# De vs Octo Boost

De and Octo Boost both sit at 4.8 stars, but that hides the real split: 100% of Octo Boost's written reviews are positive against 49% of De's. Octo Boost also leads on in-app purchases (none vs 10). De's advantage is ratings volume (3K vs 4). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. De sells 10 one-off in-app purchases. Octo Boost asks for nothing beyond the download.

Octo Boost holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: De has 3K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 49% of De's written reviews are positive against 100% of Octo Boost's.

De ships an update every 10 days, Octo Boost every 9 days. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
