# xFormula vs 学习打印宝

The clearest difference is review sentiment: xFormula at 85% against 学习打印宝's 20%. xFormula also leads on ratings volume (55 vs 1) and update cadence (every 3 weeks vs every 2 months). 学习打印宝's advantage is rating (5.0 vs 3.9). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. xFormula sells 4 in-app purchases, starting at $1.99 per month and 学习打印宝 sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

学习打印宝 holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: xFormula has 55 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 85% of xFormula's written reviews are positive against 20% of 学习打印宝's, so the app with the better star average is not the one people write more warmly about.

xFormula ships an update every 3 weeks, 学习打印宝 every 2 months. The most recent releases landed on September 24, 2026 and August 12, 2026 respectively.
