# Pululu vs Gravity

The clearest difference is rating: Pululu at 4.7 against Gravity's 4.1. Gravity's advantage is ads (none vs shown) and review sentiment (69% vs 54%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Pululu sells 6 in-app purchases, starting at $6.99 per month and Gravity sells 6 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Pululu holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: Gravity has 39 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 54% of Pululu's written reviews are positive against 69% of Gravity's, so the app with the better star average is not the one people write more warmly about.

Pululu ships an update weekly, Gravity every 9 days. The most recent releases landed on October 30, 2026 and November 1, 2026 respectively.
