# Cerebro vs Sparko

The clearest difference is update cadence: Sparko at every 4 days against Cerebro's every 3 weeks. Sparko also leads on iOS requirement (15.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Cerebro sells 2 in-app purchases, starting at $9.99 per month and Sparko sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Cerebro ships an update every 3 weeks, Sparko every 4 days. Both last shipped on October 25, 2026.
