# Crucible vs Stack Tracker

The clearest difference is monetization model: Stack Tracker at free with in-app purchases against Crucible's subscription. Stack Tracker also leads on ratings volume (12 vs 2). Crucible's advantage is update cadence (every 3 days vs every 2 months) and review sentiment (100% vs 83%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Crucible sells 1 in-app purchase, starting at $6.99 per month and Stack Tracker sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Crucible 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. Written reviews point the same way: 100% of Crucible's written reviews are positive against 83% of Stack Tracker's.

Crucible ships an update every 3 days, Stack Tracker every 2 months. The most recent releases landed on October 22, 2026 and October 24, 2026 respectively.
