Verdict

The call

The clearest difference is price: vocalBeazz at Free against iDousyn's $4.99. vocalBeazz also leads on update cadence (every 9 days vs every 2 months) and review sentiment (54% vs 34%). iDousyn's advantage is ratings volume (161 vs 7). On rating, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

iDousyn holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: iDousyn has 161 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 34% of iDousyn's written reviews are positive against 54% of vocalBeazz's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iDousyn ships an update every 2 months, vocalBeazz every 9 days. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
