ElectriCalc Pro's advantage is ratings volume (368 vs 3) and device support (3 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. ElectriCalc Pro sells 2 in-app purchases, starting at $4.99 per month and Pryzmr sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
