With so many weather forecasting software, why do ink weather users have the most?

The most popular function of ink weather is the travel function. I'm a traveler, so I have to check the weather at my destination before I go out, but I don't know how many degrees Celsius it is. Just looking at the figures, I am still worried about what to prepare, and there are no local friends to consult. There is a cross-city trip in Ink Weather, which will compare the temperature and humidity of the two cities and provide corresponding suggestions, such as what kind of cosmetics to bring and whether to wear a mask. It's really sweet.
