# AQUASTARS vs Adrenaline

The clearest difference is update cadence: AQUASTARS at every 4 months against Adrenaline's every 12 months. Adrenaline's advantage is ratings volume (5 vs 1). On price, rating, ads and in-app purchases 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 — 5.0 for AQUASTARS against 5.0 for Adrenaline. That said, the two scores are not equally well evidenced: Adrenaline has 5 ratings behind it against 1, so its average is the more settled of the two.

AQUASTARS ships an update every 4 months, Adrenaline every 12 months. Both last shipped on November 3, 2026.
