# 优考GRE vs Elastic Constants Calculator

The clearest difference is ads: 优考GRE at none against Elastic Constants Calculator's shown. 优考GRE also leads on iOS requirement (12.0 vs 16.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
