Whether you are a keeper, breeder, or enthusiast, you can obtain accurate measurements in seconds — all directly on your device and without collecting any personal data. How it works Take a top-down photo of your animal next to a reference object (a ruler, tape measure, phone, bank card, etc.). Mark the start and end of the reference object to set the scale. Add points along the animal’s body for precise measurement. Adjust points by dragging them for maximum accuracy. Save your results and organize them by individual animals. Everything happens on-device, securely and privately.

Track growth over time, maintain accurate records, and store all measurements in one place. Perfect for snakes, lizards, and any animal whose size can be estimated through a reference object.

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.
