# Electrical Engineering vs Calctronics

The clearest difference is review sentiment: Electrical Engineering at 74% against Calctronics's 14%. Electrical Engineering also leads on rating (4.9 vs 4.0). Calctronics's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (13.0 vs 15.5). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Electrical Engineering sells 7 in-app purchases, starting at $3.99 per month and Calctronics sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
