Verdict

The call

The clearest difference is ads: Ecotricity App at none against Three's shown. Ecotricity App also leads on monetization model (free vs free with in-app purchases). Three's advantage is update cadence (every 2 weeks vs every 19 months) and iOS requirement (15.0 vs 17.0). On price, review sentiment, in-app purchases and device support there is nothing between them.
