# Project vs ZBM

The clearest difference is rating: Project at 4.6 against ZBM's 3.7. Project also leads on monetization model (free with in-app purchases vs subscription) and ratings volume (1.5K vs 3). ZBM's advantage is ads (none vs shown) and iOS requirement (10.0 vs 15.0). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Project sells 18 one-off in-app purchases and ZBM sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Project holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: Project has 1.5K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 72% of Project's written reviews are positive against 62% of ZBM's.

Project ships an update monthly, ZBM fortnightly. The most recent releases landed on October 15, 2026 and October 10, 2026 respectively.
