# Mechanical Engineer vs Iodine Code

The clearest difference is price: Mechanical Engineer at Free against Iodine Code's $4.99. Mechanical Engineer also leads on rating (4.4 vs 1.0) and update cadence (every 2 months vs every 7 months). Iodine Code's advantage is in-app purchases (none vs 3) and iOS requirement (15.0 vs 17.6). On review sentiment, ratings volume, ads and device support there is nothing between them.

Mechanical Engineer is free to download; Iodine Code costs $4.99 up front. Mechanical Engineer sells 3 in-app purchases, starting at $0.99 per month. Iodine Code asks for nothing beyond the download.
