If you have asked whether your team should use Power Apps or Power BI, you are asking the right question in the wrong order. They are not rival products fighting for the same job. One builds tools your people use to do work. The other builds the pictures you look at to understand the work. Once that difference is clear, choosing becomes easy, and more often than not the answer is both.
Power Apps creates apps: forms, screens and buttons that replace spreadsheets, paper and chasing. Someone opens the app, enters data or starts an approval, and the record is saved to a shared data source. Power BI creates reports and dashboards: charts, tables and key figures that turn that data into a view leadership can read. The simple version is that Power Apps is where work happens, and Power BI is where you see what happened.
