# 车床圈 vs 制选

The clearest difference is in-app purchases: 车床圈 at none against 制选's 2. 车床圈 also leads on ads (none vs shown). 制选's advantage is update cadence (fortnightly vs every 2 months). On price, device support and iOS requirement there is nothing between them.

Both are free to download. 制选 sells 2 one-off in-app purchases. 车床圈 asks for nothing beyond the download.

车床圈 ships an update every 2 months, 制选 fortnightly. Both last shipped on May 14, 2026.
