# Graph vs HeatCond2D

Graph and HeatCond2D are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Graph sells 1 one-off in-app purchase and HeatCond2D sells 5 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Graph ships an update monthly, HeatCond2D every 3 weeks. The most recent releases landed on October 6, 2026 and September 17, 2026 respectively.
