# ShellLens vs Shell Identifier

The clearest difference is iOS requirement: Shell Identifier at 15.0 against ShellLens's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. ShellLens sells 2 in-app purchases, starting at $3.99 per 7 days and Shell Identifier sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
