IntroductionBelow you find the results of a detailed systematic review of advanced calculator apps for Android, available here.
Also included are high-quality “basic” scientific calculator apps with features like scientific constants, units, and base-n calculation. Further, advanced “learning calculators” are included, but only their ability to solve mathematical problems is evaluated, not their pedagogical value.
This review should be helpful to anyone who wants to do more complicated calculations on Android devices.
It is probably the first comprehensive review of Android calculator apps. While there are many “reviews” of such apps on the web, those lack
- systematic search for available apps,
- thorough tests of the apps,
- comparison of features,
- comparison of data from Google Play.
While I am myself not a mathematician, I have studied mathematical physics and computer science (PhD), and have developed complex Android apps (an advanced 3D modeling app, and App Finder, a sophisticated search engine for apps on Google Play, which I have used for this review).
If you find anything wrong or incomprehensible, please let me know!
Also, any suggestions for improvements, and for the inclusion of further apps are welcome.
Summary and RecommendationsSince the introduction of Android in 2008, independent programmers from around the world, as well as small and large companies, have developed hundreds of calculator apps (there are currently at least 430 apps with the phrase scientific calculator or graphing calculator in title or summary on Google Play, see below).
There is currently no single app with as comprehensive, reliable, and convenient calculation functionality as that of the best hardware calculators (like the TI-89, TI-Nspire, or Casio fx-CG500 / ClassPad).
However, for many purposes there are perfectly suitable apps, which are sometimes even preferable if one has a hardware calculator at hand (e.g., for graphing).
