# QQ邮箱 vs 计算器i

The clearest difference is rating: 计算器i at 4.5 against QQ邮箱's 3.6. 计算器i also leads on review sentiment (76% vs 50%) and update cadence (every 9 days vs monthly). QQ邮箱's advantage is ads (none vs shown) and ratings volume (741 vs 10). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. QQ邮箱 sells 6 in-app purchases, starting at $1.99 per month and 计算器i sells 6 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

计算器i holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: QQ邮箱 has 741 ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 50% of QQ邮箱's written reviews are positive against 76% of 计算器i's.
