# DeepChat vs Promptastic

The clearest difference is update cadence: DeepChat at every 4 days against Promptastic's every 3 months. DeepChat also leads on rating (3.9 vs 3.5) and review sentiment (65% vs 50%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. DeepChat sells 4 in-app purchases, starting at $4.99 per 7 days and Promptastic sells 4 in-app purchases, starting at $2.99 per year. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: DeepChat has 19 ratings behind it against 2, so its average is the more settled of the two.
