# Circa vs DD

The clearest difference is in-app purchases: Circa at none against DD's 3. DD's advantage is update cadence (every 4 days vs every 3 weeks) and ratings volume (14 vs 2). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. DD sells 3 one-off in-app purchases. Circa asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Circa against 5.0 for DD. That said, the two scores are not equally well evidenced: DD has 14 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Circa ships an update every 3 weeks, DD every 4 days. The most recent releases landed on October 17, 2026 and November 1, 2026 respectively.
