# Shidosha vs GradeVine

The clearest difference is in-app purchases: Shidosha at none against GradeVine's 4. Shidosha also leads on iOS requirement (15.1 vs 18.2). GradeVine's advantage is ratings volume (9 vs 1). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. GradeVine sells 4 in-app purchases, starting at $4.99 per month. Shidosha asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Shidosha against 5.0 for GradeVine. That said, the two scores are not equally well evidenced: GradeVine has 9 ratings behind it against 1, so its average is the more settled of the two.
