# eevie vs 2zero Climathon

The clearest difference is rating: 2zero Climathon at 5.0 against eevie's 3.7. eevie's advantage is ratings volume (15 vs 1) and review sentiment (61% vs 48%). On price, update cadence, ads and in-app purchases there is nothing between them.

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

2zero Climathon holds the better App Store score, 5.0 against 3.7. That said, the two scores are not equally well evidenced: eevie has 15 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 61% of eevie's written reviews are positive against 48% of 2zero Climathon's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on October 24, 2026 and October 23, 2026 respectively.
