Please note that if you need to change the columns number select TableArrangement1 component, go to Properties pane of TableArrangement1 and change Columns field number to 5 and Rows field number to 1.Ħ.Select the Button1 component and click on Rename button. We will need five buttons for our stopwatch app. To use a Button component in your app, you need to click and drag it from the User Interface palette into the Viewer. From Layout pallete drag out the TableArrangement1 component and drop it in the Viewer.ĥ. We will use TableArrangement for our buttons, it’s the formatting element which is used as a place for components that should be displayed in tabular form. We assume that you have read our previous projects about MIT App Inventor 2.ġ.Go to and click on Create Apps! orange button.Ģ.Click on Start new project and give your project a name, you can name it as Stopwatch. We will learn how to build stopwatch app with the MIT App Inventor 2 software.
