Verdict
The clearest difference is in-app purchases: Echo回声练习 at none against DuoPlus Cloud Phone's 5. Echo回声练习 also leads on device support (3 vs 1) and iOS requirement (13.0 vs 16.6). DuoPlus Cloud Phone's advantage is update cadence (every 2 days vs every 3 weeks). On price and ads there is nothing between them.
