# Run Window vs KoopAI

The clearest difference is ratings volume: Run Window at 11 against KoopAI's 2. Run Window also leads on device support (3 vs 1). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Run Window sells 2 in-app purchases, starting at $5.99 per month and KoopAI sells 2 in-app purchases, starting at $19.99 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 Run Window against 5.0 for KoopAI. That said, the two scores are not equally well evidenced: Run Window has 11 ratings behind it against 2, so its average is the more settled of the two.
