# Black Keys vs Level3D

The clearest difference is price: Level3D at Free against Black Keys's $0.99. Level3D also leads on rating (5.0 vs 3.4). Black Keys's advantage is update cadence (fortnightly vs every 7 months) and ratings volume (27 vs 1). On ads, in-app purchases, monetization model and device support there is nothing between them.

Level3D is free to download; Black Keys costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Level3D holds the better App Store score, 5.0 against 3.4. That said, the two scores are not equally well evidenced: Black Keys has 27 ratings behind it against 1, so its average is the more settled of the two.

Black Keys ships an update fortnightly, Level3D every 7 months. The most recent releases landed on October 10, 2026 and September 7, 2026 respectively.
