Verdict
Idle Universe and Sync Ball both sit at 4.3 stars, but that hides the real split: 65% of Idle Universe's written reviews are positive against 18% of Sync Ball's. Sync Ball's advantage is in-app purchases (none vs 7) and update cadence (every 5 days vs every 3 weeks). On price, rating, ratings volume and ads there is nothing between them.

Sync Ball holds the better App Store score, 4.4 against 4.3. Both are backed by a comparable volume of ratings — 1.5K and 1.2K respectively. Written reviews complicate that: 65% of Idle Universe's written reviews are positive against 18% of Sync Ball's, so the app with the better star average is not the one people write more warmly about.
Idle Universe ships an update every 3 weeks, Sync Ball every 5 days. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
