In the OnSign TV App Library as described in the Creating an App tutorial, you find the category "Text and Scrollers". These are ideal for displaying short messages to be updated quickly on the go. Check out the available Apps below:
Rich Text Widget

This app is fully customizable! Change background and font colors, font size, line height, alignment, and page margin. You can separately apply different formats to specific text elements.
This App resizes automatically to fit any screen region. Just remember checking the “Auto-fit text size” box, so that the whole content is adjusted to the new area.

Even though this app will fit any screen region, we recommend to always preview the App and test how it looks published on a device before launching it to your entire network.
Text Scroller, Text Ticker, and Vertical Text Ticker

Sentences roll across the screen with the Text Scroller App or are shown as a one-liner in horizontal or vertical orientation. To separate lines of text, just begin a new line in the text box in the App settings.
Transitions in both Text Ticker Apps can be animated into a fading transition by checking the "Animate text transition" box. The speed of the Text Scroller App is adjustable to be faster or slower.

Keep the size of your screen in mind when writing your text. The longer the sentence, the smaller the font.
Note: For the Vertical Text Ticker, Capslock is the only available text format.
Message App

The Message App takes input from a Data Feed. If your Data Feed is an external source, you can change the message without even accessing your OnSign TV account. This is also useful if you don't want to provide access to an OnSign TV account to collaborators.
The Message App is color coded by degree of importance. Assign up to 3 different accent colors for the message. The labels can be adjusted to your needs. By default the labels and colors are red for important, yellow for warning, and blue for attention.
QR Code

Invite your audience to discover more information on their mobile, right from your screen! QR codes make calls-to-action much more effective by redirecting users straight to a website URL. You just need to paste the URL or message you want to display into the App settings. For more on the QR Code App read here.
Besides text Apps which are covered in this section, the OnSign TV platform has plenty more text-centric Apps to offer in the Menu Boards & Tables category, e.g. for tables or directories.
