Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Legacy View holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Legacy View has 4.4K ratings behind it against 599, so its average is the more settled of the two. Written reviews complicate that: 45% of Legacy View's written reviews are positive against 54% of LARQ's, so the app with the better star average is not the one people write more warmly about.
Legacy View ships an update every 3 weeks, LARQ monthly. The most recent releases landed on September 23, 2026 and September 22, 2026 respectively.
