# Screw Identifier vs Tool Identifier

The clearest difference is rating: Tool Identifier at 5.0 against Screw Identifier's 3.5. Screw Identifier's advantage is ratings volume (24 vs 3) and iOS requirement (13.0 vs 16.4). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Screw Identifier sells 8 in-app purchases, starting at $4.99 per 7 days and Tool Identifier sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Tool Identifier holds the better App Store score, 5.0 against 3.5. That said, the two scores are not equally well evidenced: Screw Identifier has 24 ratings behind it against 3, so its average is the more settled of the two.
