# Stamp Value Stamp Identifier vs DefendMax

The clearest difference is review sentiment: DefendMax at 100% against Stamp Value Stamp Identifier's 45%. DefendMax also leads on ads (none vs shown) and iOS requirement (15.5 vs 18.0). Stamp Value Stamp Identifier's advantage is ratings volume (3.6K vs 14) and rating (4.6 vs 4.4). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Stamp Value Stamp Identifier sells 6 in-app purchases, starting at $4.99 per 7 days and DefendMax sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Stamp Value Stamp Identifier holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Stamp Value Stamp Identifier has 3.6K ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 45% of Stamp Value Stamp Identifier's written reviews are positive against 100% of DefendMax's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
