# DataAnalysis vs LiquidText

The clearest difference is rating: LiquidText at 4.6 against DataAnalysis's 4.1. LiquidText also leads on ratings volume (6.4K vs 106) and update cadence (every 2 weeks vs every 2 months). DataAnalysis's advantage is in-app purchases (none vs 13) and review sentiment (64% vs 50%). On price and ads there is nothing between them.

Both are free to download. LiquidText sells 13 in-app purchases, starting at $5.49 per month. DataAnalysis asks for nothing beyond the download.

LiquidText holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: LiquidText has 6.4K ratings behind it against 106, so its average is the more settled of the two. Written reviews complicate that: 64% of DataAnalysis's written reviews are positive against 50% of LiquidText's, so the app with the better star average is not the one people write more warmly about.

DataAnalysis ships an update every 2 months, LiquidText every 2 weeks. The most recent releases landed on September 22, 2026 and October 6, 2026 respectively.
