Mesurix finds your ring size right on your screen. No plastic sizers, no printable guesswork charts, no waiting for a kit in the mail — measure a ring or a finger in under a minute and get the size in every major standard. RING SIZER — TWO WAYS TO MEASURE • Place a ring: lay any well-fitting ring flat on the screen and scale the circle until it matches the inside edge. The most accurate at-home method. • Measure a finger: rest your finger on the screen and fit the circle to the widest part of the base, just past the knuckle. • Fine-tune in 0.1 mm steps — one full ring size is only about 0.8 mm, so precision is everything. • Between sizes? Mesurix tells you which one to choose, so the ring always passes the knuckle. EVERY SIZE STANDARD AT ONCE • Instant conversion chart: US/CA, UK/AU, EU/ISO millimetres and Japan — side by side. • Pick your preferred standard in settings; switch anytime. • See the exact inner diameter in mm behind every size. ON-SCREEN RULER • A real calibrated ruler in mm, cm and inches, with a draggable guide line. • Calibrate once for your exact display — re-calibrate anytime for any device. • Copy the measured value with one tap. BUBBLE LEVEL • Surface mode: lay the phone flat and level anything with a live x/y bubble. • Edge mode: rest the phone on its edge and read the angle in degrees — hang shelves and frames straight. • Set zero on any known-flat surface to cancel sensor bias. SAVE, SHARE, PRINT • Save sizes — yours and the people you choose gifts for. • Share a size in seconds when you order a ring online or at the jeweler. • Print a paper ring sizer to double-check before a lifetime moment — engagement, wedding, anniversary. PRIVATE BY DESIGN Mesurix works entirely on your device. No account, no sign-up — your measurements stay with you. Whether you are choosing an engagement ring, ordering jewelry online, sizing a gift without spoiling the surprise, hanging a shelf straight, or just need a quick ruler in your pocket — Mesurix gives you the right measurement the first time.

Check the size of small everyday objects with the iPhone or iPad you already have with you. EasyRuler keeps the whole screen available for measuring, with the controls there when you need them. A ruler across the whole screen Read metric and imperial markings side by side. Use the clean static ruler, or switch to two movable markers and read the distance between them. Turn your device to use portrait or landscape. Match the whole scale Place a real ruler alongside your device, align the zero marks and adjust the full visible scale. Compare the far end and the marks in between as the screen updates. Save when ready, or cancel without replacing your previous calibration. A standard bank card reference is available when no ruler is nearby. Fine adjustments, fewer accidental taps Use the plus and minus controls to move either marker in 0.1 mm steps. Lock the aligned markers, then tap a blank area to hide or show the unlock button. When unlocked, a tap on the ruler hides or shows the normal controls. Simple by design Pay once to download; all features are included. No ads, subscriptions, in-app purchases or accounts. Measuring and calibration work offline. Settings are saved locally, and your measurements are not uploaded to us. The interface follows your device's light or dark appearance. Before measuring Accuracy depends on the device, your calibration reference and how you align it. The 0.1 mm adjustment step does not guarantee 0.1 mm physical accuracy. Use a reliable real ruler and check several marks before relying on a reading. The available measuring span depends on your screen size. EasyRuler is for everyday checks on the built-in screen, not professional or safety-critical measurement. External displays are not supported. For iPhone and iPad with iOS or iPadOS 16 or later.
