# Firstgrin vs NÜR

The clearest difference is in-app purchases: NÜR at none against Firstgrin's 8. NÜR also leads on ads (none vs shown). Firstgrin's advantage is ratings volume (26 vs 3) and iOS requirement (15.0 vs 17.6). On price, rating, update cadence and device support there is nothing between them.

Both are free to download. Firstgrin sells 8 in-app purchases, starting at $4.99 per month. NÜR asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Firstgrin against 5.0 for NÜR. That said, the two scores are not equally well evidenced: Firstgrin has 26 ratings behind it against 3, so its average is the more settled of the two.
