# Gravity Runner vs Blue Box Simulator

The clearest difference is ads: Gravity Runner at none against Blue Box Simulator's shown. Gravity Runner also leads on review sentiment (100% vs 79%) and update cadence (every 4 days vs every 2 weeks). Blue Box Simulator's advantage is ratings volume (109 vs 15). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Gravity Runner sells 1 one-off in-app purchase and Blue Box Simulator sells 3 in-app purchases, starting at $0.99 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 — 4.6 for Gravity Runner against 4.5 for Blue Box Simulator. That said, the two scores are not equally well evidenced: Blue Box Simulator has 109 ratings behind it against 15, so its average is the more settled of the two. Written reviews are what separate them: 100% of Gravity Runner's written reviews are positive against 79% of Blue Box Simulator's.
