Verdict
The clearest difference is review sentiment: Postbank at 63% against OLB appTAN's 18%. Postbank also leads on rating (4.7 vs 3.0) and update cadence (every 5 weeks vs every 9 months). OLB appTAN's advantage is monetization model (free vs free with in-app purchases). On price, ads, in-app purchases and device support there is nothing between them.
