# Job Info vs 산업안전기사

The clearest difference is in-app purchases: Job Info at none against 산업안전기사's 1. Job Info also leads on ads (none vs shown) and iOS requirement (6.1 vs 13.0). 산업안전기사's advantage is update cadence (every 8 days vs monthly). On price and device support there is nothing between them.

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

Job Info ships an update monthly, 산업안전기사 every 8 days. The most recent releases landed on October 9, 2026 and October 10, 2026 respectively.
