# 산재법OX vs 일반기계기사

The clearest difference is ads: 산재법OX at none against 일반기계기사's shown. 일반기계기사's advantage is iOS requirement (12.0 vs 15.0). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. 산재법OX sells 2 in-app purchases, starting at $2.99 per month and 일반기계기사 sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
