The clearest difference is rating: GridRewards at 4.6 against ClimateResponse's 1.0. GridRewards also leads on ratings volume (977 vs 1) and update cadence (every 3 weeks vs every 2 months). ClimateResponse's advantage is ads (none vs shown) and monetization model (ad-supported vs free with in-app purchases).

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
