Verdict

The call

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.
