Measure anything in any photo. Take a photo or import one from your library, place a reference object you already know the size of, and instantly calculate real-world measurements — lengths, angles, and areas — directly on the image. How it works Set a reference line on a known object in your photo. From there, every measurement you draw is automatically calculated in real scale. What you can measure Ruler — measure distances and lengths Arrow — annotate with directional measurements Angle — measure the angle between any two lines Area — tap points to outline a surface and calculate its area Built for precision Works entirely offline — no internet required Metric and imperial units Pinch to zoom for precise point placement Undo and redo any change Hide or show your reference line at any time Tips for accurate results For best accuracy, make sure your reference object and the object you're measuring are in the same plane, and that the camera was parallel to both when the photo was taken. Perspective distortion affects results. Measurements are estimates based on the reference you provide.

ImageMeter puts measurements and notes directly into your photos. No more hand-drawn sketches that nobody understands: take a photo on site, draw the dimensions where they belong, add notes, detail images, or audio notes, and send a clear document to your clients and colleagues. ImageMeter is used by tradespeople, carpenters, kitchen and interior designers, property managers, sign makers, insurance assessors and many more. ENTER MEASUREMENTS YOUR WAY • Bluetooth laser meters: send measurements straight into the image. ImageMeter supports most laser distance meters with Bluetooth and, where the device allows it, triggers measurements remotely (https://imagemeter.com/manual/bluetooth/devices). • Measure in the image: set a reference, such as a known wall size, a sheet of paper or a known length, and ImageMeter calculates lengths and areas, even on surfaces seen in perspective. • Or simply type in the values from your tape measure. TOOLS FOR EVERY JOB • Lengths, areas, angles, circles and rectangles • Measurement strings and polylines • Counting tool • Text notes, freehand drawings and arrows • Audio notes and detail pictures inside the image • Line styles, colors, font sizes and arrowheads • Brightness, contrast and saturation for poorly lit photos PDF PLANS AND FORMS Import floor plans and drawings from PDF files. ImageMeter takes the scale of the drawing into account, so you can measure right on the plan. Fill your PDF forms directly in the app. EXPORT AND SHARE • Images as JPEG or PNG, annotated PDF documents and PDF reports • Data tables for bills of materials or measurement logs, ready for your spreadsheet • Editable image files for other ImageMeter users YOUR CLOUD, YOUR DATA Sync your images with the cloud storage of your choice: OneDrive, Dropbox, Google Drive, your own Nextcloud/WebDAV server or SFTP.

Verdict
The clearest difference is review sentiment: ImageMeter at 100% against Image Ruler's 18%. ImageMeter also leads on rating (5.0 vs 1.6) and ads (none vs shown). Image Ruler's advantage is monetization model (free vs freemium) and ratings volume (45 vs 1). On price, in-app purchases, device support and iOS requirement there is nothing between them.
