Ability to change source file storage from Open As App Cloud to One Drive, Dropbox or Google Sheet.

• To do this, navigate to "Update data source" and click "Edit URL"
• However, when the source file is synced to an online Google Sheet, database updates do not trigger automatic notifications.

Calculator app using Excel formulas can be designed easily.

• This is not feasible in AppSheet, Mdict or Wistify.app.

Reminder When Updating Source File

Changes to the spreadsheet (e.g., changing sheet names or moving cell entries) that are not made in the Editor cannot be detected automatically.

• If the structure of the new file is different from the file you created the initial app with, you have to make additional changes regarding the assignment in the app elements.

Summary

While Open As App remains feasible and useful, its Basic Free Plan is discontinued on 28 February 2025, and replaced with a 30-day Basic Trial Plan.

• After the trial, a paid subscription is required for continued service.
• Therefore, free alternative applications, such as AppSheet, Wistify and Caspio, may be considered.
