# Intergalactic Bible vs DIY Solar System

The clearest difference is rating: Intergalactic Bible at 5.0 against DIY Solar System's 4.5. DIY Solar System's advantage is in-app purchases (none vs 1) and review sentiment (100% vs 67%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Intergalactic Bible sells 1 one-off in-app purchase. DIY Solar System asks for nothing beyond the download.

Intergalactic Bible holds the better App Store score, 5.0 against 4.5. Both are backed by a comparable volume of ratings — 5 and 16 respectively. Written reviews complicate that: 67% of Intergalactic Bible's written reviews are positive against 100% of DIY Solar System's, so the app with the better star average is not the one people write more warmly about.

Intergalactic Bible ships an update every 6 weeks, DIY Solar System every 2 months. The most recent releases landed on October 12, 2026 and October 13, 2026 respectively.
