Is there any app to make fonts bigger or stretchable for Android based phones?

I have the Samsung Galaxy Cooper

It is not a problem making notes in English but now I try to

do notes in Thai to help speed learning & find the Thai fonts tough to read

at normal size in my memo app ( which also does not have font sizing )

I did find one app called Font Manager & it helps a little but only in messaging

Anything else available that would help Thai script fonts in memo type apps

appear larger?

Thanks

semi sorted.....

I have found that a app called Color Note

Works nice for notes & has adjustable font size so Thai Script looks ok

For the phone Font Manager works well.
