Both are free to download. ボイボTTS sells 1 in-app purchase, starting at $2.99 per month and ずんだボイス2 sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
ボイボTTS holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: ずんだボイス2 has 13 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 33% of ボイボTTS's written reviews are positive against 73% of ずんだボイス2's, so the app with the better star average is not the one people write more warmly about.
ボイボTTS ships an update every 3 weeks, ずんだボイス2 every 2 weeks. The most recent releases landed on September 10, 2026 and September 13, 2026 respectively.
