# Peps vs Stacker

The clearest difference is ads: Peps at none against Stacker's shown. Peps also leads on iOS requirement (14.0 vs 17.0). Stacker's advantage is ratings volume (12 vs 1). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Peps sells 2 in-app purchases, starting at $9.99 per month and Stacker sells 1 in-app purchase, starting at $69.99 per year. 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 Peps against 5.0 for Stacker. That said, the two scores are not equally well evidenced: Stacker has 12 ratings behind it against 1, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 4 days. The most recent releases landed on September 19, 2026 and September 14, 2026 respectively.
