I'm not familiar with the MIT App Inventor, so I cannot comment on that specifically.

In general, If you are building an app you can use ThingSpeak's RESTful API to query for points on the channels and display it on your app. For example, to get the most current data from channel 9 of ThingSpeak, you can do this:

https://api.thingspeak.com/channels/9/feed/last.json

Your app will need to make the RESTful call and parse the field value to display the current value.

When Web services use REST architecture, they are called RESTful APIs (Application Programming Interfaces). You can read up more about REST here:

It is actually quite easy to build an MIT App Inventor App to display ThingSpeak data. Please see the following post on my blog for an example of how to do this: http://www.mawrey.com/simple-thingspeak-viewer-app-using-mit-app-inventor-2/
