# Stamp Identifier AI Value Find vs Postcard Archive

The clearest difference is monetization model: Postcard Archive at free against Stamp Identifier AI Value Find's free with in-app purchases. Postcard Archive also leads on rating (5.0 vs 4.7) and update cadence (every 5 days vs fortnightly). Stamp Identifier AI Value Find's advantage is ratings volume (12 vs 1) and iOS requirement (15.1 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Stamp Identifier AI Value Find sells 8 in-app purchases, starting at $4.49 per 7 days and Postcard Archive sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Postcard Archive holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Stamp Identifier AI Value Find has 12 ratings behind it against 1, so its average is the more settled of the two.

Stamp Identifier AI Value Find ships an update fortnightly, Postcard Archive every 5 days. The most recent releases landed on November 5, 2026 and October 31, 2026 respectively.
