Quick guide

Using Flash Sign Banner

Create a banner

Open the app, create a new banner, type your message, choose your text and background colors, then save it for later or show it right away.

Present full screen

Tap a saved banner to show it full screen. Use large, short messages for the best readability across a room or crowd.

Use Siri to show a banner instantly

On iPhone, say Hey Siri, show a sign in Flash Signs or Hey Siri, make a sign in Flash Signs. When Siri asks for the text, say the message you want shown. Flash Signs creates the banner and presents it full screen.

Set up Siri shortcuts

If Siri does not recognize the phrase yet, open Flash Signs once, then check the Shortcuts app for the Flash Signs action. You can add your own shortcut phrase there.

Choose a preset

Use Still for simple signs, Scroll for longer text, Flash for attention, Mirror for glass/window use, and the motion presets when you need extra visibility.

Use countdowns

Countdown placeholders can be written inside a message, such as Back in [2:00m]. The countdown updates while the banner is presented.

Keep it readable

Short words, high contrast, and fewer lines usually work best. If people need to read it quickly, make the message simpler.

Troubleshooting

Things to try first

The sign is hard to read

Try a shorter message, a larger font size, and a high-contrast pair like gold on black or black on white.

A countdown does not look right

Check the placeholder format and keep it simple, for example [2:00m]. If it still behaves unexpectedly, send us the exact text you entered.

Siri does not open the banner

Make sure Siri is enabled for the app, then say Hey Siri, show a sign in Flash Signs. Siri should ask for the banner text before opening the app. You can also try Hey Siri, make a sign in Flash Signs.

You reached the saved banner limit

The free version supports up to five saved banners. Unlimited saved banners are available through Apple in-app purchase.
