Verdict
The clearest difference is review sentiment: DigiDecoder at 50% against Radioddity GS's 6%. DigiDecoder also leads on rating (4.5 vs 1.5) and update cadence (every 4 days vs every 2 months). Radioddity GS's advantage is in-app purchases (none vs 3) and ratings volume (48 vs 8). On price, ads and device support there is nothing between them.
