# Sumdog vs 1

The clearest difference is in-app purchases: 1 at none against Sumdog's 1. 1 also leads on review sentiment (73% vs 64%). Sumdog's advantage is ratings volume (1.6K vs 5). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Sumdog sells 1 in-app purchase, starting at $8.99 per month. 1 asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.2 for Sumdog against 4.2 for 1. That said, the two scores are not equally well evidenced: Sumdog has 1.6K ratings behind it against 5, so its average is the more settled of the two. Written reviews are what separate them: 64% of Sumdog's written reviews are positive against 73% of 1's.

Sumdog ships an update every 2 months, 1 every 3 months. The most recent releases landed on September 22, 2026 and September 21, 2026 respectively.
