Orifice Size is calculated from given flowrate and pressure drop, Flowrate is calculated from given size and pressure drop and Pressure Drop requires orifice size and flowrate. Different taps can be selected: Flange Taps and Pipe Taps. Fluids include gases: Natural Gas (Specific Gravity must be provided), Air and Nitrogen, or liquids: Crude Oil, Water, Methanol, Mono-ethylene Glycol, Diethylene Glycol and Triethylene Glycol. In addition, selecting orifice material will adjust the sizing parameter of the orifice depending on temperature. Customary or SI-units.

Verdict
The clearest difference is price: HeatCond2D at Free against AGA's $0.99. HeatCond2D also leads on update cadence (every 3 weeks vs every 15 months). AGA's advantage is in-app purchases (none vs 5) and chart position (#191 vs unranked). On ads and device support there is nothing between them.
