Verdict

The call

The clearest difference is rating: My Solar Panel at 4.6 against Xiaoxiang BMS's 3.6. My Solar Panel also leads on iOS requirement (13.2 vs 16.0). Xiaoxiang BMS's advantage is review sentiment (55% vs 33%) and update cadence (every 4 weeks vs every 2 months). On price, ratings volume, ads and in-app purchases there is nothing between them.
