Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
LinkBack holds the better App Store score, 2.9 against 2.5. That said, the two scores are not equally well evidenced: LinkBack has 13 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 0% of LinkBack's written reviews are positive against 8% of SANSUI's, so the app with the better star average is not the one people write more warmly about.
LinkBack ships an update every 8 days, SANSUI every 4 days. The most recent releases landed on October 6, 2026 and October 16, 2026 respectively.
