# Mobile Guard vs Stamp Identifier

The clearest difference is rating: Stamp Identifier at 4.4 against Mobile Guard's 3.6. Stamp Identifier also leads on update cadence (every 4 days vs every 2 weeks). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Mobile Guard sells 2 in-app purchases, starting at $9.99 per 7 days and Stamp Identifier sells 2 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Stamp Identifier holds the better App Store score, 4.4 against 3.6. Both are backed by a comparable volume of ratings — 23 and 16 respectively. Written reviews complicate that: 100% of Mobile Guard's written reviews are positive against 94% of Stamp Identifier's, so the app with the better star average is not the one people write more warmly about.

Mobile Guard ships an update every 2 weeks, Stamp Identifier every 4 days. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
