Verdict
The clearest difference is review sentiment: RecallNote at 88% against PassFinder's 39%. RecallNote also leads on rating (4.3 vs 3.1) and update cadence (every 3 days vs every 3 months). PassFinder's advantage is in-app purchases (none vs 2) and ratings volume (30 vs 3). On price, ads, monetization model and device support there is nothing between them.
