Verdict
The clearest difference is ads: Cuckoo Timer at none against 柠檬自习室's shown. Cuckoo Timer also leads on update cadence (every 4 days vs every 6 weeks) and ratings volume (319 vs 18). 柠檬自习室's advantage is review sentiment (95% vs 71%) and rating (4.9 vs 4.7). On price, in-app purchases, monetization model and device support there is nothing between them.
