# Opus vs Chat with o1

The clearest difference is rating: Opus at 5.0 against Chat with o1's 4.5. Opus also leads on device support (3 vs 1). Chat with o1's advantage is ads (none vs shown) and ratings volume (8 vs 1). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

Both are free to download. Opus sells 1 one-off in-app purchase and Chat with o1 sells 4 in-app purchases, starting at $19.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Opus holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Chat with o1 has 8 ratings behind it against 1, so its average is the more settled of the two.
