Verdict
The clearest difference is review sentiment: ずんだボイス2 at 74% against SeshatVoice's 0%. ずんだボイス2 also leads on update cadence (every 2 weeks vs every 4 months) and ratings volume (14 vs 2). SeshatVoice's advantage is ads (none vs shown) and rating (5.0 vs 4.7). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. SeshatVoice sells 1 one-off in-app purchase 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.
SeshatVoice holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: ずんだボイス2 has 14 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 0% of SeshatVoice's written reviews are positive against 74% 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.
SeshatVoice ships an update every 4 months, ずんだボイス2 every 2 weeks. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
