# 66 Days vs Coco

66 Days and Coco both sit at 4.8 stars, but that hides the real split: 100% of Coco's written reviews are positive against 50% of 66 Days's. 66 Days's advantage is monetization model (freemium vs subscription) and ratings volume (258 vs 2). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. 66 Days sells 2 in-app purchases, starting at $15.99 per month and Coco sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Coco holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: 66 Days has 258 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 50% of 66 Days's written reviews are positive against 100% of Coco's.

66 Days ships an update every 10 days, Coco weekly. Both last shipped on October 30, 2026.
