# Gravity vs Miaru

The clearest difference is rating: Miaru at 4.7 against Gravity's 4.1. Miaru also leads on update cadence (every 3 days vs every 9 days). Gravity's advantage is ratings volume (35 vs 7) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Gravity sells 6 in-app purchases, starting at $4.99 per month and Miaru sells 2 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

Miaru holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: Gravity has 35 ratings behind it against 7, so its average is the more settled of the two.

Gravity ships an update every 9 days, Miaru every 3 days. Both last shipped on October 25, 2026.
