Verdict

The call

The clearest difference is review sentiment: Xiaoxiang BMS at 55% against PV Solar Forecast's 19%. Xiaoxiang BMS also leads on update cadence (every 4 weeks vs every 3 months). PV Solar Forecast's advantage is rating (4.0 vs 3.6) and iOS requirement (13.0 vs 16.0). On price, ratings volume, ads and in-app purchases there is nothing between them.
