Welcome Kevin.
"The first app will input the data to firebase then the second app will display the data from the firebase? "
I think it is possible. Here is an example of a CloudDB app that contains both the send and receive parts in a single app. The input is password protected, the part that inputs data, while receiving is unrestricted. One app supports both functions but restricts who can input. Not two separate apps but it works like two.
The CloudDB is similar to Firebase. You certainly could do something similar using Firebase using a single app for input and data retrieval..
You might find this example useful:
