Should be available in the free version. The only limitation is you can only create one panorama.
1. Open iPanorama 360 Project
In “General” make sure “Enable” is selected.
2. Select “Scene” you want if you have multiple. (Make sure it is enabled)
3. Go to “Markers” (either add new, or make sure you actually select a marker in the left pane. It will turn blue when selected.)
4. In your marker you will want to go to “Actions”, then “Go to a scene”, then select the next scene. i.e. the room you want to go into. You have to make the next scene before you can select it. (Your example looks like you know the steps to this point.)
5. Above the right pane you should see “ToolTip” button.
6. Click on it.
Make sure you “Enable it”
Type in your text here. i.e. the name of the room.
7. In the preview window will be the “target” to allow you to move the hotspot where you want it. i.e. on the door to the room you want to enter. (Or just show the name for.) Just click on the target and drag it where you want.
8. Below that click the “Additional” button.
9. Then click the “Trigger” button, select the action you want to happen.
Save everything, and preview it.
10. Add lots of other fun things!
