# Statistics Formulas vs Quiz AI

The clearest difference is update cadence: Statistics Formulas at every 3 days against Quiz AI's fortnightly. Quiz AI's advantage is chart position (#194 vs unranked). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Statistics Formulas sells 7 one-off in-app purchases and Quiz AI sells 10 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Statistics Formulas ships an update every 3 days, Quiz AI fortnightly. The most recent releases landed on November 7, 2026 and November 8, 2026 respectively.
