On price, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

iDousyn Lite holds the better App Store score, 4.4 against 4.2. That said, the two scores are not equally well evidenced: iDousyn Lite has 697 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 36% of iDousyn Lite's written reviews are positive against 80% of Refader's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iDousyn Lite ships an update every 3 months, Refader every 2 days. The most recent releases landed on October 12, 2026 and September 29, 2026 respectively.
