# 2zero Climathon vs EcoHero

The clearest difference is review sentiment: EcoHero at 91% against 2zero Climathon's 48%. EcoHero also leads on ratings volume (27 vs 1) and iOS requirement (12.0 vs 15.0). 2zero Climathon's advantage is in-app purchases (none vs 8) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. EcoHero sells 8 in-app purchases, starting at $1.99 per month. 2zero Climathon asks for nothing beyond the download.

2zero Climathon holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: EcoHero has 27 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 48% of 2zero Climathon's written reviews are positive against 91% of EcoHero's, so the app with the better star average is not the one people write more warmly about.

2zero Climathon ships an update every 2 weeks, EcoHero monthly. Both last shipped on November 3, 2026.
