# 变声器 vs BF

The clearest difference is review sentiment: BF at 86% against 变声器's 28%. 变声器's advantage is rating (4.6 vs 3.8) and ratings volume (101 vs 29). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. 变声器 sells 3 in-app purchases, starting at $1.99 per 7 days and BF sells 11 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

变声器 holds the better App Store score, 4.6 against 3.8. Both are backed by a comparable volume of ratings — 101 and 29 respectively. Written reviews complicate that: 28% of 变声器's written reviews are positive against 86% of BF's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on September 26, 2026 and September 21, 2026 respectively.
