# LuckGrib vs Nullschool

The clearest difference is ratings volume: LuckGrib at 338 against Nullschool's 27. Nullschool's advantage is update cadence (monthly vs every 2 months) and chart position (#41 vs #185). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. LuckGrib sells 6 one-off in-app purchases and Nullschool sells 3 in-app purchases, starting at $2.99 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 — 4.9 for LuckGrib against 5.0 for Nullschool. That said, the two scores are not equally well evidenced: LuckGrib has 338 ratings behind it against 27, so its average is the more settled of the two. Written reviews are what separate them: 93% of LuckGrib's written reviews are positive against 100% of Nullschool's.

LuckGrib ships an update every 2 months, Nullschool monthly. The most recent releases landed on September 25, 2026 and September 23, 2026 respectively.
