RingThing turns focus ring labels into something you actually want to put on your kit. Built for camera assistants working with ARRI Hi-5, ARRI WCU-4 or Tilta Nucleus M2 hand units (with others in development), it lets you design, preview and export beautifully laid out focus, iris and zoom ring labels straight from your iPhone. Open a .rng file exported from a Hi-5, or import ARRI, cmotion or Tilta LDA calibration tables for the lenses you're using — and RingThing renders a ring label that matches the engraved scales, mark for mark. DESIGN • Carefully drawn typography for imperial and metric focus scales, including superscript fractions and decimals. • Interpolated minor marks with adjustable density so dense ends of the scale stay readable. • Theme system with presets you can override; build and save your own themes, or import a friend's with a QR code. • Live preview with rotation, contrast cues and a print-accurate layout. SOURCES • Open .rng files exported from an ARRI Hi-5. • Import ARRI, cmotion and Tilta LDA (.tab, .cml, .tl) lens calibration tables — by file, by scanning a QR code, or from a photo. • Choose which scale to render from a multi-axis LDA: focus, iris or zoom. • Convert ARRI LDAs to Tilta Nucleus M2 LDA files (Pro) • Files restore on cold launch, so the lens you were just working on is right there when you re-open the app. EXPORT & SHARE • Print-ready PDFs and PNGs sized for A4 stock. • Crisp SVGs for design and cutting tools (Pro). • Themed story-image exports for sharing your work. • Optional contrasting border on print exports for cleaner trimming. • Share imported LDAs with the rest of your camera department. 3D-PRINTABLE APPLICATION JIGS • Share an STL for a left- or right-handed Hi-5, WCU-4 or Tilta Nucleus M jig and print one on any FDM or resin printer. • The jigs hold the labels squarely against the rings while you press down — no more wonky applications. PRO A one-time, no-subscription Pro purchase unlocks SVG export, .rng import, ARRI-to-Tilta LDA conversion, Data Matrix barcodes, persistent theme and LDA libraries, and saved custom themes. Free version users can take LDA imports for a test drive each session before deciding. Feedback and feature requests are very welcome via the Instagram link inside the app. ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | RingThing Pro | $19.99 | one-time | ## Version history (last 5 releases) ### 1.4.1 — 2026-06-24 Version 1.4.1 • Left-handed and reversed ring labels are now supported when using an LDA as the source. • New calibration ring label for troubleshooting any alignment issues. Version 1.4 • Tilta Nucleus M2 support. Generate labels for Nucleus M rings from any LDA - ARRI or Nucleus M2. • Import Tilta LDA files into your LDA library and work with them just like ARRI LDA files. • ARRI-to-Tilta LDA conversion (Pro) — convert an ARRI LDA into a Tilta Nucleus M2 LDA file and load it onto your hand unit. This can save you hours of prep time. • Tilta application jigs — share an STL to print a jig that holds a Nucleus label squarely on the ring. • Straight-strip labels — a no-taper layout for applying labels onto flat or 3D-printed custom rings. Version 1.3.1 • Adding a link to the new cutting machine workflow tutorial video. • Scale charts generated from LDA calibration data are now visible for each LDA file. Version 1.3 • More ways to customise your ring labels - gradients, new typefaces, style major and minor marks independently etc. • The 'above' label position option now stretches major marks all the way across the label width. • Experimental support for importing cmotion LDA files. Version 1.2.2 • You can now rename folders in the LDA library to fix any errors or abbreviations an LDA might contain. • Bug fixes for mark placement on labels generated from LDA files. Version 1.2.1 • Imperial focus scales now use only inches up until two feet, as per industry convention. • Social stories can now be generated in both 9:16 and 4:5 aspect ratios. • Fixed an LDA library display issue where Cooke lens names were not displaying correctly. • Duplicate LDA files are now ignored on import. Version 1.2 • WCU-4 ring support - format labels to fit WCU-4 / SXU-1 / cPro style rings. • LDA library feature added - import lens data in LDA (.tab) files and they are automatically organised by manufacturer, type, focal length and serial number. Share LDA files by QR code, messaing apps etc. • Generate focus, iris and zoom ring labels directly from LDA files. • Added a toggle to control whether a border is added to designs exported for print, to suppress it when using cutting machines. • 3D printable jigs for applying Hi-5 labels are now bundled in the app - get perfect alignment every time. Coming soon: • Support for Preston, Teradek and cmotion hand units. ### 1.3.1 — 2026-06-08 Version 1.3.1 • Adding a link to the new cutting machine workflow tutorial video. • Scale charts generated from LDA calibration data are now visible for each LDA file.
