Helping adding tab and adding apple watch springboard to app.

So i have this app, its the one with the blue nav bar that looks like yik yak. and then I have this watch springboard that works on iPhone. Basically all I need to do is create a new tab in the center of the yik yak app titled school.. Then I need All random icons (They can be whatever you want) And I need it too be the style of the apple watch home software when you click the tab so it will pull up all of the icons. I can give you the apple watch springboard code so you already have the code for it, I just need help implementing it.. Please message me with any questions.
