Verdict

The call

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.

CostPrice · In-app purchases · Ads · Monetization

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.
