Verdict

The call

The clearest difference is price: BOHN at Free against Thermal Engineering Calc's $2.99. BOHN also leads on update cadence (every 3 months vs every 15 months) and rating (5.0 vs 4.7). Thermal Engineering Calc's advantage is ratings volume (6 vs 1). On ads, in-app purchases and device support there is nothing between them.
