Verdict
The clearest difference is rating: One at 2.3 against TransTone's 1.0. One also leads on ratings volume (188 vs 2) and review sentiment (14% vs 0%). TransTone's advantage is in-app purchases (none vs 10) and update cadence (every 9 days vs monthly). On price, ads and device support there is nothing between them.

Both are free to download. One sells 10 one-off in-app purchases. TransTone asks for nothing beyond the download.
One holds the better App Store score, 2.3 against 1.0. That said, the two scores are not equally well evidenced: One has 188 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 14% of One's written reviews are positive against 0% of TransTone's.
One ships an update monthly, TransTone every 9 days. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
