# Stamp Identifier vs Stamp Identifier

The clearest difference is review sentiment: Stamp Identifier at 100% against Stamp Identifier's 50%. Stamp Identifier also leads on update cadence (fortnightly vs every 2 months). Stamp Identifier's advantage is rating (4.0 vs 3.7). On price, ratings volume, 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 8 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Stamp Identifier holds the better App Store score, 4.0 against 3.7. Both are backed by a comparable volume of ratings — 4 and 3 respectively. Written reviews complicate that: 50% of Stamp Identifier's written reviews are positive against 100% of Stamp Identifier's, so the app with the better star average is not the one people write more warmly about.

Stamp Identifier ships an update every 2 months, Stamp Identifier fortnightly. The most recent releases landed on October 30, 2026 and November 6, 2026 respectively.
