# Shaft Run vs Stacks Up

The clearest difference is rating: Shaft Run at 5.0 against Stacks Up's 3.9. Shaft Run also leads on update cadence (every 2 months vs every 20 months). Stacks Up's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price there is nothing between them.

Both are free to download. Shaft Run sells 10 one-off in-app purchases. Stacks Up asks for nothing beyond the download.

Shaft Run holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: Stacks Up has 34 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Shaft Run's written reviews are positive against 33% of Stacks Up's, so the app with the better star average is not the one people write more warmly about.

Shaft Run ships an update every 2 months, Stacks Up every 20 months. The most recent releases landed on October 20, 2026 and October 21, 2026 respectively.
