Verdict
The clearest difference is ads: Mello at none against EcoGPT's shown. Mello also leads on review sentiment (97% vs 77%). EcoGPT's advantage is ratings volume (8.7K vs 111) and chart position (#142 vs unranked). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. EcoGPT sells 18 in-app purchases, starting at $5.99 per month and Mello sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.8 for EcoGPT against 4.9 for Mello. That said, the two scores are not equally well evidenced: EcoGPT has 8.7K ratings behind it against 111, so its average is the more settled of the two. Written reviews are what separate them: 77% of EcoGPT's written reviews are positive against 97% of Mello's.
EcoGPT ships an update every 5 days, Mello every 4 days. Both last shipped on October 15, 2026.
