# WatchGrid vs Zen Passwords

WatchGrid and Zen Passwords are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. WatchGrid sells 1 one-off in-app purchase and Zen Passwords sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

WatchGrid ships an update every 6 days, Zen Passwords weekly. The most recent releases landed on November 11, 2026 and October 31, 2026 respectively.
