# Quick Graph vs 3D Data Plot

The clearest difference is review sentiment: Quick Graph at 94% against 3D Data Plot's 0%. Quick Graph also leads on update cadence (every 5 months vs every 17 months). 3D Data Plot's advantage is device support (4 vs 2) and iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Quick Graph sells 2 one-off in-app purchases and 3D Data Plot sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Quick Graph ships an update every 5 months, 3D Data Plot every 17 months. The most recent releases landed on October 31, 2026 and November 3, 2026 respectively.
