# GreaseBook vs HMI Editor

The clearest difference is rating: HMI Editor at 4.7 against GreaseBook's 3.8. GreaseBook's advantage is in-app purchases (none vs 3) and update cadence (every 2 weeks vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. HMI Editor sells 3 one-off in-app purchases. GreaseBook asks for nothing beyond the download.

HMI Editor holds the better App Store score, 4.7 against 3.8. That said, the two scores are not equally well evidenced: GreaseBook has 64 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 85% of GreaseBook's written reviews are positive against 75% of HMI Editor's, so the app with the better star average is not the one people write more warmly about.

GreaseBook ships an update every 2 weeks, HMI Editor every 2 months. The most recent releases landed on November 1, 2026 and October 31, 2026 respectively.
