# Idle World vs Planet Builder

The clearest difference is ratings volume: Idle World at 34K against Planet Builder's 14. Planet Builder's advantage is update cadence (every 6 days vs every 4 weeks) and rating (4.8 vs 4.5). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Idle World sells 12 in-app purchases, starting at $5.99 per 7 days and Planet Builder sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Planet Builder holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Idle World has 34K ratings behind it against 14, so its average is the more settled of the two.

Idle World ships an update every 4 weeks, Planet Builder every 6 days. The most recent releases landed on October 25, 2026 and October 23, 2026 respectively.
