# 아차차 vs Spin & focus

The clearest difference is in-app purchases: 아차차 at none against Spin & focus's 1. 아차차 also leads on iOS requirement (14.0 vs 16.2). Spin & focus's advantage is ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Spin & focus sells 1 one-off in-app purchase. 아차차 asks for nothing beyond the download.
