# Factory vs BLEASS Monolit

The clearest difference is update cadence: Factory at every 4 months against BLEASS Monolit's every 12 months. Factory also leads on ratings volume (487 vs 83). BLEASS Monolit's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 17.6). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Factory sells 1 one-off in-app purchase and BLEASS Monolit sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Factory against 4.7 for BLEASS Monolit. That said, the two scores are not equally well evidenced: Factory has 487 ratings behind it against 83, so its average is the more settled of the two. Written reviews are what separate them: 81% of Factory's written reviews are positive against 83% of BLEASS Monolit's.

Factory ships an update every 4 months, BLEASS Monolit every 12 months. Both last shipped on October 24, 2026.
