Verdict
The clearest difference is rating: SMA Energy at 3.7 against EMA Manager's 2.9. SMA Energy also leads on ratings volume (1.4K vs 16) and review sentiment (29% vs 16%). EMA Manager's advantage is monetization model (free vs free with in-app purchases) and update cadence (every 3 weeks vs every 2 months). On price, ads, in-app purchases and device support there is nothing between them.
