Verdict

The call

The clearest difference is rating: Busbetrieb at 5.0 against Full Screen Viewer's 3.7. Busbetrieb also leads on ads (none vs shown) and update cadence (every 3 days vs fortnightly). Full Screen Viewer's advantage is ratings volume (3 vs 1) and iOS requirement (13.0 vs 16.6). On price, in-app purchases, monetization model and device support there is nothing between them.
