# Bernoulli Trial vs ReadyStudy

The clearest difference is update cadence: ReadyStudy at every 5 days against Bernoulli Trial's every 3 weeks. Bernoulli Trial's advantage is iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Bernoulli Trial sells 8 one-off in-app purchases and ReadyStudy sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Bernoulli Trial ships an update every 3 weeks, ReadyStudy every 5 days. Both last shipped on October 24, 2026.
