# Idle Space Force vs Terradome 3D

Idle Space Force and Terradome 3D both sit at 4.7 stars, but that hides the real split: 71% of Idle Space Force's written reviews are positive against 27% of Terradome 3D's. Terradome 3D's advantage is update cadence (weekly vs every 3 weeks) and ratings volume (3.6K vs 551). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Idle Space Force sells 8 one-off in-app purchases and Terradome 3D sells 16 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 — 4.7 for Idle Space Force against 4.6 for Terradome 3D. That said, the two scores are not equally well evidenced: Terradome 3D has 3.6K ratings behind it against 551, so its average is the more settled of the two. Written reviews are what separate them: 71% of Idle Space Force's written reviews are positive against 27% of Terradome 3D's.

Idle Space Force ships an update every 3 weeks, Terradome 3D weekly. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
