About

Orbita is a ring sizer from the VIKOZA jewelry house. Put a ring on the screen, stretch the glowing circle until it matches the inner edge, and read the size right away. HOW IT WORKS • Place the ring you already wear on your iPhone or iPad screen. • Move the slider until the circle meets the inner edge of the ring. Steps of 0.1 mm, from 14 to 23 mm. • See the diameter and circumference in millimetres and the size in the system you need. FIVE SIZE SYSTEMS RU (diameter), EU (circumference, ISO 8653), US, UK letters and JP. Switch between them with one tap. Useful when a shop lists only US or EU sizes, or when you are choosing a ring as a gift. CALIBRATED TO YOUR DEVICE Orbita converts millimetres to screen points using the physical screen size of your iPhone or iPad model, so one millimetre on screen is one millimetre of ring. No credit card or coin needed for calibration. NO RING AT HAND Wrap a strip of paper around the finger, measure it with a ruler and enter the length: Orbita converts the circumference to a diameter and shows all five systems. A toggle for wide bands adds the half size they need. CALIBRATE WITH A BANK CARD Put any ID-1 card on the screen and match the frame to its edges. The correction is saved and applied to every measurement. GIVE ME A RING Share a card with your size in RU, EU, US, UK and JP and a link to VIKOZA. Whoever receives it knows exactly what to order. THE VIKOZA CATALOG Ephemerides, Asteroid, Particles, Wanderer and Spark: browse the pieces, read about each organism and go to the site to acquire one. PRIVATE AND OFFLINE No account, no sign-up. Measuring works offline; the internet is used only for catalog photos and the link to the site. The app collects no data. FROM SIZE TO JEWELRY VIKOZA is a jewelry house where every object exists in a single copy. Send the size you measured to the VIKOZA workshop and have your own piece made.
