Verdict

The call

The clearest difference is ads: Stack Tracker at none against Bullion Calculator's shown. Stack Tracker also leads on ratings volume (12 vs 2). Bullion Calculator's advantage is update cadence (every 3 days vs every 2 months) and review sentiment (100% vs 83%). On price, rating, in-app purchases and monetization model there is nothing between them.
