# Stamp Identifier ° vs Stamp Identifier

The clearest difference is rating: Stamp Identifier ° at 4.6 against Stamp Identifier's 4.0. Stamp Identifier ° also leads on ratings volume (17 vs 4). Stamp Identifier's advantage is review sentiment (100% vs 80%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Stamp Identifier ° sells 2 in-app purchases, starting at $4.99 per 7 days and Stamp 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.
