One big app or multiple small connected apps?

One big app or multiple small connected apps?

I have a question for everyone on their thoughts and knowledge with app design. I was originally using Appsheet before coming back to Zoho Creator. I am building an app or apps for my house flipping business and it has many facets such as CRM, project management, logistics, material lists, etc, etc. With Appsheet, the more tables, forms, and data you had in one app, the slower it became and would take minutes for the backend to reload after each edit. Creating multiple connected apps was way too cumbersome. With Zoho Creator being as awesome as it is, I am seeking to see for any advice or suggestions if smaller connected apps would be better or having one app that contained all the elements I am building.  I appreciate any suggestions and benefits or drawbacks.

Thank you
