Pokemon GO is an AR collection game made by Niantic. The basics of the game is that you walk around in real life and Pokemon appear on your phone. You can then catch and collect the Pokemon to be used in battle or to brag to your friends.
Pokemon Go uses a lot of flat design for their UI. It's very modern and sleek with rounded edges and crisp lines. It's buttons are minimalist in style with line art icons and solid background colors. It tries to keep some themes similar to the Pokemon games including the Pokemon and items.
Pokemon uses a Sans Serif font called Lato. This font has a rounded feel to it but has sharp ends to the letter forms. It treads the line between structure and friendliness. For titles, Pokemon Go uses a bolder version of Lato while using a lighter version for content writing.
Pokemon Go does an excellent job of keeping it's colors consistent throughout it's UI. Most UI elements are a seafoam green color with a gradient to yellow green. Pokemon Go also uses orange to indicate important events happening in the world like raids. Purple is used sparingly and is used mostly to indicate tracked Pokemon. All pop-up elements are an eggshell color with a background blur on it. The main use of color in the game is attributed to the faction chose by the player. A lot of the colors are picked from the faction. If you're part of Team Mystic, your buddy walk meter is blue (mine is red because I chose Team Flare).
The nicest thing about Pokemon go is that the "X" (close button) is located at the bottom of the screen. This way, you can open and close a menu quickly and easily without reaching too far. However, I feel like a lot of the opening and closing menus could've been avoided. When choosing a new Pokeball, we could easily have a button on the screen rather than a menu, same with berries. The game is also inconsistent with it's color choices. Some close buttons are green while others are white and would've stood out more as a green button.
