WebDB Service for App Inventor

WebDB Service is an App Inventor data source (API) that allows you to store the app's data persistently in a web database. You can use Web Component to access from an Android app.

This feature improvements from Tiny WebDB Service

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.
