User Reviews

Users praise Annotium as a feature-rich tool useful for professional work, with easy capture and annotation. However, recurring issues limit its practicality: intrusive ads and unclear pricing, user-interface/navigation problems (especially in landscape mode), limited editing/saving workflows, drawing that lacks true freehand curves and erasing, and reduced image quality after saving. These recurring points suggest strong core value but persistent UX and workflow friction that affect everyday use.

Pros

Feature-rich annotation toolkit with more tools and capabilities than typical phone-based editors.
Very useful for professional use cases (site work, medical X-ray annotations) and quick capture/markup workflows.
Easy capture and quick annotation process that generally works well for on-the-go tasks.
No mandatory in-app purchases for core features (apparent from user feedback).

Cons

Intrusive ads and unclear premium pricing; ads can pop up during or after saving and the value/scope of the paid version is unclear.
Clunky UI/UX and navigation problems; landscape mode hides tools under the bottom OS bar and overall interface is not intuitive.
Saving/editing limitations; cannot edit annotations after saving and drafts/save flow are unclear or missing.
Drawing limitations; lack of a continuous freehand curve, awkward point-forcing drawing, no eraser, and limited zoom control.
Image quality often degrades after saving, reducing the usefulness of precise measurements and annotations.

It's a little hard to navigate the menu, but the most frustrating part is the lack of a continuous freehand curve. Closest thing it has is a bezier curve that you draw first with 2 points, then adjust the 3rd. Sometimes you just want to draw a squiggle, and you can't easily!

At first I thought it was perfect with its line measurement annotation <---130cm---> But then it got confusing. Save? Yes. Then the annoying video ads pop up taking over the entire screen. Can't get out without quitting the app. I don't see a paid version. After it has been saved the annotations aren't editable. Text size changes randomly between annotations. There is no central preferences option. I wish it was better thought out. Maybe I got it wrong. I read the manual on their website.
