Verdict
The clearest difference is price: Mole OTG at Free against Math Formulas's $0.99. Mole OTG also leads on update cadence (daily vs monthly) and iOS requirement (12.0 vs 17.6). Math Formulas's advantage is ads (none vs shown). On in-app purchases and device support there is nothing between them.
