Verdict

The call

The clearest difference is price: TOEFL Exam Prep at Free against FormulaBar's $0.99. TOEFL Exam Prep also leads on update cadence (every 3 days vs every 8 months) and iOS requirement (13.4 vs 15.0). FormulaBar's advantage is in-app purchases (none vs 2) and ads (none vs shown). On device support there is nothing between them.
