Verdict
The clearest difference is ratings volume: Bookshelf at 37 against Stacks's 1. Bookshelf also leads on iOS requirement (15.5 vs 17.0). Stacks's advantage is review sentiment (100% vs 88%) and update cadence (every 5 days vs every 2 weeks). On price, rating, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Bookshelf sells 6 in-app purchases, starting at $2.49 per month and Stacks sells 4 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
Stacks holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Bookshelf has 37 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 88% of Bookshelf's written reviews are positive against 100% of Stacks's.
Bookshelf ships an update every 2 weeks, Stacks every 5 days. The most recent releases landed on October 30, 2026 and November 1, 2026 respectively.
