I create these assets at home creating firstly Illustrator and after that i created a GIF in Photoshop using the timeline. Which I then saved as a GIF. For the side Bar I reused some of my App background and halfed it. I used the same colour to help it blend in with the app. I then reused the Text profile boxes and placed peoples names there as a place holder.
The second one is a drop down menu for hobbies and can be reused all over the app due to the button shapes and colours. When you click an option to show it active I have chosen to use the same green as the front screen.
The Third GIF is something that appears when you go no the search local function on the app. This will show that the app is search your area for people with the app (who you are friends with).
