# Milki vs Opening Bell

The clearest difference is ratings volume: Milki at 107 against Opening Bell's 4. Milki also leads on device support (3 vs 1). Opening Bell's advantage is update cadence (every 4 days vs fortnightly). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Milki sells 3 in-app purchases, starting at $11.99 per year and Opening Bell sells 2 in-app purchases, starting at $2.99 per month. 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 Milki against 5.0 for Opening Bell. That said, the two scores are not equally well evidenced: Milki has 107 ratings behind it against 4, so its average is the more settled of the two.
