# Graphing Calculator X84 vs IntroStat

The clearest difference is review sentiment: IntroStat at 92% against Graphing Calculator X84's 38%. IntroStat also leads on rating (4.9 vs 4.5). Graphing Calculator X84's advantage is ratings volume (50K vs 24). On price, update cadence, ads and in-app purchases there is nothing between them.
