Verdict
The clearest difference is ads: Spark at none against TrainTracker App's shown. Spark also leads on rating (5.0 vs 4.8) and iOS requirement (15.1 vs 17.6). TrainTracker App's advantage is update cadence (every 3 days vs every 4 months) and monetization model (free vs free with in-app purchases). On price, ratings volume, in-app purchases and device support there is nothing between them.
