# HeightGPT vs Taller

The clearest difference is review sentiment: HeightGPT at 83% against Taller's 0%. Taller's advantage is rating (4.7 vs 4.4) and ratings volume (122 vs 14). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. HeightGPT sells 2 in-app purchases, starting at $3.99 per 7 days and Taller sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Taller holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Taller has 122 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 83% of HeightGPT's written reviews are positive against 0% of Taller's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on June 1, 2026 and September 16, 2026 respectively.
