# iformula vs GraphMath

The clearest difference is rating: GraphMath at 5.0 against iformula's 4.0. GraphMath also leads on review sentiment (100% vs 65%) and update cadence (fortnightly vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

GraphMath holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: GraphMath has 12 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 65% of iformula's written reviews are positive against 100% of GraphMath's.

iformula ships an update every 2 months, GraphMath fortnightly. The most recent releases landed on October 13, 2026 and October 5, 2026 respectively.
