Verdict

The call

The clearest difference is in-app purchases: Planet simulation at none against Idle Universe's 7. Planet simulation also leads on review sentiment (74% vs 65%) and iOS requirement (13.0 vs 15.0). Idle Universe's advantage is update cadence (every 3 weeks vs every 8 months) and rating (4.3 vs 3.9). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Idle Universe holds the better App Store score, 4.3 against 3.9. That said, the two scores are not equally well evidenced: Idle Universe has 1.5K ratings behind it against 165, so its average is the more settled of the two. Written reviews complicate that: 74% of Planet simulation's written reviews are positive against 65% of Idle Universe's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Planet simulation ships an update every 8 months, Idle Universe every 3 weeks. The most recent releases landed on October 9, 2026 and October 15, 2026 respectively.
