Mieux consommer l’électricité c’est d’abord savoir quand consommer. EcoWatt est un dispositif citoyen qui permet aux Français, entreprises, collectivités et acteurs publics de consommer l’électricité au meilleur moment. En temps réel, cette météo de l’électricité permet à chacun d’adapter sa consommation : - pour consommer de préférence quand la France peut couvrir complètement ses besoins en électricité sans émettre de gaz à effet de serre (ce sont les heures vertueuses), - à l’inverse, pour éviter le risque de coupure en décalant ou baissant notre consommation durant les heures d’alertes EcoWatt Orange ou Rouge. Des widgets, un module Apple Watch et des notifications vous attendent également pour mieux consommer pendant les heures vertueuses. Rejoignez le mouvement, vous aussi devenez un EcoW’acteur !

Verdict
The clearest difference is in-app purchases: EcoWatt at none against AirBuilding's 1. EcoWatt also leads on iOS requirement (13.0 vs 16.6). AirBuilding's advantage is update cadence (fortnightly vs every 2 months). On price, ads and device support there is nothing between them.
