# PDF Studio vs Calendria

PDF Studio and Calendria 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. PDF Studio sells 3 in-app purchases, starting at $5.99 per month and Calendria sells 1 in-app purchase, starting at $79.99 per year. Whichever you choose, the download price is not the number that matters.

PDF Studio ships an update fortnightly, Calendria weekly. The most recent releases landed on October 7, 2026 and October 21, 2026 respectively.
