# GoTall vs Dunk By

The clearest difference is ads: Dunk By at none against GoTall's shown. Dunk By also leads on rating (5.0 vs 4.6) and update cadence (every 3 days vs every 9 days). GoTall's advantage is ratings volume (6.8K vs 1) and iOS requirement (15.4 vs 18.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. GoTall sells 15 in-app purchases, starting at $1.99 per 7 days and Dunk By sells 1 in-app purchase, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Dunk By holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: GoTall has 6.8K ratings behind it against 1, so its average is the more settled of the two.

GoTall ships an update every 9 days, Dunk By every 3 days. The most recent releases landed on October 19, 2026 and October 10, 2026 respectively.
