as a utility, learning is more limited than when used in conjunction with direct instruction.
Ease of Play
Colorful and organized, numbers and functions easy to find. It's simple to convert from one unit to another.
Products & Purchases
In-app purchases available without parent gate.

What’s It About?
CALCBOT 2 is a calculator app that performs basic and scientific math functions. In the free version, up to 10 calculations can be saved on the "tape" history, which is a great reference to help those who like to see which functions they have just completed. The converter, which is hard to find at first, is accessed by swiping to the right on the black answer bar of the calculator. In the converter tool, the categories include currency, data size, fuel, length, mass, speed, temperature, time, volume, work, and area. Users can easily scroll through the lists to change from one unit of measurement to another. For example, when selecting mass, they can choose one pound in the middle column and see that it is 16 ounces in the far column. In the free version, users will need to copy the value into the calculator and then perform the equation, if they are using a value other than one. This could offer more educational value for those learning to understand conversions. Users can copy information, save to files including PDFs, email, message, or post on Facebook. In the upgraded pro version, users can input any value into the calculator and then convert it. For $0.99, additional in-app purchases also include the option for customizable background themes. The app also supports various languages including English, Arabic, German, Japanese, Russian, and Simplified Chinese.
Is It Any Good?
In general, a calculator is a great tool to help kids with new concepts, especially as a way to check their work and build confidence -- but it's best used with supervision and with all of the features. Colorful, organized buttons make using the calculator in Calcbot 2 simple. Since conversions from one unit of measurement to another can be challenging to remember, it might be worth it to pay for the pro version since it offers easier access to conversions with varying numbers. While this is a great strategy for those who just need to know the answer, younger kids will need to learn the basics first. On the calculator, having a way to see a favorite or frequently used calculation is an excellent strategy for users who have difficult remembering which numbers they input into the calculator. For kids with dyscalculia, a disorder that impacts their ability to learn new math concepts, the app can be used as a learning tool to build confidence in solving problems and in measurement conversions. As with any app that can provide answers, parents will want to monitor use so that kids aren't using it as a shortcut and bypassing steps in between.

Did we miss something on diversity?
Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.
