# Booster Up! vs Ellipse

Booster Up! and Ellipse both sit at 4.6 stars, but that hides the real split: 79% of Ellipse's written reviews are positive against 19% of Booster Up!'s. Ellipse also leads on ads (none vs shown). Booster Up!'s advantage is update cadence (weekly vs monthly) and ratings volume (17K vs 2K). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Booster Up! sells 14 one-off in-app purchases and Ellipse sells 3 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 — 4.6 for Booster Up! against 4.7 for Ellipse. That said, the two scores are not equally well evidenced: Booster Up! has 17K ratings behind it against 2K, so its average is the more settled of the two. Written reviews are what separate them: 19% of Booster Up!'s written reviews are positive against 79% of Ellipse's.

Booster Up! ships an update weekly, Ellipse monthly. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
