OMNI AI is free to download; Touch Annotator costs $5.99 up front. OMNI AI sells 3 in-app purchases, starting at $4.99 per month. Touch Annotator asks for nothing beyond the download.
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.
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.
