# 燃渊 vs 次元钥匙

The clearest difference is review sentiment: 次元钥匙 at 100% against 燃渊's 52%. 次元钥匙 also leads on rating (5.0 vs 4.0). 燃渊's advantage is update cadence (every 10 days vs every 2 months) and ratings volume (6 vs 1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 燃渊 sells 7 one-off in-app purchases and 次元钥匙 sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

次元钥匙 holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: 燃渊 has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 52% of 燃渊's written reviews are positive against 100% of 次元钥匙's.

燃渊 ships an update every 10 days, 次元钥匙 every 2 months. The most recent releases landed on October 28, 2026 and October 24, 2026 respectively.
