Pixels are the smallest physical element that we can control on a digital display. The more pixels can be fitted into a specific screen size, the higher the PPI (pixels-per-inch), and the clearer the rendered content becomes.
Points are a resolution-independent measurement. Depending on the screens pixel density, a point can contain multiple pixels (e.g., 1 pt contains 2 x 2 pixels on a regular retina display).
When you are designing for various display types, you should think in points, but design in pixels. This means you will still need to export all your assets in 3 different resolutions, no matter in which resolution you are designing your app.
