# Mechanical Engg. Calculator vs Mechanical Engineering Toolkit

The clearest difference is rating: Mechanical Engineering Toolkit at 4.8 against Mechanical Engg. Calculator's 3.7. Mechanical Engineering Toolkit also leads on review sentiment (57% vs 25%) and update cadence (every 8 days vs every 21 months). Mechanical Engg. Calculator's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Mechanical Engineering Toolkit sells 1 one-off in-app purchase. Mechanical Engg. Calculator asks for nothing beyond the download.

Mechanical Engineering Toolkit holds the better App Store score, 4.8 against 3.7.
