# 二酉 vs Tesseract

二酉 and Tesseract both sit at 4.5 stars, but that hides the real split: 78% of Tesseract's written reviews are positive against 43% of 二酉's. Tesseract also leads on ratings volume (110 vs 6). 二酉's advantage is iOS requirement (16.4 vs 26.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. 二酉 sells 8 in-app purchases, starting at $0.99 per month and Tesseract sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
