# Go Space vs Booster Up!

Go Space and Booster Up! both sit at 4.5 stars, but that hides the real split: 50% of Go Space's written reviews are positive against 19% of Booster Up!'s. Booster Up!'s advantage is update cadence (weekly vs every 3 months) and ratings volume (17K vs 4). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Go Space sells 2 one-off in-app purchases and Booster Up! sells 14 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for Go Space against 4.6 for Booster Up!. That said, the two scores are not equally well evidenced: Booster Up! has 17K ratings behind it against 4, so its average is the more settled of the two. Written reviews are what separate them: 50% of Go Space's written reviews are positive against 19% of Booster Up!'s.

Go Space ships an update every 3 months, Booster Up! weekly. The most recent releases landed on October 21, 2026 and October 29, 2026 respectively.
