Verdict

The call

The clearest difference is price: Thermistor Tool at Free against Math Solver Pro's $4.99. Thermistor Tool also leads on iOS requirement (13.0 vs 16.0). Math Solver Pro's advantage is in-app purchases (none vs 1) and update cadence (every 2 months vs every 10 months). On ads and device support there is nothing between them.
