There are two ways to add a text annotation in Xodo: from the top annotation toolbar and from the quick tools menu.

Method 1: From the top annotation toolbar

1. Select Annotate Toolbar. If you don't see the top toolbars, tap the center of your screen to bring it up.

Then tap the Text icon.

2. Tap where you want to add text.

Method 2: From the quick tools menu

Tap and hold on where you want to add text until the quick tools menu pops up, then tap Text icon.
