Verdict
The clearest difference is ads: Calculate84 Plus at none against Graphing Calculator 84's shown. Calculate84 Plus also leads on iOS requirement (13.0 vs 15). Graphing Calculator 84's advantage is review sentiment (84% vs 64%) and ratings volume (5.1K vs 306). On price, rating, update cadence and in-app purchases 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. Calculate84 Plus sells 10 in-app purchases, starting at $2.99 per month and Graphing Calculator 84 sells 4 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.5 for Calculate84 Plus against 4.6 for Graphing Calculator 84. That said, the two scores are not equally well evidenced: Graphing Calculator 84 has 5.1K ratings behind it against 306, so its average is the more settled of the two. Written reviews are what separate them: 64% of Calculate84 Plus's written reviews are positive against 84% of Graphing Calculator 84's.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
