Verdict
The clearest difference is in-app purchases: Zotero at none against LiquidText's 13. Zotero also leads on review sentiment (78% vs 50%). LiquidText's advantage is ratings volume (6.4K vs 425). On price, rating, update cadence and ads 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. LiquidText sells 13 in-app purchases, starting at $5.49 per month. Zotero asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 4.6 for LiquidText against 4.6 for Zotero. That said, the two scores are not equally well evidenced: LiquidText has 6.4K ratings behind it against 425, so its average is the more settled of the two. Written reviews are what separate them: 50% of LiquidText's written reviews are positive against 78% of Zotero's.
Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on September 25, 2026 and September 24, 2026 respectively.
