# GrowthUp vs Stacksy

The clearest difference is monetization model: GrowthUp at freemium against Stacksy's subscription. Stacksy's advantage is ads (none vs shown) and update cadence (every 2 days vs every 9 days). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. GrowthUp sells 2 in-app purchases, starting at $14.99 per month and Stacksy sells 5 in-app purchases, starting at $9.99 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 GrowthUp against 5.0 for Stacksy. That said, the two scores are not equally well evidenced: Stacksy has 16 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

GrowthUp ships an update every 9 days, Stacksy every 2 days. Both last shipped on October 11, 2026.
