PixDuo is a specialized tool designed for users who need to visually compare two images directly. The primary function is its intuitive side-by-side and split-screen viewer, which allows photos to be placed adjacent to each other for a detailed, pixel-level comparison. This is particularly useful for professionals like contractors documenting renovation progress, fitness coaches tracking client transformations, or designers comparing different versions of a layout. The app includes basic but effective manipulation tools such as zooming, panning in sync, and adjusting alignment, which help in making accurate assessments. Annotations can also be added to highlight specific changes or areas of interest. However, reviews indicate the image editing capabilities are quite basic, positioning PixDuo more as a dedicated comparison viewer than a full-fledged editor. Some users note that while the core comparison function is reliable, the user interface can feel slightly dated compared to some other photo apps. The lack of cloud sync features is another noted limitation, making it primarily a local, on-device tool. For straightforward, focused photo comparison without extra complexity, PixDuo delivers on its core promise effectively.
