Verdict

The call

The clearest difference is price: e at Free against HVAC Decoder's $9.99. e also leads on rating (4.8 vs 4.0) and update cadence (every 2 months vs every 3 months). HVAC Decoder's advantage is review sentiment (69% vs 50%) and chart position (#200 vs unranked). On ratings volume, ads, in-app purchases and device support there is nothing between them.
