# Sandboxx vs SGD

Sandboxx and SGD both sit at 4.9 stars, but that hides the real split: 100% of SGD's written reviews are positive against 73% of Sandboxx's. SGD also leads on monetization model (free vs free with in-app purchases). Sandboxx's advantage is ratings volume (178K vs 7) and chart position (#93 vs unranked). On price, rating, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

On the App Store both sit at effectively the same score — 4.9 for Sandboxx against 5.0 for SGD. That said, the two scores are not equally well evidenced: Sandboxx has 178K ratings behind it against 7, so its average is the more settled of the two. Written reviews are what separate them: 73% of Sandboxx's written reviews are positive against 100% of SGD's.
