Both are free to download. Booster Up! sells 10 one-off in-app purchases. Dr. Rocket asks for nothing beyond the download.
Booster Up! holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Booster Up! has 17K ratings behind it against 55, so its average is the more settled of the two. Written reviews complicate that: 72% of Dr. Rocket's written reviews are positive against 19% of Booster Up!'s, so the app with the better star average is not the one people write more warmly about.
Dr. Rocket ships an update every 6 months, Booster Up! weekly. The most recent releases landed on November 1, 2026 and November 9, 2026 respectively.
