# iDousyn vs Unique for iPad

The clearest difference is price: Unique for iPad at Free against iDousyn's $5.99. Unique for iPad also leads on review sentiment (63% vs 34%) and iOS requirement (17.6 vs 26.0). iDousyn's advantage is rating (4.2 vs 3.4) and ratings volume (161 vs 18). On update cadence, ads, in-app purchases and monetization model there is nothing between them.

Unique for iPad is free to download; iDousyn costs $5.99 up front. iDousyn sells 1 one-off in-app purchase and Unique for iPad sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

iDousyn holds the better App Store score, 4.2 against 3.4. That said, the two scores are not equally well evidenced: iDousyn has 161 ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 34% of iDousyn's written reviews are positive against 63% of Unique for iPad's, so the app with the better star average is not the one people write more warmly about.

iDousyn ships an update every 2 months, Unique for iPad every 5 weeks. Both last shipped on October 29, 2026.
