Oyster ◦ Sea Shell Identifier and Shell ID are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support 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. Oyster ◦ Sea Shell Identifier sells 2 in-app purchases, starting at $2.99 per 7 days and Shell ID sells 2 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.
