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. ## Key features - Measure objects on photos - Use a known object as a reference - Supports metric and imperial units - Intuitive editing interface - Organize photos easily - Zoom for precision ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | imageRulerPro | $0.99 | one-time | | Medium Tip | $2.99 | one-time | | Small Tip | $0.99 | one-time | | Big Tip | $4.99 | one-time | | Small Tip | $0.99 | one-time | | Big tip | $4.99 | one-time | | Medium Tip | $2.99 | one-time | ## Recent user reviews (10 of 17) All indexed reviews: https://appshunter.io/ios/app/image-ruler-measures/id1474481911/reviews.md ### 1/5 — Non functional *2026-01-09* This app doesn’t work on the latest version of iOS. I can open an image but I can’t do anything else with it. The UI elements appear to be from several versions of iOS ago, so it’s likely this app hasn’t been developed for quite awhile. It’s a shame, because this is a very useful niche gadget to have. ### 2/5 — Cant zoom ! *2025-05-24* U cant measure anything while zooming ! ### 1/5 — App has been abandoned *2024-12-03* This app crashes and won’t load due to not being updated for a long time. I reached out to the developer with no response. It appears to be forfeit. ### 1/5 — Worst app *2024-07-30* This app does not work. You cant click on anything.
