RingThing has launched a new iPhone app designed to help filmmakers and camera technicians create custom focus, iris, and zoom scale labels for popular hand units. The app supports ARRI Hi-5, ARRI WCU-4, and Tilta Nucleus-M II systems, offering a digital alternative to manual marking. By generating printable labels directly from a smartphone, RingThing aims to reduce prep time and improve consistency during camera setup.

The tool is particularly useful for content creators who rely on precise focus pulling and repeatable camera movements. Instead of hand-marking rings with tape or grease pencils, users can design clean, professional-looking scales within the app and apply them quickly. This not only saves time but also enhances readability under varying lighting conditions on set.

RingThing’s release addresses a common pain point in professional workflows: the inefficiency and inconsistency of manual focus ring labeling. By digitizing the process, the app supports faster turnarounds between shoots and better collaboration among camera teams. The iPhone-based interface ensures accessibility for users already working within Apple’s ecosystem.

While the app does not alter the hardware functionality of the supported units, it improves the user interface experience through clearer visual references. This can lead to fewer errors during focus pulls and greater confidence in complex shots. The solution aligns with the growing trend of software-driven efficiency in cinema production tools.

As of June 22, 2026, RingThing is available for download, offering a practical upgrade for creators using ARRI and Tilta follow focus systems. Its launch reflects ongoing innovation in accessories that bridge hardware usability with digital convenience. Creators focused on workflow optimization may find the app a valuable addition to their pre-production toolkit.
