# 应化e家 vs 扳手盒

The clearest difference is in-app purchases: 应化e家 at none against 扳手盒's 1. 应化e家 also leads on iOS requirement (11.0 vs 15.0). 扳手盒's advantage is update cadence (every 9 days vs every 9 months). On price, ads and device support there is nothing between them.

Both are free to download. 扳手盒 sells 1 one-off in-app purchase. 应化e家 asks for nothing beyond the download.

应化e家 ships an update every 9 months, 扳手盒 every 9 days. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
