Verdict
The clearest difference is in-app purchases: passportbask at none against Stamp Identifier's 3. passportbask also leads on ads (none vs shown) and update cadence (weekly vs every 4 weeks). Stamp Identifier's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 26.5). On price there is nothing between them.
