# CoreAI vs Sphere

CoreAI and Sphere 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. CoreAI sells 7 in-app purchases, starting at $20.00 per month and Sphere sells 2 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

CoreAI ships an update fortnightly, Sphere every 3 weeks. Both last shipped on October 25, 2026.
