"Impressive features like carbon calculator and personalized recommendations are fantastic." 3. "Love the gamification aspect, it makes taking action on climate change fun." Cons: 1. "Limited scope for customization, wish there were more options for tracking habits." 2. "Some features are glitchy, need to re-start app frequently to fix issues." 3. "Wish there were more tangible actions to take, feels like just a carbon offsetter." Please note that these are based on the publicly available reviews on the App Store, and may not be exhaustive or entirely objective.
