# T vs Convertology

The clearest difference is rating: T at 4.6 against Convertology's 4.0. T also leads on ratings volume (208 vs 1) and iOS requirement (16.0 vs 18.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. T sells 4 in-app purchases, starting at $2.99 per 7 days and Convertology sells 2 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

T holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: T has 208 ratings behind it against 1, so its average is the more settled of the two.

T ships an update every 2 weeks, Convertology every 6 days. The most recent releases landed on November 8, 2026 and October 31, 2026 respectively.
