# 이테시스 vs 산업안전기사

The clearest difference is in-app purchases: 이테시스 at none against 산업안전기사's 1. 이테시스 also leads on iOS requirement (11.0 vs 13.0). 산업안전기사's advantage is device support. On price there is nothing between them.

Both are free to download. 산업안전기사 sells 1 one-off in-app purchase. 이테시스 asks for nothing beyond the download.
