# Proton Pass vs zdo

Proton Pass and zdo 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. Proton Pass sells 2 in-app purchases, starting at $35.90 per year and zdo sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on November 10, 2026 and November 6, 2026 respectively.
