# Bullion Calculator vs Stack Tracker

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.

Both are free to download. Bullion Calculator sells 1 one-off in-app purchase and Stack Tracker sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Bullion Calculator holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Stack Tracker has 12 ratings behind it against 2, so its average is the more settled of the two.
