# Zero vs EatTimer

The clearest difference is monetization model: Zero at freemium against EatTimer's subscription. Zero also leads on ratings volume (445K vs 221) and review sentiment (33% vs 13%). EatTimer's advantage is iOS requirement (12.0 vs 17.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Zero sells 10 in-app purchases, starting at $9.99 per month and EatTimer sells 4 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for Zero against 4.8 for EatTimer. That said, the two scores are not equally well evidenced: Zero has 445K ratings behind it against 221, so its average is the more settled of the two. Written reviews are what separate them: 33% of Zero's written reviews are positive against 13% of EatTimer's.

Zero ships an update every 2 weeks, EatTimer every 3 weeks. The most recent releases landed on September 26, 2026 and July 5, 2026 respectively.
