# PREP（プレップ） vs Snow

The clearest difference is rating: Snow at 4.9 against PREP（プレップ）'s 2.3. Snow also leads on ads (none vs shown) and ratings volume (949 vs 6). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. PREP（プレップ） sells 2 in-app purchases, starting at $0.99 per month and Snow sells 12 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

Snow holds the better App Store score, 4.9 against 2.3. That said, the two scores are not equally well evidenced: Snow has 949 ratings behind it against 6, so its average is the more settled of the two.
