# Procedural vs Zen Checklists

The clearest difference is update cadence: Zen Checklists at every 3 days against Procedural's fortnightly. Zen Checklists also leads on iOS requirement (15.1 vs 18.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Procedural sells 1 in-app purchase, starting at $0.99 per month and Zen Checklists sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Procedural ships an update fortnightly, Zen Checklists every 3 days. The most recent releases landed on July 24, 2026 and August 27, 2026 respectively.
