I would like to easily distinguage my GUI from the figures when pressing Alt+Tab so I can access it faster. Now when I run the GUIs they have the same icon as a regular figure...

How do you change the icon in the upper left of the .mlappp GUI launched from AppDesigner?

Starting with R2020b, you can now specify custom icons for UI figure windows and toolbar push and toggle tools. See the release notes here.

R2020b OR Last version
function startupFcn(app)
app.uifigure .Icon='logo.png';
end
OK!

Add this to your startupFcn:
t = 0;
tMax = 5;
dt = 0.1;
while ~isfield(struct(struct(app.UIFigure).Controller), 'PlatformHost') && t < tMax
% Keep waiting until the window is found.
t = t + dt;
pause(dt)
end
win = struct(struct(struct(app.UIFigure).Controller).PlatformHost).CEF;
win.Icon = 'C:\Folder\MyIcon.ico';
Of course, you may have renamed the UIFIgure property of your app.
In R2016b and older, replace 'PlatformHost' with 'Container'.
