ReceptionRating · Positive reviews · Number of ratings

Smilophone holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: iDousyn has 161 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 34% of iDousyn's written reviews are positive against 0% of Smilophone'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, Smilophone every 11 months. The most recent releases landed on October 21, 2026 and October 14, 2026 respectively.
