Both are free to download. 99围棋2.0 sells 9 one-off in-app purchases and Go katago sells 10 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
99围棋2.0 holds the better App Store score, 3.6 against 3.3. Both are backed by a comparable volume of ratings — 23 and 24 respectively. Written reviews complicate that: 38% of 99围棋2.0's written reviews are positive against 65% of Go katago's, so the app with the better star average is not the one people write more warmly about.
