The laws of exponents and the calculation of power of a number are no longer a problem. With 5 different modes you can calculate different formula compositions. These compositions are the most common use cases of power calculation. You only have to enter your exponent to start the calculation. Values for constants and bases can be entered too, but it is optional. The root calculation is also part of this app. If you need an overview of the laws of exponents - download this app! Decimals, fractions and negative values are supported. The solution is shown step by step. All calculations are stored in the history. The final solution can be shared. [ Contents ] - 5 different formula compositions for power calculation - exponents, bases and constants can be entered - if the base is missing, the calculation runs with the variable x or y - results are calculated and simplified - root calculation and reciprocal are taken into account - list of laws of exponents - history function to save the input - detailed solution - negative values, decimal numbers and fractions are supported - no ads! [ Usage ] - there are fields for entering values using a special keyboard - press the check mark button at the bottom right to start the calculation - values for exponents are required - if exponents are missing, the relevant field is highlighted in yellow - if other values are missing, the app will use default values - if the values are wrong, the affected field will be highlighted in red - the entries in the history can be deleted or sorted - if you select an entry in the history, it will be automatically loaded for the calculation - the whole history can be deleted by pressing a button - solutions can be shared - touching the question mark button displays information about the topic

Verdict
The clearest difference is price: Matrix Operations at Free against Advanced Power Calculator PRO's $1.99. Matrix Operations also leads on rating (4.7 vs 2.0) and update cadence (every 10 days vs monthly). Advanced Power Calculator PRO's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support and iOS requirement there is nothing between them.

Matrix Operations is free to download; Advanced Power Calculator PRO costs $1.99 up front. Matrix Operations sells 1 one-off in-app purchase. Advanced Power Calculator PRO asks for nothing beyond the download.
Matrix Operations holds the better App Store score, 4.7 against 2.0. That said, the two scores are not equally well evidenced: Matrix Operations has 19 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 75% of Matrix Operations's written reviews are positive against 100% of Advanced Power Calculator PRO's, so the app with the better star average is not the one people write more warmly about.
Matrix Operations ships an update every 10 days, Advanced Power Calculator PRO monthly. Both last shipped on November 3, 2026.
