# StackTrax vs Optimized Human

The clearest difference is update cadence: StackTrax at daily against Optimized Human's fortnightly. StackTrax also leads on ratings volume (7 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. StackTrax sells 2 in-app purchases, starting at $4.99 per month and Optimized Human sells 2 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for StackTrax against 5.0 for Optimized Human. That said, the two scores are not equally well evidenced: StackTrax has 7 ratings behind it against 1, so its average is the more settled of the two.

StackTrax ships an update daily, Optimized Human fortnightly. The most recent releases landed on October 6, 2026 and October 1, 2026 respectively.
