Plotwright
Read full descriptionHide full description
Plotwright builds the two documents every gig needs — a stage plot and an input list — and turns them into one clean, print-ready PDF you hand to the venue's sound engineer. Pay once. No subscription, no account, no WiFi required. It's made for the band member who got volunteered to "make the tech rider" and the front-of-house engineer who has to read it in dim light at load-in. What you build on screen is exactly what prints — no fuzzy export, no surprises at soundcheck. WHAT YOU GET • A top-down stage plot you build by dropping in simple, map-like symbols for the gear on stage — like drums, amps, monitors, DIs, and risers. Move, resize, rotate, rename, or duplicate anything. • An input list that numbers itself in the order engineers expect — kick, snare, toms, overheads, bass, guitars, keys, vocals — so you look like you know the convention even if you don't. Reorder by hand any time. • One-page output with the plot and the numbered input list on the same sheet. • A true-vector PDF that stays sharp and reads cleanly in black and white — because it's getting printed and folded into someone's back pocket. BUILT THE WAY THE SHOW ACTUALLY RUNS • Stage orientation is fixed and labeled — audience at the bottom, stage left and stage right from the performer's point of view — so no one patches the stage backwards. • Your act name, contact, and the date it was last edited are burned into the PDF, so the engineer always knows whose plot it is and how current it is. • Everything stays on your device. No cloud, no sign-in, nothing to sync. FREE TO BUILD, ONE-TIME UNLOCK TO EXPORT Build your plot, add your gear, and preview the finished page for free. A single one-time purchase unlocks PDF export, save, and share — for good. No subscription. No paywall in your way while you work. Made for gigging musicians, bands, and the live-sound engineers who advance their shows.

Verdict
The clearest difference is in-app purchases: Frequency Detector Tool at none against Plotwright's 1. Frequency Detector Tool also leads on iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.
