What are the limitations of AppSheet?
Actual limits
For an AppSheet app, the compressed data size limit is 5MB or 10MB (depending on the device) for all the data in one app. It is difficult to translate this accurately into a specific number of rows or columns because compressed data size depends on how much repetition there is in the data.
