# Circle O vs 動康評

The clearest difference is in-app purchases: Circle O at none against 動康評's 1. Circle O also leads on iOS requirement (12.0 vs 17). 動康評's advantage is device support. On price there is nothing between them.

Both are free to download. 動康評 sells 1 in-app purchase, starting at $24.99 per month. Circle O asks for nothing beyond the download.
