2 Creating a Custom TinyWebDB Service (App Inventor 2)
TinyWebDB is an App Inventor component that allows you to store data persistently in a database on the web. can be used to facilitate communication between phones and apps (e.g., multi-player games). By default, the TinyWebDB component stores data on a test service provided by App Inventor, This service is helpful for testing, but it is shared by all App Inventor users, and it has a limit of 1000 entries. If you use it, your data will be overwritten eventually. For most apps you write, you'll want to create a custom web service that isn't shared with other App Inventor apps and programmers.
