Verdict
The clearest difference is price: GOES Viewer at Free against DawnTracker's $2.99. GOES Viewer also leads on ratings volume (15 vs 1) and iOS requirement (13.0 vs 26.0). DawnTracker's advantage is update cadence (every 3 days vs every 2 months). On rating, ads, in-app purchases and device support there is nothing between them.
