Verdict
The clearest difference is rating: ボイボTTS at 5.0 against OshaberiAI's 3.3. ボイボTTS also leads on monetization model (free with in-app purchases vs subscription). OshaberiAI's advantage is ads (none vs shown) and review sentiment (67% vs 33%). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. OshaberiAI sells 1 in-app purchase, starting at $1.99 per month and ボイボTTS sells 1 in-app purchase, starting at $2.99 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 3.3. Both are backed by a comparable volume of ratings — 4 and 1 respectively. Written reviews complicate that: 67% of OshaberiAI's written reviews are positive against 33% of ボイボTTS's, so the app with the better star average is not the one people write more warmly about.
OshaberiAI ships an update every 10 days, ボイボTTS every 3 weeks. The most recent releases landed on November 3, 2026 and November 8, 2026 respectively.
