Verdict
The clearest difference is review sentiment: Gretio at 72% against Bosch Mobile Scan's 11%. Gretio also leads on rating (3.8 vs 1.9) and update cadence (fortnightly vs every 10 months). Bosch Mobile Scan's advantage is ratings volume (131 vs 23) and iOS requirement (8.0 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.
