StageTools is a lighting toolkit for iPhone and iPad, built for the work that happens before, during, and after the rig is in the air. Scout the job. Plot the rig. Troubleshoot the network. Check DMX. Keep fixture data, files, notes, and utility tools close without opening a laptop. TOOLBOX Network Devices scans your show network and helps you keep track of nodes, switches, consoles, and other devices. DMX Viewer listens to sACN and ArtNet so you can inspect live universe data and catch channel changes. Micro Console gives you a pocket-sized lighting console for fixture testing, quick looks, and controlled sACN or ArtNet output when you need it. Protocol Detector passively listens for common show-network traffic so you can see what is talking before you change anything. LTC Timecode can generate, receive, or jam timecode from your device. Curve Builder helps build fixture correction references from meter readings and export them for real show workflows. DIP Switch and CCT Converter cover the small calculations that still come up on set and in the shop. QUICK PLOTS Build fast lighting plots, network layouts, and power notes on one canvas. Add symbols, labels, cables, layers, backgrounds, custom symbols, and exports to PDF or PNG. SCOUT NOTES Create location scouts with photos, videos, marked-up images, note tabs, voice memos, transcripts, files, and PDF export. Make Scout Notes can turn a voice transcript into structured notes you can review and insert. FIXTURES Search, download, favorite, and reference fixtures from the GDTF Share Library. Downloaded fixtures can be used across StageTools workflows. FILES Save links, PDFs, manuals, plots, patch sheets, network diagrams, and local files. Organize by folder, category, and favorites, then share folder bundles when another StageTools user needs the same packet. BUILT FOR LIGHTING WORK StageTools is focused on lighting professionals: set lighting crews, theatrical electricians, lighting designers, programmers, gaffers, and touring techs. Many tools work offline. Live network tools require access to the show network. Core data stays on your device, with optional iCloud Sync for your own devices. StageTools is free to try. A subscription unlocks the full lighting workflow after the trial. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
