Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. iMark · Image Annotation Tool sells 4 one-off in-app purchases and Memo sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
iMark · Image Annotation Tool holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: iMark · Image Annotation Tool has 384 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 72% of iMark · Image Annotation Tool's written reviews are positive against 75% of Memo's, so the app with the better star average is not the one people write more warmly about.
iMark · Image Annotation Tool ships an update every 2 months, Memo every 4 days. The most recent releases landed on November 2, 2026 and October 30, 2026 respectively.
