# Scan All vs Flash PDF

Scan All and Flash PDF 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 ship on a similar rhythm, roughly fortnightly. The most recent releases landed on October 25, 2026 and October 30, 2026 respectively.
