# C vs Dosion

The clearest difference is update cadence: C at every 5 days against Dosion's every 9 days. C also leads on ratings volume (5 vs 1) and iOS requirement (16.0 vs 18.0). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. C sells 2 in-app purchases, starting at $4.99 per month and Dosion sells 2 in-app purchases, starting at $4.99 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 — 5.0 for C against 5.0 for Dosion. That said, the two scores are not equally well evidenced: C has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

C ships an update every 5 days, Dosion every 9 days. Both last shipped on October 24, 2026.
