Is there any charge for large-character weather?

No charge. According to the official website of DaZi Weather, we learned that the DaZi Weather software is a free version and looks clearer. The large-print version of the weather forecast is easy to read, which is good news for people with tired eyes. The large-print weather forecast application is targeted at older people and people prone to vision problems. It comes with a 40-day weather forecast and a detailed monthly calendar.
