# 零维宇宙 vs e准入

The clearest difference is in-app purchases: e准入 at none against 零维宇宙's 1. e准入 also leads on device support. On price and iOS requirement there is nothing between them.

Both are free to download. 零维宇宙 sells 1 in-app purchase, starting at $3.99 per month. e准入 asks for nothing beyond the download.
