# Standly vs GoTall AI

The clearest difference is rating: GoTall AI at 4.8 against Standly's 4.6. Standly's advantage is ratings volume (115 vs 19) and iOS requirement (15.1 vs 18.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Standly sells 4 in-app purchases, starting at $4.99 per 7 days and GoTall AI sells 3 in-app purchases, starting at $17.99 per month. Whichever you choose, the download price is not the number that matters.

GoTall AI holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Standly has 115 ratings behind it against 19, so its average is the more settled of the two.

Standly ships an update every 3 weeks, GoTall AI monthly. Both last shipped on October 24, 2026.
