Verdict
The clearest difference is in-app purchases: CitizenPrep at none against U.S. Citizenship Test '26's 1. CitizenPrep also leads on ads (none vs shown) and update cadence (every 11 days vs every 2 months). U.S. Citizenship Test '26's advantage is iOS requirement (14.0 vs 16.0). On price and device support there is nothing between them.
