Structure is a graphing app for professionals. With a variety of shapes, markers and more, Structure is the perfect tool for anyone looking to graph their next project. Structure allows users to graph shapes, calculate area and linear feet, color code shapes, add markers to indicate areas of interest and export the final output to a PNG or PDF. Whether you're a professional in need of a graphing tool or an enthusiast looking to graph your latest home project, Structure is for you. ## Features There are multiple objects that can be added to a graph. Square - A square is a four sided shape that has four lines at 90 degree angles. Dragging a corner will scale the shape in both height and width. Shape - A shape is dynamic and can have any number of points. By default, a shape has four points. Double tapping a line will add an additional point. Points can also be removed by tapping a line and then using the action menu in the bottom right corner of the screen. Dragging a corner will not impact the other corners in the shape. Circle - A circle can be added with a radius of any size. Ovals are coming soon. Lines - A line can be added as a solid line, a dotted line or an arrow. Text - A text label can be added to the graph, with a limit of 32 characters. Rectangles and structures each have an option to name a graph, which creates a text label within the shape. Markers - Markers can be added to indicate areas of interest. Markers can be customized to your needs and can also include images. Attaching images to markers is only available to Premium users. Objects - Objects can be added to indicate real-world items, such as trees, bushes, flowers and more. New objects are being added with each new release. Objects for the interior and exterior of a home are coming soon. Each shape can be customized (line width, line color, background color, etc.) by double tapping the shape or using the action menu in the bottom right corner of the screen while the shape is selected. More objects coming soon! ## Premium The Structure Premium subscription gives users additional features and cloud storage for $4.99 per month.

Verdict

The call

The clearest difference is rating: Structure Graphing at 4.5 against iDesign's 2.6. Structure Graphing also leads on update cadence (weekly vs every 3 months). iDesign's advantage is review sentiment (50% vs 25%) and device support (3 vs 1). On price, ratings volume, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Structure Graphing holds the better App Store score, 4.5 against 2.6. Both are backed by a comparable volume of ratings — 87 and 60 respectively. Written reviews complicate that: 50% of iDesign's written reviews are positive against 25% of Structure Graphing's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iDesign ships an update every 3 months, Structure Graphing weekly. The most recent releases landed on November 1, 2026 and October 20, 2026 respectively.
