# Accelerate vs Scale Wizard

Accelerate and Scale Wizard 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. Accelerate sells 1 one-off in-app purchase and Scale Wizard sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Accelerate ships an update every 11 days, Scale Wizard weekly. Both last shipped on October 24, 2026.
