# Tunebook vs iDousyn

Tunebook also leads on review sentiment (75% vs 34%) and in-app purchases (none vs 1). iDousyn's advantage is rating (4.2 vs 3.0) and ratings volume (161 vs 6). On update cadence, ads and device support there is nothing between them.

Tunebook is free to download; iDousyn costs $6.99 up front. iDousyn sells 1 one-off in-app purchase. Tunebook asks for nothing beyond the download.

iDousyn holds the better App Store score, 4.2 against 3.0. That said, the two scores are not equally well evidenced: iDousyn has 161 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 75% of Tunebook's written reviews are positive against 34% of iDousyn'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 every 2 months. The most recent releases landed on October 15, 2026 and October 23, 2026 respectively.
