Regarding the logo, I went for a triangle kind of shape because I had three-way in my mind... app, pet owner and their pet. At the bottom of the triangle, it looks like it could be a tail. Also, I wanted to go for the 'simplicity' look that stands out... stronger enough that doesn't need an image of a pet animal on the login screen. At the same time, keeping the designs clean. I gone for deep sky blue because this colour, I feel, comes across as being positive and fresh. Any feedback would be appreciated!
