■ Hold it up. It is already scrolling. Open the app and your message is on the screen — full width, landscape, in the colour and at the speed you left it. Nothing loads first. There is no advertisement between you and your sign, no trial sheet, no list to tap through. Zero taps from launch to a message someone across a room can read. That is the whole product: a phone you can hold up and be understood by. ------------------------------- ● Zero taps to the sign ------------------------------- • The last message you showed is scrolling on the very first frame. • The controls appear for two seconds and then fade away. That fade is the entire tutorial. • One tap anywhere brings them back, one more sends them away. • There is no loading spinner anywhere in the app, because there is nothing to load. • Switching to another saved message is two taps. Writing a brand-new one is three. ------------------------------- ● Made to be read across a room ------------------------------- • The letters are drawn as large as the screen allows — up to 320 pt tall. • Eight sign colours: ice cyan, white, amber, red, lime, pink, violet, azure. • Five scroll speeds, from a slow crawl to a fast run. • Changing the speed never makes the sign jump or start over — the letter under your thumb stays exactly where it is. • The screen is kept awake and the status bar hidden the whole time the sign is up. • Landscape both ways, so it reads correctly whichever way you turn the phone. ------------------------------- ● The messages you already have ------------------------------- • Saved messages sit in a row of chips. One tap swaps the sign; the one you just used moves to the front. • Up to 20 messages, most recent first. Delete one, or clear them all. • Four ready-made phrases in your language are there from the first launch, so the sign is never blank. • Every keystroke is written to this device as you type. There is no Save button because there is nothing to lose — take a call mid-word and the half-typed word is still there. ------------------------------- ● Right to left, properly ------------------------------- Arabic and other right-to-left messages enter from the left and leave to the right, so the reader sees the first word first. Cursive letters are never pulled apart by letter-spacing at sign size. ------------------------------- ● Private by design ------------------------------- • Zero network code. Nothing leaves this phone, ever — check it in airplane mode. • No system permissions at all: no microphone, camera, location, contacts, photos or notifications. There is no permission prompt anywhere in this app. • No account, no login, no sign-up. Privacy label: Data Not Collected. • Zero analytics. Zero telemetry. Zero third-party SDKs. • No ads. No subscriptions. Nothing to unlock. ------------------------------- ● Good for ------------------------------- • Concerts, fan meets and cheering sections • Airport and station pickups — a name that can be read from across the hall • A roadside breakdown, a parking note, a "back in 5" on a shop counter • A loud workshop, a noisy venue, a quiet ward • Anyone whose word needs to carry further than their voice ------------------------------- ● Built to be tapped ------------------------------- • Every control is at least 64 × 64 pt — easy to hit without looking. • Single taps only. No double-taps, no swipes, no hidden gestures. • Reduce Motion is respected: the message stops and is fitted to the screen instead of scrolling. ------------------------------- ● Languages ------------------------------- English · Korean · Japanese · German · French · Arabic ------------------------------- ● The Baro promise ------------------------------- LED Banner is part of Baro — lightweight tools that respect your data, your battery, and your time. "The tools you reach for first."
