I think you’re referring to the use of emojis, right? There are multiple reasons for that:
- Emojis are universal symbols for the online community. I could have done some custom illustrations and so on (you can see some early concepts here: https://dribbble.com/shots/2316448-Umbrella) but I felt like emojis give a better overview and they generally resonate better with our target audience. Everyone uses smiley faces on Facebook, Twitter and so on, so it gives a better understanding on what you want to transmit. Besides that, it adds a more playful feel to the app.
- Another reason is that we didn’t have to invest a lot of time with custom illustrations, so we could focus more on functionality. It also allowed quick development by using the emoji font instead of having to integrate custom icons on each page.
I hope my answer helps.
