# Simultaneous Equations vs Bernoulli Trial

The clearest difference is price: Bernoulli Trial at Free against Simultaneous Equations's $1.99. Bernoulli Trial also leads on update cadence (every 3 weeks vs every 36 months) and device support (3 vs 1). Simultaneous Equations's advantage is in-app purchases (none vs 8) and iOS requirement (12.0 vs 15.0). On ads there is nothing between them.

Bernoulli Trial is free to download; Simultaneous Equations costs $1.99 up front. Bernoulli Trial sells 8 one-off in-app purchases. Simultaneous Equations asks for nothing beyond the download.

Simultaneous Equations ships an update every 36 months, Bernoulli Trial every 3 weeks. The most recent releases landed on September 23, 2026 and October 2, 2026 respectively.
