# Universal Numbers vs 3D Star Map

The clearest difference is review sentiment: 3D Star Map at 100% against Universal Numbers's 67%. 3D Star Map also leads on update cadence (every 2 weeks vs monthly) and iOS requirement (12.0 vs 16.6). Universal Numbers's advantage is rating (4.9 vs 4.5). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Universal Numbers holds the better App Store score, 4.9 against 4.5. Both are backed by a comparable volume of ratings — 24 and 10 respectively. Written reviews complicate that: 67% of Universal Numbers's written reviews are positive against 100% of 3D Star Map's, so the app with the better star average is not the one people write more warmly about.

Universal Numbers ships an update monthly, 3D Star Map every 2 weeks. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
