Need a stage plot and input list for your next gig? Plotly lets you drag your band's gear onto a stage diagram, list every channel, and send one tech-rider PDF to the house engineer — right from your iPhone. Add vocals, guitars and other instruments, drag them into position, fill in your inputs and tap Make Stage Plot PDF. The plot comes first, followed by the input list. • DRAG-AND-DROP STAGE — place up to 24 markers on a stage canvas seen from the audience, with the front of the stage at the bottom and upstage marked. • INSTRUMENT TYPES — vocal, guitar, bass, drums, keys, brass/horns, DJ, monitor or other, each with its own name you can rename. • INPUT LIST — up to 48 channels with channel number, input name, mic or DI, and notes (e.g. "Ch 7 · Lead Vox · SM58 · wireless"). • ONE TECH PDF — stage plot and input list together in a single US Letter PDF, with your band name and show or venue in the header. • QUICK EDITS — reset the layout, remove a marker or reorder channels in seconds. Print with AirPrint, share the PDF with the venue or save it to Files. Everything is made on your iPhone — no account, no sign-up. Your first 3 stage plots are free. A one-time $4.99 unlock gives you unlimited stage plots and input lists. No subscription, no ads. Questions: overlapmarr@gmail.com
