# Cotton Tree vs 30일

The clearest difference is ads: 30일 at none against Cotton Tree's shown. 30일 also leads on monetization model (free vs free with in-app purchases) and rating (4.4 vs 4.2). Cotton Tree's advantage is update cadence (every 9 days vs every 6 weeks). On price, review sentiment, ratings volume and in-app purchases there is nothing between them.

30일 holds the better App Store score, 4.4 against 4.2. Both are backed by a comparable volume of ratings — 6 and 7 respectively. Written reviews point the same way: 64% of Cotton Tree's written reviews are positive against 70% of 30일's.
