The weather software that comes with the mobile phone is not allowed. Is it reliable to come up with a new ink weather APP?

Let's just say that my friends and I like to ink the weather. The weather forecast is quite accurate. I heard that ink weather ranks first in the coverage rate of active users in similar software! If it doesn't work, there shouldn't be so many people using it. After all, it has been a company for ten years, and they are still excellent in meteorological services.
