Font Up

As the elders in the family get older and their hearing becomes more or less poor, communication becomes extremely inconvenient, sometimes shouting out loud will not help.
Font Up is software for people with hearing impairments or family members with hearing impairments in the family. Just type out the words you want to say, and then adjust the font size and color to make it easier for people with hearing impairments to communicate with people with normal hearing.
Features:
* Use the entire screen to show what you want to communicate (iPhone or iPad)
* Font size and color can be adjusted freely
* Clear content with one click for easier communication
* Support dark mode
