Verdict
The clearest difference is rating: Data Diggers at 3.0 against Decoder's 1.2. Data Diggers also leads on update cadence (every 6 weeks vs every 7 months). Decoder's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, review sentiment, ratings volume and in-app purchases there is nothing between them.
