Verdict
The clearest difference is price: Cerebrux at Free against Parallel Text's $1.99. Cerebrux also leads on update cadence (every 2 weeks vs every 2 months). Parallel Text's advantage is in-app purchases (none vs 1) and iOS requirement (15.0 vs 18.0). On ads and device support there is nothing between them.
