Verdict
The clearest difference is review sentiment: Cards HQ at 67% against Gradea.id's 23%. Cards HQ also leads on rating (4.5 vs 4.0) and ratings volume (186 vs 1). Gradea.id's advantage is ads (none vs shown) and update cadence (every 9 days vs monthly). On price, in-app purchases, monetization model and device support there is nothing between them.
