# Quick Compute vs Speed calculation

Quick Compute and Speed calculation 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. Quick Compute sells 1 one-off in-app purchase and Speed calculation sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Quick Compute ships an update every 4 months, Speed calculation every 5 months. The most recent releases landed on July 4, 2026 and September 20, 2026 respectively.
