# MO vs Units

The clearest difference is rating: MO at 5.0 against Units's 4.4. Units's advantage is ratings volume (15 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

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

MO holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Units has 15 ratings behind it against 2, so its average is the more settled of the two.
