ReceptionRating · Positive reviews · Number of ratings

OMNI AI holds the better App Store score, 4.4 against 1.0. That said, the two scores are not equally well evidenced: OMNI AI has 77 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 60% of Touch Annotator's written reviews are positive against 44% of OMNI AI's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Touch Annotator ships an update every 3 weeks, OMNI AI every 5 days. The most recent releases landed on June 10, 2026 and October 23, 2026 respectively.
