Verdict
The clearest difference is rating: RedShelf at 4.5 against KHQ's 1.7. RedShelf also leads on monetization model (free vs free with in-app purchases) and ratings volume (7.1K vs 58). KHQ's advantage is review sentiment (19% vs 3%) and iOS requirement (11.0 vs 16.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
RedShelf holds the better App Store score, 4.5 against 1.7. That said, the two scores are not equally well evidenced: RedShelf has 7.1K ratings behind it against 58, so its average is the more settled of the two. Written reviews complicate that: 19% of KHQ's written reviews are positive against 3% of RedShelf's, so the app with the better star average is not the one people write more warmly about.
KHQ ships an update every 5 months, RedShelf every 5 weeks. The most recent releases landed on October 7, 2026 and October 16, 2026 respectively.
