My App is loading very slow. I have 4000 rows that each have a calculated column that shows

the difference between the current row and the previous row of the same ref. I need this info for graphing purposes. Would I be better off moving calculation onto the spreadsheet? Would this speed the app up?

Definitely worth trying. Spreadsheets are optimized for things like that.
