Verdict

The call

The clearest difference is ads: 21日で学ぶ歎異抄 at none against Palace Walk's shown. 21日で学ぶ歎異抄 also leads on update cadence (every 4 days vs fortnightly). Palace Walk's advantage is device support (4 vs 2) and iOS requirement (15.6 vs 17.0). On price and in-app purchases there is nothing between them.
