# Sandbox vs Grainfall

The clearest difference is rating: Grainfall at 5.0 against Sandbox's 4.4. Grainfall also leads on ads (none vs shown). Sandbox's advantage is ratings volume (9.2K vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Sandbox sells 1 one-off in-app purchase and Grainfall sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Grainfall holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Sandbox has 9.2K ratings behind it against 1, so its average is the more settled of the two.
