# Second Eye vs Archius

Second Eye and Archius 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. Second Eye sells 2 in-app purchases, starting at $3.99 per month and Archius sells 1 in-app purchase, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.
