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.

Verdict
The clearest difference is in-app purchases: IAMA+ at none against RingThing's 1. IAMA+ also leads on iOS requirement (15.0 vs 18.6). On price, update cadence, ads and device support there is nothing between them.
