Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Idle Universe sells 7 one-off in-app purchases. Planet simulation asks for nothing beyond the download.
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.
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.
