# SpeakColors vs Inference Ace

The clearest difference is rating: Inference Ace at 3.6 against SpeakColors's 2.5. Inference Ace also leads on review sentiment (89% vs 67%) and update cadence (every 7 months vs every 16 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. SpeakColors sells 1 one-off in-app purchase and Inference Ace sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
