# Re vs Diagram

The clearest difference is in-app purchases: Diagram at none against Re's 3. Re's advantage is ratings volume (10 vs 2). On price, rating, review sentiment and ads there is nothing between them.

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

On the App Store both sit at effectively the same score — 5.0 for Re against 5.0 for Diagram. That said, the two scores are not equally well evidenced: Re has 10 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.
