# iM.Master vs CyberBrick

The clearest difference is rating: CyberBrick at 3.8 against iM.Master's 2.8. iM.Master's advantage is ratings volume (90 vs 11) and review sentiment (47% vs 38%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

CyberBrick holds the better App Store score, 3.8 against 2.8. That said, the two scores are not equally well evidenced: iM.Master has 90 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 47% of iM.Master's written reviews are positive against 38% of CyberBrick's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 1, 2026 and October 9, 2026 respectively.
