# Idle Universe vs IdleSphere

The clearest difference is rating: Idle Universe at 4.3 against IdleSphere's 3.8. Idle Universe also leads on ratings volume (1.5K vs 32) and review sentiment (65% vs 47%). IdleSphere's advantage is update cadence (every 8 days vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Idle Universe sells 7 one-off in-app purchases and IdleSphere sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Idle Universe holds the better App Store score, 4.3 against 3.8. That said, the two scores are not equally well evidenced: Idle Universe has 1.5K ratings behind it against 32, so its average is the more settled of the two. Written reviews point the same way: 65% of Idle Universe's written reviews are positive against 47% of IdleSphere's.

Idle Universe ships an update every 3 weeks, IdleSphere every 8 days. The most recent releases landed on October 26, 2026 and October 20, 2026 respectively.
