# Bernoulli Trial vs Career Ladders

Bernoulli Trial and Career Ladders 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. Bernoulli Trial sells 8 one-off in-app purchases and Career Ladders sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on October 24, 2026 and October 28, 2026 respectively.
