# Quitzilla vs ZELLU

The clearest difference is update cadence: ZELLU at every 2 weeks against Quitzilla's every 10 months. ZELLU also leads on device support (3 vs 1) and iOS requirement (15.1 vs 26.0). Quitzilla's advantage is ratings volume (1.5K vs 15). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Quitzilla sells 9 in-app purchases, starting at $5.99 per 7 days and ZELLU sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ZELLU holds the better App Store score, 4.9 against 4.8. That said, the two scores are not equally well evidenced: Quitzilla has 1.5K ratings behind it against 15, so its average is the more settled of the two.

Quitzilla ships an update every 10 months, ZELLU every 2 weeks. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
