# Idle evolution vs EcoBuilder

The clearest difference is rating: Idle evolution at 4.6 against EcoBuilder's 4.0. Idle evolution also leads on ratings volume (5.9K vs 4). EcoBuilder's advantage is in-app purchases (none vs 22) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Idle evolution sells 22 in-app purchases, starting at $1.99 per 7 days. EcoBuilder asks for nothing beyond the download.

Idle evolution holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Idle evolution has 5.9K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 75% of Idle evolution's written reviews are positive against 100% of EcoBuilder's, so the app with the better star average is not the one people write more warmly about.

Idle evolution ships an update every 2 months, EcoBuilder every 3 weeks. Both last shipped on October 24, 2026.
