Review: MyScript Calculator

MyScript Calculator Review

Available for: iOS, Android
Company: Vision Objects
Cost: Free
Latest Update: 12/19/2012 (iOS), 1/24/2013 (Android)


The program lets you literally write calculations with your finger or stylus. Results are calculated automatically. Up to three decimal places are shown for approximations. Expressions, which include fractions and square roots, are built dynamically. You can even insert characters or draw "scratches" to remove characters.

It has a learning curve, because the app has to recognize what you write. A suggestion is to go slow at first, and let the app recognize each character. Patience is needed. However, I now can fulfill my fantasy to write calculations and have them execute.

Order of operations are similar to graphing calculators. (Negation is low on the order of operations)

I don't think describing what this app does using words, does it justice. I definitely encourage you to download it and try it for yourself.

Both the iOS and Android version (Android as of today) have the following features:

* Arithmetic and Exponents
* Percent, and it works properly! (36 - 10% = 32.4)
* Square Root, which the surd expands to accommodate long expressions under the root
* Support for the constants π, e, and ϕ (the golden ratio)
* Logarithmic functions (log to any base, ln, e^x)
* Trigonometric functions
* Absolute value
* Parenthesis
* Ability to solve equations by use of the ? and = symbols
* Factorial
* Tweet, email, or post results on Facebook (and probably other social networks)

I am excited about the future of these type of this app.

What I like to see in future updates is:
* Ability to show answers beyond 3 decimals** (see below)
* Numerical calculus: derivatives and integrals
* Matrices and complex number support, I can see the potential

Rating: 5 stars out of 5

I'll leave you with some screenshots of the MyScript app.

** Alexander Oestert of HP Forum (HP Museum of Calculators) pointed out that in the Android version that you can have decimal settings up to 6 places. (1/27/2013)

Until next time,

  2. Here is an easy way to do any sort of conversion. In this case the problem you are facing is converting the minute portion of your time, so you want to convert the minutes to hours (expressed as a decimal). You know that anything multiplied by 1 will be itself, right? You also know that anything divided by itself is also 1 (3/3=1, -9/-9=1, etc.). You also know that 60 minutes is 1 hour. Therefore if we express 1 hr/60 min. this also would equal 1 (1 hr = 60 min, therefore this is esentially the same number divided by itself and thus equal to 1) Now take the portion that you want converted and multiply it by 1 expressed as a fraction with the units you want eliminated as the denominator (bottom number) and the units you want to convert to as the numerator (top number). In this case: 15 min/1 * (1hr/60min) Think of the units as variabalbes (x or y). I also have many suggestions about the conversion through this Conversion Calculator
